Abstract: Security services becomes crucial to many applications such as e-commerce payment protocols. Online contract signing protocol is fair as it allows two users to exchange their digital signatures in a secure manner such that both the users remain loyal to the transaction. The trusted third party is involved only in the situations where one party is cheating other or the communication channel is interrupted. Also, if the protocol is executed unsuccessfully, none of the parties can show the validity of intermediate results to others. As more business is conducted over the internet, the fair-exchange problem is gaining greater importance. In this paper, we make a comparative study of different online contract signing protocols and give the best efficiency results.
