Abstract:
Chaos systems are characterized by its critical sensitivity to initial conditions and parameters, pseudo-randomness, and determinability. In this paper a software platform is brought forward, which can be used to generate and evaluate chaotic binary sequences. It utilizes three typical kinds of chaotic dynamics model to generate encryption sequences. Massive experim ents on randomness, sensitivity and repeatability verify that chaotic sequence has higher performance in encryption. Besides, it has the capability to encrypt and decrypt many kinds of objects. The experimental results have been given on bitmap image en cryption as an example.
