Improved Image Encryption Algorithm using Chaotic Map
Rohit Joshi, Sumit Joshi · International Journal of Computer Applications · 2011
This paper proposes an improved image encryption scheme over existing scheme. The distinct feature of improved encryption scheme is that it encrypts the image using chaotic maps only without further confusing this encrypted image as illustrated in existing scheme. Further, the advantages over existing scheme are 1) the proposed algorithm is completely retrievable in contrast to the existing algorithm 2) the experimental results of proposed algorithm are better than existing algorithm which governs added security level and 3) lesser computational complexity which governs improved speed performance.
