Wang et al. proposed a double verifiably encrypted signature (DVES) scheme which can be used to design the contract signing protocol systems. In this paper, we propose an efficient contract signing protocol based on the DVES scheme. A semi-trusted third party is involved in our protocol to ensure firness. Moreover, the new contract signing protocol satisfies the desirable properties: unforgeability, opacity, extractability, timeliness, effectiveness and fairness.
