Abstract

Abstract:

Electronic commerce is a main trend in Internet applications ,which should be based on fair exchange. A new fair exchange protocol with semi-trusted third party is proposed on the basis of a new convertible authenticated encryption scheme. Compared to the optimistic fair exchange protocols, the new protocol has a simpler structure and a lower communication overhead and the properties of privacy, faireness, non-repudiation and timeliness are satisfied.

Key words: fair-exchange, Semi-Trusted Third Party(STTP), convertible authenticated encryption
