An Analysis of Flipped Cryptographic Block Cipher Mechanism for Image

This paper proposes and examines a different encryption algorithm for Cipher Block Chaining mode (CBC) which is designed for improving the security of a cryptographic algorithm and more resisting cryptanalysis. The size of both block and key are chosen depending upon the size of the image. The fixed key size will lead to some fuzzy attack, Hence the number of bits in key size is decided by the size of the plaintext image. The encryption operation is mainly done by flipping. The amount of flipping depends on the size of the image. The image is divided into four parts, and each part undergone different flipping. This approach makes the implementation cost less than the current Data Encryption Standard (DES) and Advanced Encryption Standard (AES). The security analysis process also proves that the proposed algorithm can resist the statistical and differential attacks. Citation: Sivasankari Narasimhan, Santhosh GJ, Venkata Subramanian G.
