针对传统的图像加密算法在效率和安全性上的不足,提出一种图像加密并行算法Square,该算法由Square像素排列和改进的混合操作等运算构成。满足图像加密并行算法的4个要求,加密速度和安全特性超过了MASK图像加密并行算法,具有安全、快速和简洁等优点,可在实际的并行计算平台上使用。
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.
