Abstract: 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.
