Realization of Image Encryption Scheme Based on Chaotic Binary Sequence

Due to extensive research of non-linear science theory (the chaos) in the image encryption, we find especially that the properties of chaos make itself particularly suitable for image encryption. On the basis of many excellent features of chaotic sequence, combining application of chaotic theory in cryptography, the paper puts forward image encryption based on chaotic binary sequence. On Logistic digital chaotic system platform, the paper gives the realization mechanism of image encryption based on digital chaotic binary Logistic sequence. Meanwhile, the paper also conducts histogram analysis, key sensitivity analysis and damage resistance analysis for the encrypted image. Simulation results show that this method can better resist damage and is very sensitive for secret key.
