The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the invention.
Reference is first made to fig. 1, which illustrates an application scenario in which embodiments of the present invention may be implemented.
The scenario shown in fig. 1 includes a terminal 100, a signature verification server 200, and an operation and maintenance system 300, where the terminal 100 may be a ticketing terminal and is provided with a confidential program, the signature verification server 200 is provided with a decryption interface, and the operation and maintenance system 300 is used by operation and maintenance personnel and may be used to query a password; the terminal 100, the signature verification server 200, and the operation and maintenance system 300 may be connected to each other through a mobile internet or the like.
For a ticketing terminal, operation and maintenance personnel need to maintain a terminal system regularly, and then a root password needs to be called. Since the root user is the only hypervisor in the system, it has the same authority as the operating system; the authority of the root user is enough to delete most files of the whole system, so that the system is completely destroyed and cannot be used again. Therefore, improper operation with root is quite dangerous, can be halted slightly, and can not even be started seriously. The root has all the authority of the system, if the root password is leaked, the whole computer is controlled by a person who steals the root password completely, and the possession of the root password means the possession of all the data of all the users on the computer. Therefore, the invention provides a method and a system for maintaining and managing the high-weight terminal password, which can realize the high-strength security protection of the large-scale high-weight terminal password and the key and ensure the security of the password and the key.

The terminal is a ticket selling terminal, the ticket selling terminal uses the same public key of the signature verification server, and the public key certificate of the signature verification server certificate is generated by a self-built PKI/CA system.
And step S2, the terminal encrypts the root password by using the public key of the signature verification server certificate and an asymmetric encryption algorithm to obtain the encrypted password. After the root password is encrypted by using the SM2 asymmetric encryption algorithm, the password security can be improved.
And step S3, uploading and storing the encrypted password to a operation and maintenance database.
In an embodiment, the encrypted password may be uploaded and stored to the operation and maintenance database by using an SSL channel, so as to ensure the security of the data transmission process.
And step S4, when the password inquiry instruction is received, calling a decryption interface of the signature verification server, decrypting the encrypted password by using the private key of the signature verification server, and acquiring the decrypted password.
And step S5, after the decrypted password is obtained, the password can be used by operation and maintenance personnel, and the decrypted password is used for logging in the terminal for maintenance.

It should be noted that although several modules of the maintenance management system of the terminal high-rights password are mentioned in the above detailed description, such division is merely exemplary and not mandatory. Indeed, the features and functionality of two or more of the modules described above may be embodied in one module according to embodiments of the invention. Conversely, the features and functions of one module described above may be further divided into embodiments by a plurality of modules.
In an embodiment of the present invention, the present invention further provides a computer device 400, as shown in fig. 4, including a memory 410, a processor 420, and a computer program 430 stored on the memory 410 and executable on the processor 420, where the processor 420 executes the computer program 430 to implement a method for maintaining and managing a high-rights password of a terminal.
In an embodiment of the present invention, a computer-readable storage medium is further provided, where a computer program for executing the method for maintaining and managing a high-authority password of a terminal is stored in the computer-readable storage medium.
For a clearer explanation of the method and system for maintaining and managing the high-rights password of the terminal, a specific embodiment is described below, but it should be noted that the embodiment is only for better explaining the present invention and is not to be construed as an undue limitation on the present invention.
The first embodiment is as follows:
taking a large-scale ticketing terminal of a certain enterprise as an example, the ticketing terminal automatically acquires a signature and signature verification server certificate after being started, and a root password is encrypted by using a signature and signature verification server certificate public key of the ticketing terminal (all ticketing terminals use the same signature server public key).
The encryption mode can perform root password encryption through an SM2 asymmetric encryption algorithm, and encryption and decryption utilize a public key and a private key of a signature verification server, wherein a public key certificate is generated and issued by a self-built PKI/CA system.
It should be noted that, in the prior art, the signature verification server is only used for signature verification of ticketing, but the root password is encrypted by using the signature verification server.
Among these, the SM2 asymmetric cryptographic algorithm requires two keys: the public key and the private key are a pair, and if the public key is used for encrypting data, only the corresponding private key can be used for decrypting the data; if the data is encrypted with a private key, it can only be decrypted with the corresponding public key. Since encryption and decryption use two different keys, an asymmetric encryption algorithm is used.
In the PKI/CA system, the PKI technology is the core of the information security technology, and the basic technologies include encryption, digital signature, data integrity mechanism, digital envelope, double digital signature, and the like. A typical, complete, and efficient PKI application system should have at least the following: and managing public key password certificates. Publishing and managing a blacklist; backup and recovery of keys; automatically updating the key; automatically managing a history key; cross-certification is supported. Certification Authority (CA): i.e., the issuing and applying authorities of digital certificates, the CA must be authoritative.
Further, the encrypted password is uploaded through an SSL channel and stored in the operation and maintenance database. The SSL channel is used for guaranteeing the safety of data transmission on the Internet, and the data Encryption (Encryption) technology is utilized to ensure that the data cannot be intercepted and intercepted in the transmission process on the network.
In asymmetric encryption, different keys are used for encryption and decryption, one key is used as a public key, and the other key is used as a private key. The public key encrypted information can be decrypted only by the private key. The private key can decrypt the encrypted information only by the public key. The private key is kept securely by the signature verification server and cannot be revealed, while the public key can be issued to anyone requesting it. Asymmetric encryption uses one of the pair of keys for encryption, while decryption requires the other key. The encryption mode has the advantages that the security is higher, the public key is public, the secret key is stored by the secret key, and the private key does not need to be sent to other people. Compared with a symmetric encryption algorithm, the asymmetric encryption algorithm has a lower speed than the symmetric encryption algorithm, so that the algorithm is only suitable for encrypting a small amount of data. However, the root password is only an 8-bit string, and the additional time of adopting the asymmetric encryption algorithm cannot influence the system starting efficiency.
And storing the encrypted ciphertext password in the operation and maintenance background database, calling a decryption interface of the signature verification server through the operation and maintenance system when the ticket terminal needs to be logged in, further decrypting the password by using a private key of the signature verification server, and inquiring to obtain a password plaintext for operation and maintenance personnel to use.
In summary, the terminal high-weight account password is encrypted by an asymmetric encryption algorithm, the asymmetric encryption algorithm is implemented by using a public key and a private key of a digital certificate, and the public key certificate is issued by a certificate authority. The password security is higher. The private key is generated through fixed equipment, cannot be extracted and exported after being generated, and high-strength secret key protection is carried out. The high-right account password is encrypted through TLS in the transmission process, and the safety of the data transmission process is guaranteed.
The method and the system for maintaining and managing the terminal high-weight password, provided by the invention, adopt an asymmetric encryption algorithm to carry out password encryption, and encryption and decryption utilize a public key and a private key of a signature verification server, so that high-strength confidentiality protection of the large-scale terminal high-weight password and the secret key is realized, and the safety of the password and the secret key is ensured.
While the spirit and principles of the invention have been described with reference to several particular embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, nor is the division of aspects, which is for convenience only as the features in such aspects may not be combined to benefit. The invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
