In this paper, an encryption algorithm for images using a secret key of 128-bits is proposed. To improve the security of the encrypted image, a unique timestamp is used while encryption. Initially, the image is divided into multiple blocks and each block is encrypted separately. And final image is obtained by combining these blocks of data. Simulation results have been given to validate the security features and effectiveness of the proposed system.
