In ACISP 04, the authors of [5] suggested a fair exchange protocol for electronic contract signing between two parts. The protocol is an improvement of a previous one [10] and solves the vulnerabilities of that protocol. In [5] one of the signers can contact a trusted third party to resolve the exchange if he can?t conclude it in the usual way. However, the other signer cannot contact the trusted third party, and for this reason, this signer can?t know the final state of the exchange until, if it is the case, the trusted third party contact him or her. In this paper we have improved the protocol so that both signers can contact the TTP and solve the exchange whenever they want. We propose an asynchronous and fair protocol that improves the protocol presented in [5] maintaining the efficiency of the original protocol.
