With the progress in data exchange by electronic system, the need of information security has become a necessity. Due to growth of multimedia applications, security becomes an important issue of communication and storage of images Encryption and Decryption is used to securely transmit data in open networks. Each type of data has its own features; therefore different techniques should be used to protect confidential image data from unauthorized access.The principle goal of designing any encryption and decryption algorithm is to hide the original message and send the non readable text message to the receiver so that secret message communication can take place over the web. The strength of an algorithm depends on the difficulty of cracking the original message. In kind of algorithm .a combination of four S –boxes lookups, multiplications as well as fixed and data dependant rotations will be used. In this paper we would be obtaining our results by simulating the image processing by Encryption and Decryption part in MATLAB.
