摘要: In this paper, we propose an images encryption algorithm based on the quaternion multiplication and XOR function. The proposed processes image in 32 quaternions i.e. block of 32 × 4. For each quaternion, exor ith key quaternion. is changed using multiplication. randomness evaluated by diehard package. Several other analyses are provided to evaluate performances scheme. These demonstrate that with high security level fast run speed can be competitive some recently schemes.
