Design and Implementation of Image Encryption Algorithm by using Block Based Symmetric Transformation Algorithm

7 Abstract: The primary goal of this paper is security management. This will provide authentication of users, and integrity, accuracy and safety of images which is traveling over internet. Moreover, an image-based data requires more effort during encryption and decryption. The Proposed Architecture for encryption and decryption of an image using suitable userdefined key is developed with the same objective. In this paper, we introduce a new permutation technique based on the combination of image permutation and a new developed encryption algorithm called “Hyper Image Encryption Algorithm (HIEA)”. From the selected image we will binary value blocks, which will be rearrange into a permuted image using a permutation process, and then the generated image will be encrypted using the “Hyper Image Encryption Algorithm (HIEA)” algorithm.
