Performance Analysis of Image Encryption Using Block Based Technique

Rupali Srivastava, O. P. Singh

In digital communication and multimedia application, security is must for communication and storage of images. Image Encryption is one of the best methods to ensure high security images which are generally used in medical science, military applications. In this paper, an efficient technique is proposed with the help of cipher block chaining (CBC) operation, which is used for image encryption. We test our proposed technique using MATLAB R2013a, it can achieve various image quality parameters such as the mean square error(MSE), peak signal to noise ratio (PSNR) and the overall time taken by the algorithm to perform the process is also computed.
