基于J2ME和混沌加密的安全移动商务方案

A Secure Mobile Commerce Scheme Based on J2ME and Chaos Encryption

本文提出了一个端到端的安全移动商务方案,它是基于J2ME并采用密钥动态更新的快速混沌加密技术而实现的。针对混沌序列的特点,本文提出密钥生成与加密过程分离;对软件实现的有限字长效应,采用了两次反馈混沌加密。一个实例证实了本文的方案。

An end-to-end secure scheme for mobile commerce is proposed in this paper. It is designed and realized based on J2ME and fast chaos encryption with dynamical key. According to the character of chaotic sequence, the key is separated from the process of encryption. Because the effect of the limited word-length always exists, the user data is encrypted two times by feedback.An example is demonstrated.
