Lightweight anonymous authentication and key negotiation method in multi-server environment
The invention relates to a lightweight anonymous authentication and key negotiation method in a multi-server environment and belongs to the technical field of information safety. The method is characterized by achieving the anonymous authentication and key negotiation in the multi-server environment by means of the following three steps: (1) building a system and selecting system parameters; (2) registering in a registering center RC by a server and a user; (3) carrying out authentication and key negotiation by the user and a remote server so as to provide subsequent communication session keys. The lightweight anonymous authentication and key negotiation method is applicable to remote authentication of a mobile terminal and servers with low calculation capability, memory space and communication capability; the mobile terminal can log in any server registered by RC through a user name and a password; the server only can authenticate that the user is a valid user and cannot know the specific identity of the user, so that the privacy of the user is protected; the lightweight anonymous authentication and key negotiation method is excellent in expansibility; the two-party negotiation session keys are determined by random numbers Ni1 and Ni2 selected by authenticating for each time by two parties; the independence and the forward and backward security of the session keys are ensured.
