Matrix based cryptographic procedure for efficient image encryption
2011 IEEE Recent Advances in Intelligent Computational Systems, 2011•ieeexplore.ieee.org
In this paper we propose a cryptographic transformation based on matrix manipulations for
image encryption. Substitution and diffusion operations, based on the matrix, facilitate fast
conversion of plaintext and images into ciphertext and cipher images. The paper describes
the encryption algorithm, discusses the simulation results and compares with results
obtained from Advanced Encryption Standard (AES). It is shown that the proposed algorithm
is capable of encrypting images eight times faster than AES.
