Abstract

Abstract: This paper presents an approach to realize finite precision chaotic systems via perturbation of chaotic-sequences.After being perturbed，chaotic system can generate chaotic binary sequences with uniform distribution and statistic properties invulnerable to cryptographic analysis.The simulation result shows that the perturbing scheme is effective. Encryption matrixes and replacement matrixes are being generated by using the chaotic mapping via parameter perturbation，and then the gray-scale image is encrypted.Experimental simulation shows that the encryption algorithm has a good effect of encryption.

Key words: parameter perturbation, tent map, finite precision effect, digital chaotic systems, image encryption
