Abstract :
Securing digital image during transmission is very much important in the current era. For this purpose, cryptographic techniques as well as chaotic maps can be applicable. In this paper, we have given a detailed study of the image encryption using different 2D chaotic maps such as Arnold 2D cat map, Baker map, Henon map, Cross chaos map and 2D logistic map. The security analysis of these techniques has been done by the help of NPCR (Number of Pixels Change Rate) and UACI (Unified Average Changing Intensity) values. The experimental results of NPCR and UACI show the effectiveness of the encryption processes of different techniques.
