AN AUTHENTICATION METHOD, SYSTEM, SERVER AND USER NODE

摘要

An authentication method, system, server and user node are disclosed, and the method comprises: the server generates a server session key according to identity information, logging information parameter and validity period in logging information, and generates user node session key parameter according to the generated element of algebra curve. The user node generates user node session key according to the user node session key parameter; the server and the user node authenticate each other according to respective generated session key. The system includes the server and the user node. A server and a user node. The user node generates the logging information parameter according to the user node password and the generated element of the algebra curve, and the server generates the user session key parameter only according to the generated element of the algebra curve. So that safe and efficient bidirectional authentication based on the password can be realized. In term of realization, the solution is more simple and feasible compared with existed authentication solution, and it is suitable for user node authentication under gridding calculating platform.
