Abstract:
Fair exchange protocol is the basis of secure electronic commerce where the RSA cryptosystem gains comprehensive applications. This paper presents a new efficient verifiable encrypted RSA signature scheme, on which a simple and practical optimistic fair exchange protocol is been devised. Analysis and comparisons show that this protocol is secure and fast.
Key words:
