Encryption Function

A General Feistal Structure based color image encryption and authentication algorithm is designed in this paper. The plain image is first permuted, then divided into groups of size pixels and encrypted by block encryption algorithm; finally the cipher image is obtained by performing inverse permutation on the image. In which, block encryption function is the kernel part of the encryption algorithm, and is designed with general feistel structure. To provide integrality authentication function, the last cipher block is the cipher of the sum of all plain blocks. It’s from experiments and analysis that the algorithm is secure and valid.
