Technical Field

[0001] The present application relates to the technical field of equipment maintenance, and in particular to a login authentication method, device, computer equipment, medium and product for a Linux terminal. Background Art

[0002] As a key device for charging electric vehicles, charging piles run software and hardware components based on the embedded Linux system. These components work together to achieve functions such as charging control, data communication, and billing management. Linux terminals play a vital role in the maintenance of charging piles. They provide operators with an interface to interact directly with the charging pile system to perform key maintenance operations such as troubleshooting, system upgrades, and parameter configuration.

[0003] At present, when operation and maintenance personnel log in to the Linux terminal to perform equipment maintenance, they generally use the user name and password authentication method. In this method, after the equipment leaves the factory, the operation and maintenance personnel set the user name and password required to log in to the Linux terminal by themselves, and then use this user name and password to log in to the terminal to carry out equipment maintenance work.

[0004] However, the traditional authentication method has significant drawbacks in practical applications. When an operator leaves, the username and password of the charging pile must be updated for security reasons. At this time, the only way to update the username and password of the charging piles one by one is offline. Each charging pile needs to be operated separately, which is not only inefficient, but also prone to human errors during operation, affecting the normal operation and safety of the equipment. Summary of the invention

[0005] Based on this, it is necessary to provide a login authentication method, device, computer equipment, medium and product for a Linux terminal that can effectively ensure the security of device operation in response to the above technical problems.

[0010] In one embodiment, the step of generating a random number string according to a target string includes:

[0011] Identify the text content of the target string;

[0013] In one embodiment, the process of an operation and maintenance personnel inputting a random number string into a security authentication system includes:

[0014] When the operation and maintenance personnel triggers the login security authentication system, the login information entered by the operation and maintenance personnel is obtained;

[0015] When the login information is verified, the operation and maintenance personnel are prompted to enter a random number string.

[0016] In one embodiment, the step of obtaining the ciphertext generated by the security authentication system for the random digital string includes:

[0017] The random number string is encrypted with a private key through a security authentication system to obtain a corresponding ciphertext, and the ciphertext is displayed to an operation and maintenance personnel through the security authentication system to instruct the operation and maintenance personnel to input the ciphertext.

[0018] In one embodiment, the method further comprises:

[0019] If the ciphertext decryption fails or the decrypted string is inconsistent with the random number string, you are not allowed to log in to the Linux terminal.

[0020] In one embodiment, the method further comprises:

[0021] When the operation and maintenance personnel is out of the job, the login information of the operation and maintenance personnel is deleted from the security authentication system to determine that the login information of the operation and maintenance personnel has failed the authentication;

[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] The login authentication method of the Linux terminal provided in the embodiment of the present application can be applied in the application environment shown in Figure 1. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. Among them, the server 104 is deployed with a security authentication system. The terminal 102 is used to generate a random number string according to the target string when receiving the target string input by the operation and maintenance personnel, and obtain the ciphertext generated by the security authentication system for the random number string when the operation and maintenance personnel input the random number string into the security authentication system, and allow the login of the Linux terminal when the ciphertext is successfully decrypted and the decrypted string is consistent with the random number string. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices, and the Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head mounted device may be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The server 104 may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0039] In an exemplary embodiment, as shown in FIG2 , a login authentication method for a Linux terminal is provided, and the method is applied to the terminal 102 in FIG1 as an example for explanation, including the following steps 202 to 206. Among them:

[0040] S202: upon receiving a target character string input by an operation and maintenance personnel, generating a random number string according to the target character string.

[0041] Optionally, when the operator inputs a target string, the Linux terminal generates a random string of numbers based on the specific target string. The target string can be a specific code, password, or other string with a specific meaning pre-set by the operator, thereby providing a dynamic and unpredictable credential in the subsequent security authentication process. For example, the operator inputs a specific string "lotus" on the Linux terminal, and the Linux terminal generates a random string of numbers "12345678".

[0042] S204: When the operation and maintenance personnel input the random number string into the security authentication system, obtain the ciphertext generated by the security authentication system for the random number string.

[0043] Optionally, the operation and maintenance personnel input the generated random number string into the security authentication system. After receiving the random number string, the security authentication system will encrypt it and generate a ciphertext to ensure that even if the ciphertext is intercepted, it is difficult to crack and restore the original random number string. Among them, the security authentication system is deployed on the website of the server, and the operation and maintenance personnel have registered on the website. The operation and maintenance personnel can log in to the security authentication system through the registration information during registration.

[0044] S206: If the ciphertext is decrypted successfully and the decrypted character string is consistent with the random number string, logging into the Linux terminal is allowed.

[0045] Optionally, the Linux terminal decrypts the ciphertext returned by the security authentication system. If the decryption is successful and the decrypted string is consistent with the random number string generated previously, the operation and maintenance personnel are allowed to log in to the Linux terminal, ensuring that only users who have been properly authenticated can access the Linux terminal system, preventing unauthorized personnel from illegally logging in.

[0046] In the above-mentioned login authentication method for the Linux terminal, by generating a random number string and combining it with the encryption and decryption process of the security authentication system, the generation of the random number string makes the credentials for each login different, which can improve the security of the login, and the login is only allowed if the decryption is successful and the decrypted string is consistent with the random number string, which can effectively ensure the safety of equipment operation, avoid illegal login, and thus improve operation and maintenance efficiency.

[0047] In an exemplary embodiment, the step of generating a random number string based on a target character string includes: identifying the text content of the target character string; if the text content is verified, generating a random number of a preset length to obtain a random number string, and displaying the random number string to an operation and maintenance personnel.

[0048] Optionally, when the operation and maintenance personnel input the target string, the Linux terminal first needs to identify the text content of the target string, including parsing the format of the target string, character encoding, etc., to ensure accurate identification of the target string. After the text content of the target string is verified, the Linux terminal will generate a random number of a specific length according to the preset requirements, and display this random number string to the operation and maintenance personnel so that the operation and maintenance personnel can obtain the credentials for subsequent security authentication. Among them, the preset length is set to meet the requirements of the security authentication system or the login system. For example, a 6-digit random number string is generated.

[0049] In this embodiment, the dynamism of the login credentials is increased by generating a random number string based on the target character string. Since the random number string is associated with the target character string and is randomly generated, it is more difficult for attackers to predict the login credentials compared to the traditional fixed password login method, which can enhance the security of login authentication.

[0050] In an exemplary embodiment, the process of an operation and maintenance personnel inputting a random number string into a security authentication system includes: when the operation and maintenance personnel triggers a login to the security authentication system, obtaining the login information input by the operation and maintenance personnel; when the login information is verified, prompting the operation and maintenance personnel to enter a random number string.

[0051] Optionally, when the operator triggers the login security authentication system, the system first obtains the login information entered by the operator, where the login information usually includes a user name, password, or other content related to identity identification. The system verifies the login information, for example, checking whether the user name exists, whether the password is correct, or verifying other identity authentication factors. After the login information is verified, the system prompts the operator to enter a random number string for further security authentication to ensure the legitimacy of the login operation.

[0052] In this embodiment, the login information of the operation and maintenance personnel is verified by the security authentication system, which can prevent illegal users from logging into the internal system. Afterwards, by inputting a random number string into the security authentication system and encrypting it by the security authentication system, the security of the verification information can be ensured, thereby improving the reliability of the login authentication.

[0053] In an exemplary embodiment, obtaining the ciphertext generated by the security authentication system for the random number string includes: encrypting the random number string with a private key through the security authentication system to obtain the corresponding ciphertext, and displaying the ciphertext to the operation and maintenance personnel through the security authentication system to instruct the operation and maintenance personnel to input the ciphertext.

[0054] Optionally, the security authentication system uses a private key to encrypt the random number string input by the operation and maintenance personnel. In this process, the random number string is input into the security authentication system as plain text, and the encryption algorithm converts the random number string according to the private key and specific encryption rules. Afterwards, the security authentication system displays the generated ciphertext to the operation and maintenance personnel so that the operation and maintenance personnel can pass the ciphertext to the subsequent verification link for decryption and verification operations.

[0055] In this embodiment, a high degree of security can be provided by using a private key to encrypt a random number string. Only an authorized security authentication system possesses the private key, ensuring that only a legitimate system can perform encryption operations and preventing external attackers from forging the encryption process. The private key encryption based on the security authentication system makes the ciphertext closely related to the security authentication system and the operations of the operation and maintenance personnel. When the ciphertext is subsequently decrypted and verified, if the decryption is successful and as expected, the identity of the operation and maintenance personnel can be more reliably verified.

[0056] In an exemplary embodiment, the method further includes: if the ciphertext is not decrypted successfully or the decrypted character string is inconsistent with the random number string, logging into the Linux terminal is not allowed.

[0057] Optionally, when the operator inputs the ciphertext, the Linux terminal uses the matching public key to decrypt the ciphertext and compares the decrypted string with the previously generated random number string. If the decryption fails, it may be because the ciphertext has been tampered with during transmission, the encryption key does not match, or other security issues occur. If the decryption succeeds but the string obtained is inconsistent with the random number string, it may be that the ciphertext has been maliciously replaced or an error occurred during the generation or transmission process. If the ciphertext decryption fails or the decrypted string is inconsistent with the random number string, the operator is not allowed to log in to the Linux terminal.

[0058] In this embodiment, by not allowing login to the Linux terminal when the ciphertext decryption fails or the decrypted string is inconsistent with the random number string, the device operation security can be effectively guaranteed, illegal login can be avoided, and operation and maintenance efficiency can be improved.

[0059] In an exemplary embodiment, the method also includes: when the operation and maintenance personnel is away from their job, deleting the operation and maintenance personnel's login information from the security authentication system, and determining that the operation and maintenance personnel's login information verification fails; if the login information verification fails, logging into the Linux terminal is not allowed.

[0060] Optionally, when the operation and maintenance personnel is out of the job, their login information is deleted from the security authentication system, ensuring that the identity of the operation and maintenance personnel in the system is removed, so that when the login verification is performed, their login information verification fails. Further, if the login information verification of the outgoing operation and maintenance personnel fails, they are not allowed to log in to the Linux terminal, thereby ensuring login security.

[0061] In this embodiment, by deleting the login information of the operation and maintenance personnel from the security authentication system when the operation and maintenance personnel is off-duty, the identity information of the operation and maintenance personnel can be managed in real time, thereby ensuring the real-time and reliability of login authentication.

[0062] In an exemplary embodiment, as shown in FIG3 , a login authentication method for a Linux terminal is provided, the method comprising the following steps:

[0063] S302: When receiving the target character string input by the operation and maintenance personnel, identify the text content of the target character string; when the text content is verified, generate a random number of a preset length to obtain a random number string, and display the random number string to the operation and maintenance personnel.

[0064] S304: When the operation and maintenance personnel triggers the login security authentication system, the login information input by the operation and maintenance personnel is obtained; when the login information is verified, the operation and maintenance personnel is prompted to enter a random number string.

[0065] S306: When the operation and maintenance personnel input the random number string into the security authentication system, the random number string is encrypted with a private key through the security authentication system to obtain a corresponding ciphertext, and the ciphertext is displayed to the operation and maintenance personnel through the security authentication system to instruct the operation and maintenance personnel to input the ciphertext.

[0066] S308: If the ciphertext is decrypted successfully and the decrypted character string is consistent with the random number string, logging into the Linux terminal is allowed.

[0067] S310: If the ciphertext decryption fails or the decrypted character string is inconsistent with the random number string, logging into the Linux terminal is not allowed.

[0068] S312: When the operation and maintenance personnel is in a resigned state, the login information of the operation and maintenance personnel is deleted from the security authentication system, and it is determined that the login information verification of the operation and maintenance personnel fails; when the login information verification fails, the user is not allowed to log in to the Linux terminal.

[0069] In this embodiment, by generating a random number string and combining it with the encryption and decryption process of the security authentication system, the generation of the random number string makes the credentials for each login different, which can improve the security of the login, and login is only allowed if the decryption is successful and the decrypted character string is consistent with the random number string, which can effectively ensure the safe operation of the equipment and avoid illegal login, thereby improving operation and maintenance efficiency.
