low diffuser meaning in Chinese

低扩散系数杂质

Abstract aiming at the defects of diffusion function with lower diffusing speed and needing multiple round iteration to resist differential attack in the image encryption algorithm based on chaotic block cipher , a new chaotic image encryption algorithm based on output ? cryptograph mixed feedback was proposed
摘要针对现有基于混沌分组密码的图像加密算法中，扩散函数扩散速度慢、需要多轮迭代才能抵抗差分攻击的缺点，提出了一种新的基于密文和输出混合反馈的混沌图像加密算法。
