Symmetric dynamic authentication and key exchange system and method thereof

摘要

A symmetric dynamic authentication and key exchange system and a method thereof are provided. A client and a server obtain initial authentication information at the same time, the client generates first one-time temporary authentication information, a conference key and a standby identity identifier according to the initial authentication information, and transmits them to the server, and the server performs a dynamic authentication program. The server compares the initial authentication information of the client with the conference key to confirm an identity of the client, and then updates the initial authentication information of the server according to the first one-time temporary authentication information, and the server is enabled to have the first one-time temporary authentication information the same as that of the client, and then to generate second one-time temporary authentication information including the standby identity identifier according to the first one-time temporary authentication information and the initial authentication information.
