Abstract

The invention relates to a password authentication method and system, an electronic device and a storage medium, and the method comprises the steps: generating a first random number in response to a login request of a user; receiving a second random number, a salt value and a cycle number returned by the server, and generating a client authentication certificate; obtaining a signature abstract and a client signature based on the client authentication credential, and sending the client signature and the client authentication credential to a server for signature verification; and receiving a first server authentication certificate returned by the server, performing HMAC-SM3 calculation on a first key generated by the server in a registration stage, generating a second server authentication certificate, and authenticating the server successfully under the condition that the first server authentication certificate is consistent with the second server authentication certificate. Through the password authentication method and device, the problem that the password is easily attacked and leaked in a password authentication process in the prior art is solved, and password security authentication is realized.

Description

technical field [0001] The present application relates to the field of identity authentication, in particular to a password authentication method, system, electronic device and storage medium. Background technique [0002] Currently, many online transactions are protected by identity authentication technology, which is the basis of electronic payment. However, until now, incidents such as SMS verification code hijacking and account theft have continued to break out in various industries, resulting in asset transfers and loss of tens of millions of assets, which has sounded the alarm for all walks of life. Among them, password authentication is a relatively simple and easy identity authentication method commonly used by most application systems. However, attack methods such as dictionary attack, information interception / replay, and network data stream eavesdropping still seriously threaten the security of password authentication. [0003] Usually there are two types of passw...
