A Bulk Email Oriented Multi-party Non-repudiation Exchange Protocol

摘要

Much research has been done in the area of non-repudiation protocol. There are lots of research results on multi-party non-repudiation protocols. However, only a few of them present examples of applying the protocol to the Email-system. In this paper, a Bulk Email Oriented Fair Multi-party Non-repudiation Protocol is proposed. With the use of the online TTP to collect evidence from the sender and the receivers, the non-repudiation property among the sender and the receivers is provided, as well as the fairness among the receivers. The correctness of this protocol is proved using the formal method of SVO logic.
