Abstract

The present invention provides a database multi-authentication method, system, terminal and storage medium, comprising: initializing the hardware authentication certificate carrier through a programming interface, and saving the public key of the hardware authentication certificate carrier and the public name of the user certificate; The public name is used as the database user name, and the standard information summary value of the database user name is generated; the authentication request sent by the client is received and the user certificate in the authentication request is verified, and the initial random number is returned to the client after passing the verification ; Receive the signed random number sent by the client, use the public key to decrypt the signed random number to obtain a random number; confirm that the random number is consistent with the initial random number, then obtain the information digest value of the client user name, If the information digest value of the user name of the client is consistent with the standard information digest value, it is determined that the client is authenticated. The invention increases the security of the database and the confidentiality of the user.

Description

technical field [0001] The invention relates to the technical field of database authentication, in particular to a database multiple authentication method, system, terminal and storage medium. Background technique [0002] With the continuous advancement of informatization, data security and business operation reliability are becoming more and more important. After completing the legal authentication of the user who logs in to the database, all information in the computer network world, including the user's identity information, is represented by a set of specific data. The computer can only identify the user's digital identity, and all authorizations for users are also directed to Authorization of the user's digital identity. [0003] How to ensure that the operator who operates with a digital identity is the legal owner of the digital identity, that is to say, to ensure that the operator's physical identity corresponds to the digital identity. Identity authentication is t...
