Abstract:

Aiming at the shortcomings of traditional image encryption algorithm in efficiency and security, a new image encryption algorithm named square is proposed, which is composed of square permutation and revised mixing operations. The new algorithm satisfies all requirements for parallel image encryption. It is faster and securer than MASK algorithm and can run on practical parallel computing platform.
