Abstract: In this paper, we present a new chaotic block cipher in which a logistic map, Henon map, and secret key are used. In the proposed chaotic cipher, the confusion and diffusion are achieved respectively with the help of chain block ciphering and secret key dependent permutation boxes. Due to the excellent confusion and diffusion properties, the proposed chaotic cipher is extremely robust. The results of the statistical analysis show that the chaotic cipher posses all features needed for a secure system and useable for the security of communication system.

Keywords: chaotic block ciphers; permutation boxes; secret key; cryptography; chaotic maps; logistic map; Henon map; chain block ciphering; secure communications; security.
