摘要
不可否认性和公平性是电子商务交换协议中的两个重要性质 .本文以带盲密文的可验证加密方案为基础 ,提出了一种新的带有脱线半可信第三方公平的非否认协议 。
Non repudiation and fairness turn out to be two important security properties of electronic commerce protocols.In this paper,based on a verifiable encryption with blind decryption,we present a new fair non repudiation protocol with off line semi trusted third party,so either transaction party can unilaterally bring a transaction to completion without losing fairness.This is the first non repudiation protocol with off line semi trusted third party.
