摘要
由于密码分析研究的进展及DES自身的弱点,原64比特的DES将不能作为数据加密的标准算法而长期存在。在原来工作的基础上,本文提出了256比特的分组密码方案。密码算法由基于混沌映射的数字滤波器构造。
The DES algorithm(64 bits) will not last for a long period as the standard data encryption algorithm because of its weakness and the development of cryptanalysis. On the basis of previous work, an improved block cipher scheme of 256 bits is presented in this paper. The algorithm comes from the digital filter using a chaotic map. By the simulated test of computer, it turns out that this algorithm has excellent security. And comparing with traditional block encryption to control the bit - length and the iteration times.
