| Popis: | 107 Due to bulk data capacity of images traditional symmetric or asymmetric encryption algorithms such as AES and RSA are seldom used to handle image encryption. A lot of works based on chaotic permutation-diffusion ciphers have been proposed to encrypt images since they generally need far less computation cost. In this work, we present a color-image cipher with chaotic permutation-diffusion scheme. This work extends a previous work that only deals with gray-level images. Furthermore, pipelined 2-round encryption is implemented. The security analysis shows that the implementation can produce encrypted images with strong resistance to various attacks. The design has been correctly verified with the NC-Verilog Simulator. |
