基于混沌映射的分组密码算法
Block Cipher Algorithm Based on Chaotic Mapping
摘要
Abstract
This paper proposes a new chaotic block cipher algorithm based on a kind of extended Feistel structure which encrypts 128 bit plaintext to 128 bit cipher text. The S-box in round function is generated by logistic chaotic mapping, and puts 128 bit initial key into cubic map to generate the key of algorithm. Hardware description language of Verilog is used to design and implement the algorithm, and the encryption and decryption process are simulated by Modelsim. Experimental results show that the algorithm has high-sensitive S-box, large key space, and good performance in confusion and diffusion.关键词
