DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0019] The following, in conjunction with the accompanying drawings, describes in detail the quantum key injection method, device, electronic device and storage medium provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0020] Figure 1A quantum key injection method provided by an embodiment of the present invention is shown, and the method is applied to a card application that can be executed by a SIM card of an electronic device, and the electronic device may include: a server and / or a terminal device, wherein the terminal device may be, for example, a vehicle-mounted terminal or a mobile phone terminal. The method includes the following steps: S102: Receive a quantum key application request sent by a terminal device, and generate a first text message based on the quantum key application request.

[0021] In actual applications, when a terminal device needs to obtain a new quantum key, it will actively send a quantum key application request to the card application of the SIM card to obtain the quantum key it needs.

[0022] Specifically, the SIM card may be a smart card that supports the ISO / IEC 7816-4 specification and the 3GPP TS 31.111 specification, and specifically supports the Application Protocol Data Unit (APDU) instruction and the connection-oriented Bearer Independent Protocol (BIP).

[0023] S104: Send a first SMS message to a SMS gateway, so that the SMS gateway generates a second SMS message based on the received first SMS message and the first mobile phone number information, and sends the second SMS message to the quantum security service platform.

[0024] Among them, the first mobile phone number information is the mobile phone number information corresponding to sending the first text message.

[0025] In actual applications, when the SMS gateway receives the first SMS, it will also receive the mobile phone number (first mobile phone number information) of the SIM card that sent the SMS by default. It should be noted that, compared with the second mobile phone number information in the application data packet of the first SMS, the first mobile phone number information can be outside the application data packet.

[0026] S106: Receive a third SMS message including quantum key information sent by the SMS gateway, and extract the quantum key from the quantum key information in the third SMS message to inject the quantum key into the terminal device.

[0027] Among them, the quantum key is generated by the quantum security service platform based on the second SMS and sent to the SMS gateway.

[0028] Specifically, the quantum key information is information obtained by encrypting the quantum key in ciphertext form. The quantum key may include one or more of a quantum key user key, a quantum key user key detail, a quantum key device key, a quantum key device key detail, a quantum key application key, a quantum key application key detail, a quantum key session key, and a quantum key session key detail. Accordingly, the card application may parse the third SMS to obtain the quantum key information, and decrypt the quantum key information using the decryption algorithm built into the SIM card, thereby extracting the quantum key.

[0029] like Figure 2 As shown, the quantum key filling system of this embodiment may include a quantum security service platform, a short message gateway and a terminal device, wherein the terminal device includes a SIM card, and the SIM card includes the above-mentioned card application. Specifically, the quantum security service platform generates a quantum key based on the second short message, and can distribute the quantum key to the short message gateway through the quantum key distribution protocol. The short message gateway receives the short message request (first short message) from the terminal device, and can send the information (third short message) responded by the quantum security service platform to the terminal device. The terminal device can interact with the short message gateway and the SIM card, and is a data "transfer station" between the short message gateway and the SIM card.

[0030] In practical applications, the quantum key can be loaded into the terminal device, or it can be loaded into the SIM card of the terminal device, so that the user can subsequently use the quantum key for encrypted communication or authentication.

[0031] The quantum key charging method provided by the embodiment of the present invention receives a quantum key application request sent by a terminal device through a card application of a SIM card, and generates a first text message based on the quantum key application request; then, sends the first text message to a text message gateway, so that the text message gateway generates a second text message based on the received first text message and the first mobile phone number information, and sends the second text message to a quantum security service platform; wherein the first mobile phone number information is the mobile phone number information corresponding to the sending of the first text message; then receives a third text message including quantum key information sent by the text message gateway, and extracts the quantum key from the quantum key information of the third text message, so as to charge the quantum key to the terminal device; wherein the quantum key is generated by the quantum security service platform based on the second text message and sent to the text message gateway. Compared with related quantum key charging technologies, this solution is based on SIM cards and SMS gateways, and performs online charging of quantum keys in the form of SMS. It does not require human intervention to complete the physical transfer of keys from the quantum key management center to each terminal device, which is more efficient and low-cost. At the same time, it reduces the risk of unauthorized access, tampering, loss or theft of quantum keys during circulation, and improves security. In addition, this charging method expands the channels for obtaining quantum keys. Users do not need to go to specific locations in person or go through complicated processes. Users only need to complete key charging through simple SMS operations, which improves user experience and solves the problem of insufficient flexibility of related quantum key charging technologies due to time and location limitations.

[0032] In one implementation, based on the quantum key application request, generating a first text message (i.e., S102) can be specifically performed as follows: Steps A1 to A2: Step A1, generate first quantum key application information according to the quantum key application request, and obtain first card information.

[0033] The first card information includes the second mobile phone number information.

[0034] Step A2, generating a first text message according to the first quantum key application information and the first card information.

[0035] Among them, the second mobile phone number information is used for the quantum security service platform to receive the second text message, perform a first verification on the second text message based on the first mobile phone number information and the second mobile phone number information in the second text message, and generate a quantum key based on the second text message if the first verification passes; the first verification includes verifying whether the first mobile phone number information and the second mobile phone number information in the second text message are consistent.

[0036] In this embodiment, a first verification is performed on the second text message through the quantum security service platform to determine whether the second text message is credible. If the second text message passes the first verification, the second text message is considered to be credible, and a corresponding quantum key is generated, thereby ensuring the security of the quantum key.

[0037] In one implementation, the third text message also includes the second card information; the first quantum key application information includes the quantum key type information. Before extracting the quantum key from the quantum key information of the third text message (ie, S106), the following step B1 may be performed to determine whether the third text message is credible: Step B1: Based on the first text message, perform a second verification on the third text message.

[0038] The second check includes one or more of the following: Verify whether the quantum key type information corresponding to the quantum key information in the third short message is consistent with the quantum key type information in the first short message; Verify whether the second card information in the third text message is consistent with the first card information in the first text message.

[0039] Exemplarily, as shown in FIG3 (a), the structure of the third SMS may include an SMS message header, an application command security field, and an application command message; as shown in FIG3 (b), the application command message may include a message authentication code (MAC), a card application main version number MAIN-VER, an encryption identifier Flag, and application data; wherein the application data may include tag information, quantum key total space information, the above quantum key information, and second card information; wherein the field definitions of the tag information and the above quantum key information may be as shown in Table 1 below: Table 1

[0040] Exemplarily, the quantum key application request sent by the terminal device is a request for a quantum key session key, and the card application generates a corresponding first SMS based on the quantum key application request; correspondingly, when receiving the third SMS, the card application verifies whether the quantum key type information corresponding to the second quantum key information in the third SMS is the quantum key session key type (the quantum key type information in the first SMS). Of course, the application data may also include the second quantum key application information, and the second verification may also include verifying whether the second quantum key application information in the third SMS is consistent with the first quantum key application information in the first SMS.

[0041] Correspondingly, extracting the quantum key from the quantum key information of the third short message (ie, S106) can be specifically performed as follows: step B2: Step B2, when the second verification is passed, extract the quantum key from the quantum key information of the third SMS and store the quantum key in the SIM card.

[0042] Specifically, the SIM card may be a common SIM card or a super SIM card.

[0043] In this embodiment, the card application performs a second verification on the received response information (third SMS) to verify whether it is the response information corresponding to the SMS application (first SMS) sent by the card application, thereby ensuring that the received quantum key is safe and reliable, and further, the received quantum key is stored in the SIM card to reduce the possibility of tampering and theft of the quantum key, thereby increasing the security of the quantum key.

[0044] In one implementation, the above-mentioned first card information also includes first SIM card identification information; the first SIM card identification information is used by the quantum security service platform to determine whether there is target binding information representing the binding of the first mobile phone number information and the first SIM card identification information in the binding information stored by the quantum security service platform, and if there is no target binding information, a binding relationship is established between the first mobile phone number information and the first SIM card identification information.

[0045] In actual applications, when there is no target binding information, the quantum security service platform can establish a binding relationship between the first mobile phone number information and the first SIM card identification information, and then the quantum security service platform generates a quantum key to be used in the background to associate the binding information with the quantum key; when there is target binding information, the quantum security service platform can generate a quantum key. Specifically, when there is no target binding information, it can be determined whether there is binding information corresponding to the first mobile phone number information or binding information corresponding to the first SIM card identification information in the binding information; when the binding information corresponding to the first mobile phone number information does not exist and the binding information corresponding to the first SIM card identification information does not exist, the first mobile phone number information is established with the first SIM card identification information; then, the quantum security service platform generates a quantum key, so that when the second SMS (at least including the first quantum key application information, the first SIM card identification information, the first mobile phone number information and the second mobile phone number information) is credible, the quantum key is generated to send the quantum key to the SMS gateway (in the form of SMS) that sends the second SMS, thereby ensuring the security of the quantum key.

[0046] In this embodiment, the structure of the second SMS is designed to include the information required for binding (the first mobile phone number information and the first SIM card identification information), so that binding can be performed quickly and conveniently.

[0047] In one implementation, the first SMS includes a message authentication code (MAC) and an application data packet. According to the first quantum key application information and the first card information, the first SMS is generated (i.e., step A2), which can be specifically performed as follows: steps C1 to C3: Step C1, generating an application data packet based on the first quantum key application information and the first card information.

[0048] Step C2, generating a MAC based on a preset symmetric encryption algorithm and an application data packet.

[0049] Step C3, generating a first SMS based on the MAC and application data packet.

[0050] Among them, MAC is used by the SMS gateway to perform security verification on the received first SMS based on a preset symmetric encryption algorithm.

[0051] Specifically, the preset symmetric encryption algorithm may be an SM4 CBC algorithm, that is, a method of constructing a MAC based on the SM4 algorithm using a Cipher Block Chaining (CBC) mode. Each plaintext block is XORed with the previous ciphertext block before encryption. This method can effectively hide plaintext data.

[0052] Exemplarily, as shown in FIG4(a), the structure of the first SMS may include an uplink message header, an SMS security field, and a response data packet; the response data packet includes at least a MAC and the above-mentioned application data packet, specifically, as shown in FIG4(b), the corresponding field definition of the response data packet may be as shown in Table 2 below: Table 2

[0053] The first card information and the second card information may further include one or more of the second mobile phone number length and the SIM card identification information length; the first quantum key application information may further include quantum key storage space information. The SIM card identification information may include, for example, a security element identifier (SEID).

[0054] In this embodiment, the received first SMS is securely verified and forwarded through the SMS gateway, so that the quantum key application information can be securely and reliably transmitted to the quantum security service platform, providing necessary support for the subsequent quantum key generation and distribution process.

[0055] Corresponding to the above Figure 1Based on the same technical concept as the quantum key injection method for the card application of the SIM card described in FIG. 4 , the embodiment of the present application also provides a quantum key injection method for the quantum security service platform. Figure 5 A flowchart of a quantum key injection method provided in an embodiment of the present application is provided. The method can be executed by a quantum security service platform, wherein the quantum security service platform may include: a server and / or a terminal device, wherein the terminal device may be, for example, a vehicle-mounted terminal or a mobile phone terminal. In other words, the method can be executed by software or hardware installed on the quantum security service platform, and the method includes the following steps: S502: Receive a second SMS sent by the SMS gateway.

[0056] Among them, the second SMS is generated by the SMS gateway based on the received first SMS and the first mobile phone number information; the first SMS is generated by the SIM card application based on the quantum key application request sent by the terminal device; the first mobile phone number information is the mobile phone number information corresponding to the sending of the first SMS.

[0057] S504: Generate a quantum key based on the second SMS.

[0058] S506: Based on the quantum key, generate a fourth SMS including the quantum key, and send the fourth SMS to the SMS gateway, so that the SMS gateway generates a third SMS including the quantum key information based on the fourth SMS, and sends the third SMS to the SIM card.

[0059] Among them, the third SMS is used for the card application of the SIM card to extract the quantum key from the quantum key information of the third SMS to inject the quantum key into the terminal device.

[0060] Specifically, a fourth text message is generated according to the quantum key and the first mobile phone number information, and the fourth text message is sent to the text message gateway; the text message gateway generates a third text message including the quantum key information based on the fourth text message, and sends the third text message to the SIM card according to the first mobile phone number information in the fourth text message.

[0061] It should be noted that the process of the quantum key injection method from S502 to S506 can refer to the specific implementation process of the above embodiment, which will not be repeated here.

Compared with related quantum key charging technologies, this solution is based on SIM cards and SMS gateways, and performs online charging of quantum keys in the form of SMS. It does not require human intervention to complete the physical transfer of keys from the quantum key management center to each terminal device, which is more efficient and low-cost. At the same time, it reduces the risk of unauthorized access, tampering, loss or theft of quantum keys during circulation, and improves security. In addition, this charging method expands the channels for obtaining quantum keys. Users do not need to go to specific locations in person or go through complicated processes. Users only need to complete key charging through simple SMS operations, which improves user experience and solves the problem of insufficient flexibility of related quantum key charging technologies due to time and location limitations.

[0063] In one implementation, based on the second short message, generating a quantum key (i.e., S504) can be specifically performed as follows: Steps D1 to D2: Step D1, performing a first verification on the second text message based on the first mobile phone number information and the second mobile phone number information in the second text message.

[0064] Among them, the first card information includes the second mobile phone number information; the first card information is obtained by the card application and is used to generate a first text message based on the first quantum key application information and the first card information; the first quantum key application information is generated by the card application based on the quantum key application request.

[0065] Step D2, if the first verification passes, generating a quantum key based on the second SMS; The first verification includes verifying whether the first mobile phone number information and the second mobile phone number information in the second text message are consistent.

[0067] In one implementation, the first card information also includes the first SIM card identification information. Before generating the quantum key (ie, S504), the following steps E1 to E2 may also be performed: Step E1, determining whether there is target binding information representing the binding of the first mobile phone number information and the first SIM card identification information in the binding information stored in the quantum security service platform.

[0068] Step E2: if the target binding information does not exist, a binding relationship is established between the first mobile phone number information and the first SIM card identification information.

[0070] The process of the above-mentioned quantum key injection method applied to the quantum security service platform can refer to the specific implementation process of the quantum key injection method embodiment applied to the card application of the SIM card, which will not be repeated here.
