Problems solved by technology

[0004] Under the PKI system, users need to register the corresponding certificates with the CA in advance before communicating, and the CA stores the certificates in the certificate store, which makes the process of requesting to verify the user's identity cumbersome.
In the identity-based cryptographic system, the private key parser and the server are integrated, and the server's system private key is transparent, which poses hidden dangers to the user's information security

Embodiment 1

[0042] figure 1 It is a schematic flowchart of a method for generating a user key provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of generating a key, and the method can be executed by a user key generating device configured in a key parser . Such as figure 1 As shown, the method specifically includes the following steps:

[0043] Step 110: In response to the user's first key generation instruction, determine the user's first key according to the user registration information in the first key generation instruction and the server's first key.

[0044] Wherein, the user registers the user on the application side, and saves the user registration information in the server, wherein the user registration information may include a user account number and a user password. The key resolver responds to the first key generation instruction issued by the user on the application side, obtains the user registration information and the server'...

Embodiment 2

[0058] figure 2 It is a schematic flowchart of a method for generating a user key provided in Embodiment 2 of the present invention. This embodiment is further optimized on the basis of the above-mentioned embodiment. This method can be generated by the user key configured in the key resolver. device to execute. Such as figure 2 As shown, the method specifically includes the following steps:

[0059] Step 210: Determine the second key of the server according to the system parameters of the server, and store the second key of the server.

[0060] Wherein, the key resolver obtains system parameters stored in the server, and the key resolver can be divided into a trusted execution module and a trusted storage module. The trusted execution module is a module that obtains user registration information and server system parameters to calculate the key. The trusted storage module is a trusted execution environment that is used to store the second key of the server and ensure the...

Abstract

The embodiment of the invention discloses a user key generation method and device, equipment and a storage medium. The method is executed by a key parser, and comprises the following steps: in response to a first key generation instruction of a user, determining the first key of the user according to user registration information in the first key generation instruction and a first key of a server;in response to the second key generation instruction of the user, sending user registration information in the second key generation instruction to the server for auditing; and receiving an auditingresult of the user registration information fed back by the server, and if the auditing is passed, determining the second key of the user according to the second key of the server and the first key ofthe user. According to the embodiment of the invention, a key parser is adopted to determine the user key, and the server is used for auditing the user registration information, so that information leakage caused by overlarge authority of the key parser is avoided.

Description

technical field [0001] Embodiments of the present invention relate to computer communication and information security technologies, and in particular to a method, device, device and storage medium for generating a user key. Background technique [0002] With the development of information technology, information security has attracted more and more attention. When people exchange information, in order to avoid information leakage, they need to use their own private key to keep the information confidential. [0003] The technology widely used to ensure the security and integrity of information is called "PKI" (PublicKey Infrastructure, public key infrastructure), which needs to be bound by a trusted authority CA (CertificateAuthority, digital certificate authority) User public key and user identity information. It is also possible to use the identity-based cryptographic system to deduce the user's public key from the user's identity information, and then generate the user's...
