Abstract

In this paper, the authors propose a new chaotic block cryptosystem based on multiple one-dimensional chaotic maps. In the proposed cryptosystem, the authors establish map-to-task relations between the multiple chaotic maps and the tasks, which must be performed in the encryption rounds. The encryption process is based on these map-to-task relations. The authors enhance the security of the cryptosystem by changing the map-to-task relations constantly and applying plaintext and ciphertext feedback in the encryption process. Experiments and theoretic analysis show that the proposed cryptosystem possesses high performance and security.
