摘要
Abstract
A digital image encryption scheme based on double Logistic chaotic map was proposed in this thesis. The two-level Logistic chaotic map was used to create the pseudo-random sequence number in the scheme, and the number of random sequences of image diffusion and scrambling was obtained by two creation processes. The key used in the scheme is the calculation parameters of the first-order Logistic chaotic map and the initial value of the second-order Logistic chaotic map. And in the encryption and decryption process, and the encryption process includes the two steps of proliferation and scrambling. Through the encryption scheme in the. NET platform for experimental simulation, the program encryption effect is good, and it also can complete the correct completion of the image decryption processing. At last, the security and reliability of the scheme were analyzed and studied in detail in this thesis, including the key space size of the scheme, the sensitivity of the scheme to the key, the pixel correlation of the encrypted image and the information entropy, etc. Results suggest that the proposed image encryption scheme is secure and efficient, with high potential to be adopted for the secure image communication applications.关键词
