摘要 在含脱线可信第三方的不可否认协议中,TTP的参与暴露出协议双方可能有一方不诚实,产生不好的社会影响。文章基于一类新型的CEMBS设计出一个含透明可信第三方的不可否认协议,仅从证据看不出TTP是否参与过此次协议,并且协议具有保密性、有效性、公平性与不可否认性。 In the previous non-repudiation protocols with off-line TTPS,the intervention of the TTP may be duo to a cheating party and exert a bad publicity.This paper designs an non-repudiation protocol with a transparent off-line TTP on the basis of a new CEMBS.This means that at the end of the protocol,by only looking at the produced evidences,it is impossible to decide whether the TTP did intervene in the protocol execution or not.And the protocol has security,effectiveness,fairness and non-repudiation.
