Abstract

Recently, Zhou et al. proposed a verifiably encrypted RSA (VE-RSA) signature scheme, which was used to convince that an encrypted message is a certain party´s signature on a message while without revealing the signature. In this paper, we propose a new optimistic fair exchange protocol based on the verifiably encrypted RSA signature scheme. In our scheme, both parties can contact the TTP and settle the argument before the deadline. Moreover, our new scheme achieves fairness and timeliness.
