Book excerpt: Chaos cryptography is an inter discipline that combines chaotic theory and cryptography, which includes chaotic secure communication system, chaotic symmetric cipher, chaotic public key cipher and chaotic hash function [1]. In this academic monograph, the main object of our discussion is symmetric chaotic cryptography. The block diagram of symmetrical encryption and communication transmission is shown as Figure 1 [2]. The encryption process is ( , ) EK =CP, in which P means plaintext while K means secret key and () E ? represents encryption function. Alice sends the ciphertext which has been encrypted to Bob, the receiving end. Bob makes use of the same secret key which is sent by a secure channel to decrypt and recover the original plaintext ( , ) DK =PC, in which ()D ? is the decryption function. For an attacker Oscar, the ciphertext C is available but the secret key for the secure channel transmission is not known.
