DETAILED DESCRIPTION

[0072] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0073] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein, for example, can be implemented in an order other than those illustrated or described herein.

[0074] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0075] In the information security industry, ensuring data security and preventing unauthorized access are core tasks. In the face of the development and testing of terminal devices that are not connected to the Internet, information security professionals have adopted advanced methods such as dynamic passwords and multi-factor authentication to enhance system security protection and effectively prevent unauthorized access and data leakage.

[0076] In order to prevent information leakage, local password protection is usually used to limit access to non-networked devices. However, fixed passwords are at risk of being leaked. If local passwords are obtained by competitors, product confidential data will be leaked, bringing data security risks.

[0077] Therefore, how to solve the risk of data leakage caused by logging into non-internet-connected devices with fixed passwords is the problem that needs to be solved at present.

[0078] In response to the above problems, the present application provides a device login method for a non-networked device. The method obtains the identification information of the non-networked device through the login device and sets the validity period to form an original string; the string is transcoded into a QR code and sent to the password management device for parsing and security verification; after the verification is successful, a dynamic password is generated and fed back to the login device, so as to log in to the non-networked device, thereby enhancing the security of logging in to the non-networked device.

[0079] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0080] Figure 1 Signaling interaction of the device login method for the non-networked device provided in this embodiment Figure 1 This embodiment aims to explain the steps between the login device and the password management device when logging in to a device without an Internet connection. Figure 1 As shown, the device login method for a non-networked device provided in this embodiment includes:

[0081] S101. A login device obtains identification information of a non-networked device, and sets a validity period for the identification information to obtain an original character string corresponding to the non-networked device.

[0082] The login device obtains the identification information of the offline device by some means, such as scanning, inputting or automatic detection. The identification information is usually a unique device ID serial number or MAC address.

[0083] By obtaining the identification information of the offline device, it is ensured that each offline device has a identifiable identity, and different offline devices can be distinguished to avoid confusion.

[0084] The login device sets a validity range for the identification information of the non-networked device according to preset rules, such as a fixed time period, a specific date, etc. The validity range defines the time period during which the identification information is valid. The starting point of the validity period is the moment when the identification information is obtained.

[0085] By setting a validity period, the timeliness of the use of identification information can be limited, thereby increasing security and preventing expired or stolen identification information from being misused.

[0086] According to the acquired identification information and the set validity period, the login device combines the identification information and the validity period to form an original string. Specifically, the original string includes the device ID, the start time and the end time information of the validity period.

[0087] By setting an expiration date, you can limit the usage time of identification information and reduce the risk window after information leakage. The expiration date setting means that only legitimate access requests within a short period of time can be accepted, which enhances access control for devices without Internet access.

[0088] S102. The login device transcodes the original string to obtain a QR code corresponding to the original string.

[0089] The original character string is preprocessed as necessary, for example, unnecessary characters are removed, the format is standardized, etc., to ensure that the data format meets the requirements of QR code transcoding.

[0090] Select an appropriate encoding method to ensure that all characters in the original string can be processed correctly. Log in to the device to transcode the original string and obtain the QR code corresponding to the original string.

[0091] By transcoding the original string, a QR code corresponding to the original string can be generated based on the original string. The QR code is designed for fast scanning, which improves the efficiency of data input. This makes the transmission of information more efficient and secure.

[0092] S103. The login device sends the QR code to the password management device.

[0093] S104: The password management device parses the QR code to obtain a corresponding original string, where the original string is used to indicate identification information and validity period of the non-networked device.

[0094] The password management device scans the QR code sent by the login device, captures the QR code image and starts the parsing process, parses the QR code image, extracts the black and white modules, identifies the positioning pattern, timing pattern and format information, extracts the data module from the QR code based on the positioning and timing patterns, and converts it into the corresponding original string. Analyze specific fields in the original string to determine the identification information and validity period of the non-networked device.

[0095] The password management device effectively parses the information in the QR code. The automated QR code parsing reduces the need for manual input and reduces operational errors. The high fault tolerance of the QR code ensures that data can be accurately obtained even under unfavorable scanning conditions.

[0096] S105. The password management device performs security verification on the QR code based on the validity period and identification information.

[0097] The password management device splits the original string into two parts: identification information and validity period, so as to perform independent security verification. Check whether the identification information exists in the security identification list to ensure that the identification information of the non-networked device has been pre-authorized to prevent unauthorized devices from attempting to access the system. Compare the current time with the validity period to determine whether the current time is within the valid access period of the identification information, ensuring that the non-networked device can only be accessed within the validity period, thereby improving security.

[0098] Based on the validity of the identification information and whether the current time is within the valid access period, a comprehensive judgment is made to determine the security of the QR code, ensuring that only verified QR codes can be used to log in to devices without an Internet connection.

[0099] The password management device can ensure that only legitimate, authorized, and valid offline devices can access the device by performing security verification on the identification information and validity period in the QR code. This process improves the overall security of the system and reduces the risk of illegal access and data leakage. In this way, not only can offline devices be protected from the threat of unauthorized access, but the reliability and user experience of the entire system can also be improved.

[0100] S106. When the QR code verification passes, the password management device generates a dynamic password corresponding to the non-networked device.

[0101] The password management device receives a signal indicating that the QR code has been verified, confirming that the current access request is legitimate. If the QR code has been verified, the password management device uses a cryptographically secure random number generator to generate a random value. Specifically, the random number is combined with other possible variables such as timestamps, device IDs, etc., and a preset algorithm is applied to generate a dynamic password corresponding to the non-networked device.

[0102] The use of dynamic passwords significantly improves the security of the system because they are temporary and difficult to predict or reuse. Even if someone intercepts a dynamic password, it is difficult to use it for unauthorized access due to its short validity.

[0103] S107. The password management device feeds back the dynamic password to the login device.

[0104] S108: The login device performs a login process on the non-networked device based on the dynamic password.

[0105] Among them, the login device receives the dynamic password generated and transmitted by the password management device through a secure channel, and the login device performs login processing on the offline device based on the dynamic password. After receiving the input password, the offline device performs internal verification to confirm the correctness and validity of the password. If the password verification is successful, the offline device will authorize the login device to perform subsequent operations.

[0106] Use dynamic passwords to increase the security of the login process for devices without an Internet connection. Even if the device itself cannot connect to the Internet, it can still achieve relatively secure remote management and access control. This approach not only increases security, but also improves the user experience.

[0107] The present embodiment provides a device login method for a non-networked device, in which the login device obtains the identification information of the non-networked device and sets a validity period for the identification information to obtain an original character string corresponding to the non-networked device; the original character string is transcoded to obtain a QR code corresponding to the original character string, and the QR code is sent to a password management device; the password management device parses the QR code to obtain a corresponding original character string, where the original character string is used to indicate the identification information and validity period of the non-networked device; based on the validity period and the identification information, the QR code is security-verified; if the verification passes, a dynamic password is generated and fed back to the login device; so that the login device uses a dynamic password to log in to the non-networked device, thereby improving the security of the non-networked device login.

[0108] Figure 2 Signaling interaction of the device login method for the non-networked device provided in this embodiment Figure 2 .like Figure 2 As shown, this embodiment is in Figure 1 Based on the embodiment, the specific implementation process of the device login method for a non-networked device is described in detail. The device login method for a non-networked device provided in this embodiment includes:

[0109] S201. Log in to the device to obtain identification information of the non-networked device.

[0110] Among them, the login device needs to determine the type of identification information possessed by the non-networked device, such as a serial number, MAC address, device ID or other unique identifier.

[0111] According to the technical specifications and interfaces of the wireless device, select the appropriate method to obtain identification information, such as direct reading, scanning QR code, NFC sensing or serial communication.

[0112] The login device sends a request to the offline device to retrieve its identification information. After receiving the request, the offline device returns its identification information to the login device. The login device parses the data received from the offline device and extracts the identification information.

[0113] S202: The login device determines the validity period range corresponding to the identification information.

[0114] The login device determines the validity period rules of the identification information based on the device type, usage scenario or security requirements. The time when the identification information is obtained is set as the starting time of the valid access period, which is usually recorded by the system timestamp; according to the predefined rules, the duration of the validity period is set, which may be a few minutes, a few hours or longer; the duration is added to the starting time to determine the end time of the valid access period.

[0115] Determining the validity period corresponding to the identification information can effectively determine the validity period of the identification information of the wireless device, thereby ensuring that the wireless device can only be accessed within a specified time period. This not only improves security, but also enhances the controllability and flexibility of the system, which is very important for protecting wireless devices from unauthorized access.

[0116] S203: The login device generates an original character string according to the identification information and the validity period range.

[0117] Here, a structure of an original string is designed, which can contain all necessary information. Specifically, the structure of the original string contains device identification information, the start time and the end time of the validity period.

[0118] The login device encodes the device identification information in a predetermined format to ensure readability and consistency. The formatted validity period information is inserted to obtain the original string. Ensure that the generated original string contains both complete identification information and validity period range, and has good security and manageability. This helps protect non-networked devices from unauthorized access and ensures data integrity and consistency.

[0119] S204: The login device uses the encryption key to encrypt the original string to generate an encrypted string.

[0120] Among them, an encryption algorithm that meets the security requirements is selected, and the encryption key is determined by negotiation between the password management device and the login device. For example: AES, RSA or other industry standard encryption technologies. The login device uses the encryption algorithm and key to encrypt the original string and generate an encrypted string.

[0121] The original string is encrypted and becomes an encrypted string, ensuring the secure transmission and storage of data. The beneficial effects of this encryption method include improving data security, protecting sensitive information, and ensuring the integrity of data during transmission. At the same time, through the key negotiation mechanism, it can also ensure that only the legitimate recipient can decrypt the data, thereby increasing the security of the entire system.

[0122] S205. The login device transcodes the encrypted string to obtain a QR code.

[0123] Step S205 is similar to step S102 and will not be described again here.

[0124] S206. The login device sends the QR code to the password management device.

[0125] S207: The password management device transcodes the QR code to obtain an encrypted string corresponding to the QR code.

[0126] The password management device uses a QR code scanner or image recognition software to read the QR code image and extract the coded information therein. The scanned image is subjected to necessary image processing, such as denoising and contrast adjustment, to improve recognition accuracy. The password management device decodes the coded information in the QR code into the original string format and extracts the encrypted string from the decoded string.

[0127] S208. The password management device uses the decryption key to decrypt the encrypted string to obtain the corresponding original string.

[0128] The decryption key is determined by negotiation between the password management device and the login device. The password management device selects a corresponding decryption algorithm according to the encryption algorithm used in the encrypted string to perform decryption processing to obtain the corresponding original string. The original string is used to indicate the identification information and validity period of the non-networked device.

[0129] S209: The password management device determines whether there is a security identifier matching the identifier information in the security identifier list.

[0130] The password management device maintains a list of all valid security identifiers, each of which is associated with a specific offline device. The password management device searches for security identifiers that match the identifier information in the security identifier list, and determines whether there is a security identifier that matches the identifier information in the security identifier list.

[0131] Effectively determine whether there is a security identifier that matches the identification information in the security identifier list. This helps ensure the security of the system, prevent unauthorized access, and ensure normal access by legitimate users.

[0132] S210: When there is a security identifier matching the identifier information in the security identifier list, the password management device determines whether the current time is within the corresponding valid access period.

[0133] When there is a security identification matching the identification information in the security identification list, the password management device obtains the current system time, compares the current time with the extracted validity period information, and determines whether the current time is within the corresponding valid access period.

[0134] Determine whether the current moment is within the valid access period of the identification information. This helps ensure that the offline device can only be accessed within the specified time range, thereby improving the security of the system.

[0135] S211. When the current moment is within the corresponding valid access period, the password management device determines that the QR code security verification has passed.

[0136] If the current time is within the corresponding valid access period, the password management device determines that the QR code security check has passed. If there is no security identifier matching the identifier information in the security identifier list or the current time is not within the corresponding valid access period, the QR code security check has failed.

[0137] S212: When the QR code verification is passed, the password management device generates a dynamic password corresponding to the non-networked device.

[0138] The password management device receives the result of the QR code security verification. If the QR code verification passes, the password management device automatically triggers the dynamic password generation process. According to the pre-set password generation rules, a dynamic password corresponding to the non-networked device is generated.

[0139] S213. The password management device feeds back the dynamic password to the login device.

[0140] S214. The login device determines whether the moment of receiving the dynamic password is within a valid access period.

[0141] S215. When the dynamic password is received within the valid access period, the login device uses the dynamic password to log in to the non-networked device.

[0142] When the login device receives the dynamic password, it records the current specific time and verifies whether the time point of receiving the dynamic password is within the preset valid access period. If the dynamic password is received within the valid access period, the dynamic password is used to log in the non-networked device; if it is not within the valid access period, the login request is rejected.

[0143] The device login method for a non-networked device provided in this embodiment obtains the identification information and validity period of the non-networked device through the login device, and generates an original string based on this. After being encrypted with an encryption key, it is converted into a QR code and sent to the password management device. The latter parses and decrypts to verify the validity and time range of the identification information. After the verification is passed, a dynamic password is generated and fed back to the login device for logging in to the non-networked device, ensuring that the dynamic password is received within the validity period, thereby improving the security of logging in to the non-networked device and avoiding expired or malicious access attempts.
