A Review on Chaotic Map Based Cryptography
This paper presents a review of Image cryptography techniques based on chaotic maps. The chaotic cryptography is gaining more attention than others because of its lower mathematical complexity & better Security. It also avoids the data spreading hence reduces the transmission cost & delay. The digital image cryptography which is based on chaotic systems utilizes the discrete non-linear system dynamics generally called chaotic maps. Depending upon the type of system many types of chaotic maps are available. By combining them a large number of cryptographic techniques could be designed in this paper we are presenting a review of some of those techniques.
