| Abstract: | Analyzing the principle of chaotic sequence encryption, the production of keys stream, and the space of keys. An encryption mode based on Logistic chaotic sequence was proposed. Through analyzing the algorithm, it has anti broken strength for searching for keys and chosen plaintexts. By using the VS.Net development tools, an encryption software called Smartdog was implemented. The software suits to encrypt any data files. Finally, the features of chaos encryption are compared with some general encryption algorithms, such as DES and RSA. |
