Contemporary Encryption Technique for Images using CLEFIA

Abstract

In contemporary planet we are distributing lot of particulars through electronic media. In innumerable fields this information should be protected. Few examples in which the particular should be protected are military, industries, scientific research etc. In proposed effort we encompass three parts. In first part, we are using CLEFIA to encrypt images, and in second part we are using CLEFIA to decrypt images and in third part we are using error rectification and recognition technique using Low Density Parity Check convention. CLEFIA is the block cipher algorithm. The block size of CLEFIA is 16 bytes and the key size is 16 bytes, 24 bytes and 32 bytes. After Encryption of images using CLEFIA the images will be sent to the recipient in the form of binary bits. While transmitting these binary bits through communication channel, particulars may get distressed due to noise and to tenacity; Low Density Parity Check Convention is used in the receiver side.
