A Multi-party Optimistic Non-repudiation Protocol

In this paper we consider the optimistic approach of the non-repudiation protocols. We study a non-repudiation protocol with off-line trusted third party and we keep on with the definition of the multi-party non-repudiation, compare it to multi-party fair exchange and show some fundamental differences between these two problems. Finally, we generalize our protocol and propose a multi-party non-repudiation protocol with off-line trusted third party.
