摘　　要：为了保护在网络中所传输邮件的安全性,基于一维分段线性混沌模型,设计了安全高速且易于实现的电子邮件混沌加密软件,给出了对文本文件加密和解密的算法、具体实现和效果,最后主要从统计特性、密文敏感性以及抗攻击性等三方面对安全性进行了分析,证明了系统的可靠性。For protecting the security of email transmission on the Internet,this paper proposes a fast and easy-to-realize email encryption algorithm based on the one dimension piecewise linear chaotic model.A kind of software for encrypting and decrypting text files has also been implemented based on the proposed algorithm.Finally,the security is analyzed from three sides which include statistical properties,sensitivity to cipher-text and resistance to known attacks and so on mainly.Simulation results indicate the reliability of the system.
