AI Technical Summary

Technical Problem

The prior art cannot effectively protect the security of user identity authentication in a public network environment, and accounts and passwords are easily cracked, resulting in information leakage and property losses.

Method used

Using the encryption method of multiple hashing and transformation operations, the client and the server perform four hashing and transformations respectively, and the encryption effect of one password at a time is achieved through additional codes to prevent login information from being listened to and cracked.

Benefits of technology

It improves the security of user identities in public network environments, prevents information leakage and property losses, reduces the success rate of brute-force cracking and database collisions, and improves the information security level.

Abstract

The invention discloses a security authentication method for user identity validity in a public network environment, which belongs to the technical field of information security and comprises the following steps: a client acquires an account input by a user, a password input by the user and an additional code sent by a server; hashing the password input by the user for the first time; performing conversion operation on the first hash result and an additional code; performing second hash on the first conversion result; sending the account input by the user and the second hash result to the server; the server obtains a password corresponding to the account based on the account input by the user; hashing the held password for the third time; performing conversion operation on the third hash result and the additional code, and performing fourth hash on the second conversion result; comparing whether the second hash result and the fourth hash result are the same or not; if yes, the user is allowed to log in normally, and if not, the user is refused to log in. According to the invention, a user login account and a password can be prevented from being cracked, so that user information leakage and property loss are prevented.
