%X Based on the study of some existing chaotic encryption algorithms,a new block cipher was proposed.The proposed cipher encrypts 128-bit plaintext to 128-bit ciphertext blocks.It consists of eight computationally identical rounds transformation.All roundkeys are derived from K and a 128-bit pseudorandom binary sequence generated from a chaotic map.Analysis shows that the proposed block cipher does not suffer from the flaws of pure chaotic cryptosystems and possesses high security.
