Description

Technical Field

[0001] This application relates to the field of smart door lock technology, and more specifically, to a method for authenticating the authenticity of battery accessories for smart door locks, a smart door lock, and a terminal. Background Technology

[0002] In daily life, smart devices, including smart door locks, frequently require battery replacements. These replacements can be lithium batteries, dry cell batteries, etc. Because battery components are consumables and relatively easy to manufacture, many manufacturers, driven by commercial interests, produce counterfeit or substandard battery components. These counterfeit components typically fail to meet the standards of original parts, leading to frequent malfunctions and impacting the usability of the smart devices. For example, if a smart door lock uses counterfeit lithium or dry cell batteries, it cannot provide a stable power supply that meets lock standards. This is especially problematic for smart door locks with network connectivity or multiple unlocking methods. Unstable power supply can cause some core components to malfunction, resulting in issues such as frequent device offlineing, inability to pair with the network, failure to unlock using fingerprint, finger vein, card, or palm vein recognition methods, accidental low battery alarms, and even damage to the lock itself. These issues severely impact the user experience.

[0003] Therefore, how to avoid unstable power supply and inability to connect to the network due to users using counterfeit or substandard battery accessories is an urgent problem to be solved. Summary of the Invention

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0048] The technical solutions of this application and their effects are described below through several exemplary embodiments. It should be noted that the following embodiments can be referenced, borrowed from, or combined with each other. Identical terms, similar features, and similar implementation steps in different embodiments will not be repeated.

[0049] Figure 1This is a schematic diagram of the system architecture for implementing a method for authenticating the authenticity of battery accessories for smart locks, as provided in this application embodiment. It includes a smart lock 110, a terminal 120, and a cloud platform 130. The cloud platform 130 includes an IoT platform 131 and an accessory management platform 132. The smart lock 110 is an improvement on traditional mechanical locks, offering greater intelligence and convenience in terms of user security, identification, and management. The smart lock 110 includes an electronic lock cylinder for electronic unlocking and a mechanical lock cylinder for mechanical unlocking. Electronic unlocking methods include facial recognition, fingerprint recognition, voice recognition, and magnetic card recognition. The smart lock 110 contains a battery accessory 111 to be authenticated. The battery accessory 111 can be installed in the battery slot of the smart lock 110 and can be a lithium battery, dry cell battery, etc. Terminal 120 and smart lock 110 are bound together. Terminal 120 contains the control program corresponding to smart lock 110, which can be used for unlocking, after-sales service, etc. Terminal 120 can be a personal computer, tablet, mobile phone, or other device. IoT platform 131 is the IoT platform for battery accessories. It is an extension and expansion of the internet, forming a vast network that combines various information sensing devices with the network, enabling interconnection between people, machines, and things anytime, anywhere. Accessory management platform 132 is the accessory management platform for battery accessories. Accessory management platform 132 records accessory identifiers for battery accessories whose battery information has been successfully programmed.

[0050] Among them, the smart door lock 110, terminal 120, IoT platform 131, and accessory management platform 132 perform the authenticity authentication method for the smart door lock's battery accessories through the following interaction:

[0051] In this embodiment of the application, the smart door lock 110 responds to the installation of a battery accessory 111 to be authenticated on the smart door lock 110 and sends a first authentication request to the terminal 120 bound to the smart door lock 110; the first authentication request is used to instruct the acquisition and decryption of the encrypted information of the battery accessory 111.

[0052] Terminal 120 receives a first authentication request sent by the smart door lock, and in response to the first authentication request, obtains and decrypts the encrypted information of the battery accessory to obtain the accessory identifier of the battery accessory; Terminal 120 sends a second authentication request carrying the accessory identifier to the accessory management platform 132 of the battery accessory through the Internet of Things platform 131. The second authentication request is used to instruct the accessory management platform 132 to perform authenticity authentication on the battery accessory 111 based on the accessory identifier.

[0053] The IoT platform 131 receives and forwards the second authentication request.

[0054] The accessory management platform 132 receives the second authentication request and authenticates the battery accessory 110 based on the accessory identifier of the battery accessory, and obtains a first authentication result or a second authentication result; the first authentication result is used to indicate that the battery accessory 110 has passed the authentication; the second authentication result is used to indicate that the battery accessory 110 has passed the authentication step.

[0055] The parts management platform 132 sends the first authentication result or the second authentication result to the Internet of Things platform 131 via network transmission;

[0056] If the IoT platform 131 determines that the smart door lock 110 is not connected to the Internet, it will send the first authentication result or the second authentication result to the terminal 120 through network transmission, and instruct the terminal 120 to send the first authentication result or the second authentication result to the smart door lock 110 via Bluetooth.

[0057] If the IoT platform 131 determines that the smart door lock 110 is connected to the Internet, it will directly send the first authentication result or the second authentication result to the smart door lock 110 through network transmission.

[0058] This application embodiment can provide an authentication system for battery accessories of a smart door lock. The authentication system includes the aforementioned smart door lock 110, battery accessory 111, terminal 120, and cloud platform 130 (including IoT platform 131 and accessory management platform 132).

[0059] This application provides a method for authenticating the authenticity of battery accessories for smart locks, applicable to smart locks, such as... Figure 2 As shown, the method includes:

[0060] In step S201, in response to the battery accessory to be authenticated being installed on the smart lock, a first authentication request is sent to the terminal bound to the smart lock. The first authentication request is used to instruct the terminal to obtain and decrypt the encrypted information of the battery accessory, so that the terminal responds to the first authentication request to obtain and decrypt the encrypted information of the battery accessory, obtains the accessory identifier of the battery accessory, and sends a second authentication request to the cloud platform of the battery accessory. The second authentication request carries the accessory identifier and is used to instruct the cloud platform to perform authenticity authentication of the battery accessory based on the accessory identifier.

[0061] Since the battery accessories installed in smart locks may be counterfeit from illegal manufacturers, if counterfeit battery accessories are used, the smart lock may experience frequent device offline, inability to unlock, accidental low battery alarms, or even burnt-out locks. To avoid these situations, this application embodiment performs authenticity verification on the smart lock after determining that the battery accessories to be certified are installed in the smart lock.

[0062] The battery accessory in this application embodiment can be any battery accessory that can be installed in the battery slot of a smart door lock. The battery accessory can be a lithium battery, a dry cell battery, etc., and this application embodiment does not limit it.

[0063] In this embodiment of the application, after detecting that a battery accessory to be authenticated is installed on the smart lock, the smart lock generates a first authentication request and sends the first authentication request to the terminal bound to the smart lock. The first authentication request is used to instruct the acquisition and decryption of the encrypted information of the battery accessory.

[0064] In this embodiment of the application, the terminal can be registered in the after-sales application of the smart lock to establish an association between the terminal's identity information and the smart lock's SN code, thereby achieving the binding between the smart lock and the terminal.

[0065] This application embodiment includes a battery accessory comprising an NFC chip or identification code for storing encrypted information. The NFC chip can be of any shape, such as an NFC coil, and this application embodiment does not impose any limitations on this. The identification code can be a QR code, or it can be a barcode, a 3D code, or a numeric sequence code, etc., and this application embodiment does not impose any limitations on this.

[0066] In this application embodiment, the NFC card reader included in the smart door lock is a first NFC card reader; the NFC card reader included in the terminal is a second NFC card reader.

[0067] In this application embodiment, the first or second NFC card reader can read information stored in the NFC chip (which may include encrypted information). When the distance between the first or second NFC card reader and the NFC chip is less than a preset distance threshold, "NFC tap-to-tap" is achieved. "NFC tap-to-tap" enables the first or second NFC card reader to read information in the NFC chip. For example, the second NFC card reader in the terminal can read encrypted information in the NFC chip through "NFC tap-to-tap".

[0068] The battery accessories in this application embodiment may also include an identification code, which may also store the encrypted information. The terminal can scan the identification code to obtain the encrypted information. Specifically, after entering the "Accessory Authentication" page, the terminal uses the "Scan" function to scan and identify the identification code storing the encrypted information to obtain the encrypted information.

[0069] The encrypted information in this application embodiment is obtained by encrypting the accessory identifier of the battery accessory. The accessory identifier of the battery accessory is different from the SN code of the battery. Although both the SN code and the accessory identifier can uniquely identify the battery accessory, the SN code is usually recorded on the outer packaging of the battery and is visible to the user, while the accessory identifier is not visible to the user.

[0070] After receiving the first authentication request, the terminal reads the NFC chip or scans the identification code of the battery accessory using its second NFC reader to obtain the encrypted information of the battery accessory, and decrypts the encrypted information of the battery accessory to obtain the accessory identifier of the battery accessory.

[0071] After obtaining the accessory identifier of the battery accessory, the terminal generates a second authentication request carrying the accessory identifier and sends the second authentication request to the cloud platform. The second authentication request instructs the cloud platform to authenticate the authenticity of the battery accessory based on the accessory identifier. The cloud platform includes an IoT platform and an accessory management platform. Specifically, the terminal can send the second authentication request to the IoT platform of the battery accessory and instruct the IoT platform to forward the second authentication request to the accessory management platform of the battery accessory, so that the accessory management platform can authenticate the authenticity of the battery accessory based on the accessory identifier.

[0072] Upon receiving the second authentication request, the battery accessory management platform performs authenticity verification on the battery accessory to be certified based on the accessory identifier carried in the second authentication request, obtains the authentication result, and sends the authentication result to the smart door lock. The authentication result is used to indicate whether the battery accessory has passed the authentication. The authentication result includes a first authentication result or a second authentication result, wherein the first authentication result indicates that the battery accessory has passed the authentication and is a qualified battery; the second authentication result indicates that the battery accessory has failed the authentication and is a substandard or counterfeit battery.

[0073] Step S202: If the cloud platform receives the first authentication result in response to the second authentication request, and the first authentication result indicates that the battery accessory has been authenticated, then a first message is displayed, indicating that the battery accessory has been authenticated.

[0074] If the smart lock receives the first authentication result, it determines that the battery accessory to be installed has passed authentication and displays a first message indicating that the battery accessory has passed authentication. This first message can be a text message or a voice message. Specifically, if the smart lock includes a display screen, the first message can be displayed as text; if the smart lock does not include a display screen, the first message can be played as voice, for example, "The currently installed lithium battery is a qualified battery and can be used normally with the smart lock."

[0075] This application embodiment uses the interaction between the smart lock, the terminal, and the cloud platform of the battery accessories to authenticate the authenticity of the battery accessories installed in the smart lock. This prevents the smart lock from being installed with counterfeit batteries, which could cause the smart lock to frequently go offline, be unable to connect to the network, fail to unlock using the electronic unlocking method, accidentally trigger the battery alarm, or even burn out the lock during subsequent use, thus improving the user experience of using the smart lock.

[0076] This application provides a possible implementation method, which involves sending a first authentication request to a terminal bound to the smart lock, and then further includes:

[0077] If the cloud platform receives a second authentication result in response to the second authentication request, the second authentication result indicates that the battery accessory authentication failed, and a second message is displayed; the second message indicates that the battery accessory authentication failed, and instructs the user to replace the battery accessory.

[0078] If the smart lock receives the second authentication result from the battery accessory management platform in response to the authentication request, it determines that the battery accessory has passed authentication and displays a second message indicating that the battery accessory has failed authentication. Similarly, this second message can be a text message or a voice message, for example, "The lithium battery authentication is unqualified; please install a qualified lithium battery."

[0079] This application provides a possible implementation method in which the smart lock includes an electronic lock cylinder that unlocks electronically and a mechanical lock cylinder that unlocks mechanically.

[0080] The first message will be displayed, followed by:

[0081] If it is determined that the user has not replaced the battery parts, then determine the usage time of the unreplaced battery parts;

[0082] If the usage time is not less than the preset usage time limit, the electronic lock cylinder will be deactivated and a third message will be displayed. The third message indicates that the battery accessory has exceeded the usage time limit, the electronic lock cylinder has been deactivated, and the user is instructed to use the mechanical lock cylinder to unlock.

[0083] The smart locks in this application include electronic lock cylinders that are unlocked electronically and mechanical lock cylinders that are unlocked mechanically. The electronic unlocking method can be facial recognition, fingerprint recognition, voice recognition, magnetic card recognition, etc., while the mechanical unlocking method refers to unlocking the mechanical lock cylinder with a mechanical key.

[0084] In this embodiment, after determining that the certification result of the battery accessory to be certified fails, the user is instructed to replace the battery accessory. If the user does not replace the battery accessory within the valid time, the usage time of the unreplaced battery accessory is determined. If the usage time is not less than a preset usage time limit (e.g., 3 days), the electronic lock cylinder is deactivated, and a third message is displayed. The third message indicates that the usage time of the battery accessory has exceeded the usage time limit, the electronic lock cylinder has been deactivated, and the user is instructed to use the mechanical lock cylinder to unlock. For example, the third message could be: "Because you have not replaced the battery accessory with a qualified one within 3 days, you can no longer use facial recognition to unlock. After replacing the battery accessory with a qualified one, you can use facial recognition to unlock normally. Please use the mechanical key to unlock for now." Similarly, the third message can be a text message, which can be displayed on the smart lock's screen; or it can be a voice message, played via voice.

[0085] This application provides a possible implementation method in which the smart door lock includes a first NFC (Near Field Communication) card reader; the battery accessory includes an NFC chip; the NFC chip stores a first hash value of the accessory identifier; and the first authentication result carries the accessory identifier.

[0086] If the cloud platform receives the first authentication result in response to the second authentication request, the following steps also include:

[0087] Write the accessory identifier carried in the first certification result into the MCU (Micro Control Unit) of the smart door lock;

[0088] Read the written accessory identifier from the MCU unit and generate a second hash value for the written accessory identifier;

[0089] The first NFC reader reads the NFC chip of the battery accessory and obtains the first hash value of the accessory identifier in the NFC chip.

[0090] If the first hash value and the second hash value are determined to be different, a fourth message will be displayed. The fourth message indicates that the certification of the currently installed battery accessory of the smart lock has failed, and the electronic lock cylinder will be deactivated after the usage time of the currently installed battery accessory is not less than the usage time limit.

[0091] In this application embodiment, the first authentication result carries an accessory identifier. After receiving the first authentication result, the smart door lock writes the accessory identifier in the first authentication result into the MCU unit of the smart door lock to record the accessory identifier of the currently installed battery accessory.

[0092] In addition to storing encrypted information, the NFC chip of the battery accessory in this application embodiment can also store a first hash value of the accessory identifier. The first hash value can be generated by a preset hash algorithm. The preset hash algorithm can be a Secure Hash Algorithm (SHA) or other hash algorithms. This application embodiment does not limit this.

[0093] To prevent users from replacing the battery components in the smart lock after it has entered a sleep state, this embodiment reads the written component identifier from the MCU unit after the smart lock exits the sleep state (i.e., enters the wake-up state) and generates a second hash value for the written component identifier. At the same time, the smart lock can also read the NFC chip of the battery component based on its own first NFC card reader, thereby obtaining the first hash value of the component identifier in the NFC chip.

[0094] After obtaining the second hash value, the smart lock compares the first and second hash values. If they differ, it indicates that the battery was replaced while the smart lock was in sleep mode. A fourth message can then be displayed, indicating that the currently installed battery has failed authentication and that the electronic lock cylinder will be deactivated after the battery has been used for at least a specified period. For example, the fourth message could be: "The currently installed battery is unqualified. If the battery is not replaced within 3 days, the electronic lock cylinder will be deactivated." Similarly, the fourth message can be displayed on the smart lock's screen or played via voice.

[0095] The smart lock in this application embodiment has a first NFC card reader that can read the NFC chip installed in the battery accessory to obtain the first hash value of the accessory identifier. Based on the first hash value, the second hash value generated by the MUC module of the smart lock can be verified to determine the authenticity of the battery accessory. This realizes a "local closed-loop interaction" between the smart lock and the battery accessory installed in the smart lock, which is convenient for anti-counterfeiting detection without adding any additional costs.

[0096] This application provides another method for authenticating the authenticity of battery accessories for smart locks, applied to terminals, such as... Figure 3 As shown, the method includes:

[0097] Step S301: Receive a first authentication request sent by the smart lock bound to the terminal. The first authentication request is generated by the smart lock in response to the installation of the battery accessory to be authenticated on the smart lock. The first authentication request is used to instruct the acquisition and decryption of the encrypted information of the battery accessory.

[0098] Since the battery accessories installed in smart locks may be counterfeit from illegal manufacturers, if counterfeit battery accessories are used, the smart lock may experience frequent device offline, inability to unlock, accidental low battery alarms, or even burnt-out locks. To avoid these situations, this application embodiment performs authenticity verification on the smart lock after determining that the battery accessories to be certified are installed in the smart lock.

[0099] The battery accessory in this application embodiment can be any battery accessory that can be installed in the battery slot of a smart door lock. The battery accessory can be a lithium battery, a dry cell battery, etc., and this application embodiment does not limit it.

[0100] In this embodiment of the application, after detecting that a battery accessory to be authenticated is installed on the smart lock, the smart lock generates a first authentication request and sends the first authentication request to the terminal bound to the smart lock. The first authentication request is used to instruct the acquisition and decryption of the encrypted information of the battery accessory.

[0101] In step S302, in response to the first authentication request, the encrypted information of the battery accessory is obtained and decrypted to obtain the accessory identifier of the battery accessory. A second authentication request is sent to the cloud platform of the battery accessory. The second authentication request carries the accessory identifier and is used to instruct the cloud platform to authenticate the authenticity of the battery accessory based on the accessory identifier.

[0102] The encrypted information in this application embodiment is obtained by encrypting the battery information. After decrypting the encrypted information, the battery information is obtained. The battery information includes the accessory identifier of the battery accessory. It is worth noting that the accessory identifier of the battery accessory is not visible to the user.

[0103] Upon receiving the first authentication request, the terminal responds by acquiring and decrypting the encrypted information of the battery accessory, obtaining the accessory identifier, generating a second authentication request containing the accessory identifier, and sending the second authentication request to the battery accessory's cloud platform. The second authentication request instructs the terminal to authenticate the battery accessory's authenticity based on the accessory identifier. The cloud platform includes an IoT platform and an accessory management platform. Specifically, the terminal can send the second authentication request to the battery accessory's IoT platform and instruct the IoT platform to forward the second authentication request to the battery accessory's accessory management platform. Upon receiving the second authentication request, the battery accessory management platform performs authenticity authentication on the battery accessory to be authenticated based on the accessory identifier in the second authentication request.

[0104] This application embodiment utilizes the interaction between the smart lock, terminal, battery accessory IoT platform, and battery accessory management platform to authenticate the authenticity of the battery accessories installed in the smart lock. This prevents the installation of counterfeit batteries, which could cause the smart lock to frequently go offline, fail to connect to the network, fail to unlock via electronic unlocking, accidentally trigger battery alarms, or even burn out the lock during subsequent use, thus improving the user experience of using the smart lock.

[0105] Upon receiving the second authentication request, the battery accessory management platform performs authenticity verification on the battery accessory to be certified based on the accessory identifier carried in the second authentication request, obtains the authentication result, and sends the authentication result to the smart door lock. The authentication result is used to indicate whether the battery accessory has passed the authentication. The authentication result includes a first authentication result or a second authentication result, wherein the first authentication result indicates that the battery accessory has passed the authentication and is a qualified battery; the second authentication result indicates that the battery accessory has failed the authentication and is a substandard or counterfeit battery.

[0106] Step S303: If the cloud platform receives the first authentication result in response to the second authentication request, it is determined that the smart lock is not connected to the Internet, and the first authentication result is forwarded to the smart lock via Bluetooth; the first authentication result indicates that the battery accessory has passed authentication.

[0107] In this embodiment of the application, after the accessory management platform sends the first authentication result or the second authentication result to the IoT platform, the IoT platform can choose the link to send the first authentication result or the second authentication result. When the IoT platform determines that the smart lock is not connected to the Internet, that is, when it determines that the smart lock is not connected to the network, it sends the first authentication result or the second authentication result to the terminal. After receiving the first authentication result or the second authentication result, the terminal determines that the smart lock is not connected to the Internet and forwards the first authentication result or the second authentication result to the smart lock via Bluetooth.

[0108] After determining that the smart lock is connected to the Internet, the IoT platform directly sends the first or second authentication result to the smart lock via network transmission.

[0109] This application provides a possible implementation method in which the terminal stores the public key of a preset key pair; the cloud platform includes an Internet of Things (IoT) platform and an accessory management platform; the IoT platform stores the private key of the preset key pair; the accessory management platform stores a first key; and the encrypted information is generated by encrypting the accessory identifier using the first key.

[0110] Obtain and decrypt the encrypted information of the battery accessories to obtain the accessory identifier, including:

[0111] Obtain encrypted information from battery accessories;

[0112] The IoT platform sends a key acquisition request to the parts management platform, so that the parts management platform sends the first key to the IoT platform. The IoT platform encrypts the first key based on its private key to obtain the encrypted first key; the key acquisition request is used to obtain the first key.

[0113] Receive the encrypted first key sent by the IoT platform, and decrypt the encrypted first key based on the public key to obtain the first key;

[0114] The encrypted information is decrypted using the first key to obtain the accessory identifier for the battery accessory.

[0115] In this embodiment of the application, the encrypted information is obtained by encrypting the accessory identifier of the battery accessory with a first key. The first key is stored in the accessory management platform, but not in the smart door lock. The terminal stores the public key of the preset key pair, and the Internet of Things platform stores the private key of the preset key pair.

[0116] The first key in this embodiment is a symmetric key. Symmetric encryption uses the same key for both encryption and decryption; that is, the encryption key and decryption key are identical. The symmetric key uses a symmetric encryption algorithm. Common symmetric encryption algorithms include DES (Data Encryption Standard), DEA (Data Encryption Algorithm), AES (Advanced Encryption Standard), 3DES (Triple DES), RC2, RC4, and RC5 algorithms. The first key in this embodiment can be a symmetric key obtained based on any of the above symmetric encryption algorithms.

[0117] In this application embodiment, the public key and private key are asymmetric keys. Asymmetric encryption uses two keys: a public key and a private key. The public and private keys exist in pairs. If encryption is performed using the public key, decryption can only be achieved using the private key; conversely, if encryption is performed using the private key, decryption can only be achieved using the public key. Because encryption and decryption use different keys, this type of algorithm is called an asymmetric encryption algorithm. Common asymmetric encryption algorithms include RSA, ElGamal, knapsack, and ECC (elliptic curve cryptography). The key pair consisting of the public and private keys in this application embodiment can be generated based on any of these asymmetric encryption algorithms.

[0118] like Figure 4As shown, an exemplary flowchart illustrates the interaction process for decrypting encrypted information. This involves the interaction between a terminal, an IoT platform, and a parts management system, including the following steps: The terminal sends a key acquisition request to the IoT platform to obtain a first key; the IoT platform forwards the key acquisition request to the parts management platform; the parts management platform includes the first key, and in response to the key acquisition request, sends the first key to the IoT platform; to prevent the first key from being leaked, the IoT platform encrypts the first key using the private key from its own preset key pair, obtaining an encrypted first key, and transmits the encrypted first key to the terminal via the network; the terminal decrypts the encrypted first key using the public key from the preset key pair, obtaining the first key, and uses the first key to decrypt the encrypted information to obtain the battery accessory identifier.

[0119] This application provides a possible implementation, in which the battery accessory includes an NFC chip or identification code storing encrypted information; and the terminal includes a second NFC card reader.

[0120] Obtain and decrypt encrypted information from battery accessories:

[0121] By reading the NFC chip of the battery accessory using a second NFC reader, the encrypted information of the battery accessory stored in the NFC chip can be obtained; or

[0122] Scan the identification code to obtain encrypted information about the battery accessories.

[0123] The battery accessory in this application embodiment includes an NFC chip that stores encrypted information, or an identity code that records encrypted information (the identity code can be located on the casing of the battery accessory). The identity code can be a QR code, or a barcode, a 3D code, or a numerical sequence code, etc. The terminal can include a second NFC card reader and a camera for scanning the identity code.

[0124] If the battery accessory includes an NFC chip, the terminal can perform an "NFC tap" on the NFC chip in the battery accessory after entering the "Accessory Authentication" page (when performing an NFC tap, the distance between the second NFC reader and the NFC chip is less than a preset distance threshold), so that the second NFC reader can read the encrypted information in the NFC chip.

[0125] If the battery accessory includes an identification code, the terminal can scan and identify the identification code containing encrypted information by using the "scan" function after entering the "Accessory Authentication" page, and obtain the encrypted information.

[0126] In a particular implementation scenario, the battery accessory of this application embodiment is a lithium battery carrying an NFC chip, such as... Figure 5As shown, this example illustrates a system architecture diagram for implementing the method for authenticating the battery accessories of a smart lock provided in this application embodiment when the battery accessory is a lithium battery carrying an NFC chip and the terminal is a mobile phone terminal.

The smart lock 510 and the mobile terminal 530 can perform an "NFC tap" to each other, allowing the mobile terminal 530 to read the encrypted information in the NFC chip of the lithium battery 520. The smart lock 510 can also perform an "NFC tap" to the lithium battery 520, allowing the smart lock 510 to read the encrypted information in the NFC chip of the lithium battery 520. The smart lock 510 and the mobile terminal 530 can communicate via Bluetooth. The mobile terminal 530 and the IoT platform 540 can communicate via network transmission (i.e., via the HTTP protocol). The IoT platform 540 and the accessory management platform 550 can also communicate via network transmission.

[0127] In a specific implementation scenario, the battery accessory in this application embodiment is a lithium battery carrying an identification code (e.g., a QR code). Figure 6 As shown, this example illustrates a system architecture diagram for implementing the method for authenticating the authenticity of battery accessories for smart locks provided in this application embodiment when the battery accessory is a lithium battery carrying an identification code and the terminal is a mobile phone terminal. The system includes a smart lock 610, a lithium battery 620, a mobile phone terminal 630, an IoT platform 640, and an accessory management platform 650. The lithium battery 620 is installed in the smart lock 610 and includes an identification code 621. The mobile phone terminal 630 has a "scan" function, which allows it to scan the identification code 621 in the lithium battery 620. The smart lock 610 and the mobile phone terminal 630 can communicate via Bluetooth. The mobile phone terminal 630 and the IoT platform 640 communicate via network transmission (i.e., via the HTTP protocol). The IoT platform 640 and the accessory management platform 650 also communicate via network transmission.

[0128] In one scenario, the battery accessory is a lithium battery, which includes an NFC chip or identification code storing encrypted information, and the terminal is a mobile phone terminal, such as... Figure 7As shown, it exemplarily illustrates the interaction flowchart between a smart lock, a lithium battery, a terminal, an IoT platform, and an accessory management platform, including: Step 1, the smart lock responds to the installation of a battery accessory to be authenticated on the smart lock; Step 2, a first authentication request is sent to the terminal bound to the smart lock; the first authentication request is used to instruct the acquisition and decryption of the encrypted information of the battery accessory; Step 3, the terminal responds to the first authentication request and acquires the encrypted information; Step 3 includes Step 3.1 or Step 3.2, Step 3.1 The terminal reads the encrypted information in the NFC chip of the lithium battery through "NFC tap-to-read," the encrypted information being obtained by encrypting battery information with a first key; Step 3.2 The terminal scans the identity code to obtain the encrypted information; Step 4: The mobile terminal sends a key acquisition request to the IoT platform; the key acquisition request is used to obtain the first key. Step 5: The IoT platform forwards the key acquisition request to the accessory management platform. Step 6: The accessory management platform sends the first key to the IoT platform. Step 7: The IoT platform encrypts the first key using the private key from a preset key pair. Step 8: The IoT platform sends the encrypted first key to the receiving mobile terminal. Step 9: The mobile terminal decrypts the encrypted first key using the private key from the preset key pair to obtain the first key. Step 10: The mobile terminal decrypts the encrypted information using the first key to obtain the accessory identifier of the battery accessory. Step 11: The mobile terminal sends a second authentication request containing the accessory identifier to the IoT platform. The IoT platform; the second authentication request is used to instruct the battery accessory to be authenticated based on the accessory identifier; step 12, the IoT platform forwards the second authentication request to the accessory management platform; step 13, the accessory management platform authenticates the battery accessory based on the accessory identifier, and obtains a first authentication result or a second authentication result, where the first authentication result indicates that the battery accessory has passed authentication; the second authentication result indicates that the battery accessory has failed authentication; step 14, the accessory management platform sends the first authentication result or the second authentication result to the IoT platform; the IoT platform executes step 15.1 or step 15.3, where in step 15.1, if the IoT platform determines that the smart lock is not connected to the Internet, it transmits the first authentication result or the second authentication result over the network. In step 15.2, the terminal sends the first authentication result or the second authentication result to the smart lock via Bluetooth. In step 15.3, the IoT platform determines that the smart lock is connected to the Internet and sends the first authentication result or the second authentication result to the smart lock via network transmission. The smart lock executes either step 16.1 or step 16.2. In step 16.1, if the smart lock receives the first authentication result, it displays a first message and writes the accessory identifier carried in the first authentication result into the MCU unit of the smart lock. The first message indicates that the battery accessory authentication is successful. In step 16.2, if the smart lock receives the second authentication result, it displays a second message. The second message indicates that the battery accessory authentication is unsuccessful and instructs the user to replace the battery accessory.

[0129] This application provides another method for authenticating the authenticity of battery accessories for smart locks, applied to a cloud platform, such as... Figure 8 As shown, the method includes:

[0130] Step S801: Receive a second authentication request sent by a terminal bound to the smart lock. The second authentication request is generated by the terminal after obtaining and decrypting the encrypted information of the battery accessory to be authenticated and obtaining the accessory identifier of the battery accessory. The second authentication request carries the accessory identifier. The second authentication request is used to instruct the cloud platform to perform authenticity authentication of the battery accessory based on the accessory identifier. The battery accessory to be authenticated is installed in the smart lock.

[0131] Step S802: Authenticate the battery accessory based on its accessory identification.

[0132] Step S803: If the battery accessory certification is confirmed to be successful, a first certification result is sent to the smart door lock. The first certification result indicates that the battery accessory certification is successful.

[0133] In this embodiment, the battery accessory is installed in a smart door lock. After detecting the installation operation of the battery accessory, the smart door lock generates and sends a first authentication request to the terminal in response to the installation operation. The first authentication request is used to instruct the acquisition and decryption of the encrypted information of the battery accessory. In response to the first authentication request, the terminal acquires and decrypts the encrypted information of the battery accessory to obtain the accessory identifier of the battery accessory, and generates a second authentication request carrying the accessory identifier. The second authentication request is sent to the cloud platform of the battery accessory, and is used to instruct the authenticity authentication of the battery accessory based on the accessory identifier.

[0134] Upon receiving the second authentication request, the cloud platform verifies the authenticity of the battery accessory based on its accessory identifier. The cloud platform includes an IoT platform and an accessory management platform. The IoT platform receives the second authentication request and forwards it to the accessory management platform. Upon receiving the second authentication request, the accessory management platform verifies the authenticity of the battery accessory based on the accessory identifier within the request.

[0135] Specifically, the accessory management platform in this application includes a target data table, which is used to record the accessory identifiers of qualified battery accessories. If the battery information of a battery accessory is successfully burned, the accessory management platform will contain the accessory identifier of the battery accessory.

[0136] Upon receiving the second certification request, the accessory management platform determines whether the accessory identifier in the second certification request is recorded in the target data table. If the accessory identifier is recorded in the target data table, a first certification result indicating that the battery accessory certification is qualified is generated; if the accessory identifier is not recorded in the target data table, a second certification result indicating that the battery accessory certification is unqualified is generated.

[0137] This application embodiment uses the interaction between the terminal, the IoT platform of the battery accessory, and the accessory management platform of the battery accessory to authenticate the authenticity of the battery accessory installed in the smart lock. This prevents the smart lock from being installed with counterfeit batteries, which could cause the smart lock to frequently go offline, be unable to connect to the network, fail to unlock using the electronic unlocking method, accidentally trigger the power alarm, or even burn out the lock during subsequent use, thus improving the user experience of using the smart lock.

[0138] This application provides a possible implementation method, in which the cloud platform includes an Internet of Things platform and an accessory management platform;

[0142] The parts management platform sends the first authentication result to the IoT platform;

[0143] If the IoT platform determines that the smart lock is connected to the Internet, it will send the first authentication result to the smart lock via network transmission.

[0144] If the IoT platform determines that the smart lock is not connected to the Internet, it will send the first authentication result to the terminal via network transmission and instruct the terminal to send the first authentication result to the smart lock via Bluetooth.

[0145] After obtaining the first or second authentication result, the accessory management platform sends the first or second authentication result to the IoT platform. The IoT platform determines whether the smart lock is connected to the Internet. If the smart lock is connected to the Internet, the IoT platform directly sends the first or second authentication result to the smart lock via network transmission. If the smart lock is not connected to the Internet, the IoT platform sends the first or second authentication result to the terminal, instructing the terminal to send the first or second authentication result to the smart lock via Bluetooth.

[0146] This application provides a possible implementation method, in which the cloud platform includes an Internet of Things (IoT) platform and an accessory management platform; the IoT platform stores the private key in a preset key pair; the accessory management platform stores a first key; the encrypted information is generated by encrypting the accessory identifier using the first key; and the terminal stores the public key in the preset key pair.

[0148] The IoT platform receives a key acquisition request sent by the terminal and forwards the key acquisition request to the parts management platform. The key acquisition request is used to obtain the first key.

[0149] In response to the key acquisition request, the parts management platform sends the first key to the IoT platform;

[0150] The IoT platform encrypts the first key using its private key to obtain the encrypted first key, and sends the encrypted first key to the terminal so that the terminal can decrypt the encrypted first key based on the public key to obtain the first key.

[0151] In this embodiment, a preset key pair is generated using a preset asymmetric encryption algorithm. The IoT platform stores the private key of the preset key pair, and the terminal stores the public key of the preset key pair. After receiving a key acquisition request from the terminal, the IoT platform forwards the key acquisition request to the parts management platform. The parts management platform stores a first key, and the key acquisition request is used to acquire the first key. The first key is a symmetric key generated using a symmetric encryption algorithm.

[0152] In response to the key acquisition request, the parts management platform sends the first key to the IoT platform. After receiving the first key, the IoT platform, in order to prevent the first key from being leaked, encrypts the first key using the private key in its own preset key pair to obtain the encrypted first key, and then sends the encrypted first key to the terminal.

[0153] In this embodiment of the application, the terminal stores the public key of a preset key pair. After receiving the encrypted first key, the terminal decrypts the encrypted first key using the public key to obtain the first key.

[0158] The accessory management platform 932 is used to authenticate the battery accessory 940 based on its accessory identifier. If the battery accessory 940 is found to be successfully authenticated, a first authentication result is generated and sent to the smart door lock 910 through the Internet of Things platform 931. The first authentication result indicates that the battery accessory 940 has been successfully authenticated.

[0159] The accessory management platform 932 is also used to generate a second certification result if it is determined that the battery accessory 940 has failed certification, and send the second certification result to the smart door lock 910 through the Internet of Things platform 931; the second certification result indicates that the battery accessory 940 has failed certification.
