Database Multi-Authentication Method and System, Terminal, and Storage Medium

A terminal, comprising a memory and one or more processors, wherein the memory stores computer readable instructions, when executed by the processors, make the one or more processors to:

• initialize a hardware authentication certificate carrier by means of a programming interface, and store a public key of the hardware authentication certificate carrier and a user certificate public name;
• take the user certificate public name as a database user name, and generate a standard message digest value of the database user name;
• receive an authentication request sent from a client and verify a user certificate in the authentication request, and return an initial random number to the client after the verification is passed;
• and
• receive a signature random number sent from the client, and use the public key to decrypt the signature random number to obtain a random number;
• in response to determining that the random number is consistent with the initial random number, acquire a message digest value of a client user name, and in response to determining that the message digest value of the client user name is consistent with the standard message digest value, determine that the client passes the authentication.
