Chaos is the inherent characteristics and common phenomenon of dynamical systems. Chaotic system is characterized by sensitive dependence on initial conditions and control parameters, pseudo-randomness and unpredictability, which make chaos can be applied to the design of cryptosystem. Recently, a lot of chaos-based image encryption algorithms are proposed. Three of them are analyzed in this

Due to the characteristics of chaos systems such as good pseudorandom, ergodic,high sensibility to the initial values, and long inscrutability, chaos has great potentialapplication in practical engineering. For example, the encryption algorithms based onchaos are presented to protect digital information against illegal copying and distributionover the Internet; and the weak signal can be tested by
