Multi-party Non-repudiation Protocol with Different Message Ezchanged

摘要：

Based on the hardness assumption of discrete logarithm problem and a group oriented encryption scheme, a new multi-party non-repudiation protocol is presented. The features of this protocol are the following: In the B2C or B2B E-commerce application,it is necessary for an organisations/ people to deal with all kinds of requests,business documents, agreements, payments, contracts, acknowledgments as a batch.The protocol allows such organisations/people to send different messages to multiple different recipients, eliminates the previous restriction on the exchange of the same message. The protocol also utilizes an off-line third trusted party (TTP for short) and has higher efficiency than those protocols with an on-line TTP.
