摘要：

连续双方拍卖（CDA）机制在电子商务领域有着广泛的应用，但该机制安全性方面的问题却没有得到相应的重视。针对这个问题，本文分析了CDA机制的相关安全性问题，即存在抵赖、冒充、伪造、难以验证等情况。在此基础上，运用RSA加密算法和数字签名技术予以解决，最后论证了本方案能够很好地解决与CDA机制的安全性问题。

关键词: 拍卖, 安全, RSA, 数字签名

Abstract:

CDA（continuous double auction）mechanism is widely used in the fields of e-commerce,but the security issues have gained little attention.In this paper,the related issues about CDA are analyzed and the problem of repudiation,impersonation,forging and hard to verify is pointed out.The RSA public key cryptosystem and digital signature are utilized to solve this problem.In the end,our scheme is proved theoretically to be effective to handle the problem.

Key words: auction, security, RSA, digital, signature
