摘要
伪随机数发生器在密码学领域尤其是流密码具有举足轻重的地位,通常是通过物理设备或算法来产生.变值逻辑体系提供了一种伪随机数序列的产生方法,新型变值逻辑伪随机数发生器的设计充分利用变值逻辑理论中两个特有运算,并在基于变值逻辑的框架下,加入了提高生成序列随机性能的控制机制.该发生器在变值逻辑理论框架下产生的变值逻辑表拥有很长的周期和巨大的控制参数空间.最终将生成的0,1序列以16bit为分段转化成散点图进行对比分析并显示出良好的随机特性.
The pseudo-random number generator,especially in the field of cryptography stream cipher,has a pivotal position,usually producting by a physical device or algorithm to produce.Variant logic system provides a pseudo-random number sequence generating method.The new variable-valued logic pseudo-random number generator designed to take advantage of changes in value in two specific operational logic theory and based on variable-valued logic framework,adding randomly generated sequence to improve the performance of control mechanisms.The variant logic generating under the chareyrng theoretical frarnevwrk has a very long cycle and great control parometer spate.0,1 eventually generated sequence is segmented into 16bit comparative analysis plot and shows excellent random properties.
