Abstract

Abstract:

A new sign-cryption scheme with the feature of forward secrecy was presented in order to realize the authentication during the procedure of mobile communication. The analysis result of scheme shows that superiority in efficiency and secrecy of elliptic curve system has been maintained exactly, the new scheme is sufficient to the forward secrecy unlike those sign-cryption schemes in existence. If two parties in the communication crash with each other, the third one will solve the problem, it means the arbiter.

Key words: elliptic curve cryptosystem, sign-cryption, forward secrecy, arbiter
