合同签署是一项重要而频繁的商务活动.现有的合同签署方案都没有解决"强迫签署"的问题:B强迫A签署一项A不愿签署的合同.本文首次引入了"强迫签署"的概念
然后利用XTR公钥密码体制中共轭元素的性质
提出了一种无强迫的最优合同签署方案.在可信赖第三方的帮助下
A可以提供相应的证据来废除所签署的合同
从而最大程度地保证了系统的公平性.
Contract signing is a fundamental and frequent service in electronic commerce.All present contract-signing schemes cannot solve the crime of"coercive signing":
B
forces
A
to sign a contract that he would not like to sign.The concept of"coercive signing"is firstly introduced in this paper and an optimistic contract-signing scheme without coercion is proposed by using the properties of conjugate elements in XTR system.With the help of the trusted third party
A
can offer some evidence to abort the contract
so it ensures the fairness of the system furthest.
