Abstract

Electronic exchange is widely used in e-commerce systems. This paper mainly discusses abuse-freeness in general item exchange protocol for two parties. Based on convertible signature scheme and adapted designated verifier proof, an efficient item exchange protocol is proposed to satisfy many interesting requirements including fairness, timeliness and strong abuse-freeness.
