Nonlinear Dynamics in Transform Encoding-Based Authentication

Abstract

Chaos-anchored steganography and authentication have been described in this chapter. Various chaotic equations and generation of PN sequence from these chaotic equations are outlined in detail. Various tests for true randomness of binary sequence are given. Algorithm of image encryption/authentication using chaotic map in association with Arnold’s cat map and hash function is given elaborately. GA-anchored chaos for generation of optimized chaotic seed is given in detail with algorithms and results.
