摘要

公平是电子商务协议和应用的基本要求之一。证明了CEMBS是构建公平交换协议的重要密码构建原语。本文分析了现有cembs实现方法的不足。提出了一种新的基于RSA签名的cembs构造方法，该方法简单、高效、安全。然后，使用新构建的CEMBS构建公平交换协议。本文设计的方案是第一个基于RSA签名的高效CEMBS方案。

A new CEMBS based on RSA signatures and its application in constructing fair exchange protocol

Fairness is one of the basic requirements of e-commerce protocols and applications. CEMBS is proved to be an important cryptographic building primitive in constructing fair exchange protocols. In this paper the drawbacks of existing CEMBS-implementing methods are analyzed. A new CEMBS-constructing method based on RSA signature is proposed, which is proved to be simple, efficient and secure. Afterwards, a fair exchange protocol is built using the newly constructed CEMBS. And the devised scheme in this paper is the first efficient CEMBS based on RSA signatures.
