Abstract

protecting the privacy of message receivers is an important issue in pay services of e-commerce and the distribution of digital contents on the Internet. This paper proposes an efficient privacy of message encryption algorithm called PMEA for pay services of e-commerce. In PMEA, each of the receivers only needs to perform constant times of pairing computation to decrypt the received message. PMEA adopts bilinear pairings on elliptic curves to protect the privacy of message receivers, to ensure that an attacker or any other message receiver can not derive the identity of a message receiver such that the privacy of every receiver can be guaranteed. Detailed theoretical analysis proves that PMEA is secure and anonymous for message receivers. Keywordsprivacy message; encryption algorithm; anonymous receivers; E-commerce
电子商务中匿名接收者消息加密算法的高效保密性
信息接收者的隐私保护是电子商务支付服务和互联网数字内容分发中的一个重要问题。针对电子商务支付服务,提出了一种高效的消息隐私加密算法PMEA。在PMEA中,每个接收方只需要执行一定次数的配对计算来解密接收到的消息。PMEA采用椭圆曲线上的双线性对来保护消息接收者的隐私,保证攻击者或任何其他消息接收者无法推导出消息接收者的身份,从而保证每个消息接收者的隐私。详细的理论分析证明了PMEA对消息接收方具有安全性和匿名性。Keywordsprivacy消息;加密算法;匿名接收器;电子商务
