Abstract

Aiming at the shortage of medical images encryption algorithm in efficiency and security, this paper proposed a novel medical image encryption algorithm in frequent domain based on 2D sine Logistic chaotic mapping. Firstly, the proposed algorithm used the integer wavelet transform of LeGall5/3 to transform medical image from frequent domain to spatial domain. In this way, the high correlation among pixels has disappeared. Then, the proposed algorithm utilized 2D sine logistic chaotic mapping to generate the chaotic sequences. In order to improve the encryption efficiency, this algorithm chose the low frequency coefficients of three-level decomposed to encrypt with chaotic diffusion and scrambling mechanism. In the same time, this algorithm also selected the medium-high frequency coefficients of two-level decomposed to encrypt by chaotic diffusion mechanism for solving the problem of obvious outline in encrypted image. Finally, this algorithm transformed the encrypted wavelet coefficients by the inverse integer wavelet transform and obtained the encrypted image. Experimental simulation results demonstrate that the proposed algorithm is able to protect medical images with low time complexity and a high security level. Compared with the existing spatial method, it reduces the encryption time by about 0.025 times. In addition, the proposed algorithm has better image imperceptibility as well as an excellent encryption efficiency compared to the existing frequent method.
