混沌是非线性确定系统的现象,在经过多次迭代后会表现出类似随机的特性,具有优良的密码学等特性,可以较好的应用于密码算法中,计算机硬件的设计和序列的数值化都会降低混沌序列的随机性,工作重点是选取适当的编码对混沌序列数值化,尽可能的保留混沌序列的数值化后的随机性,给加密算法提供一个较优良的密码序列。 Chaos is a non-linear system of determining the phenomenon, after repeated iterations will show similar random characteristics, with excellent cryptography and other characteristics, can be better applied to the cryptographic algorithm, the design of computer hardware and the numerical sequence of the city Reduce the randomness of chaotic sequence, the key point of work is to select the appropriate code to digitize the chaotic sequence, keep the randomness of the chaotic sequence as much as possible, and provide a better cryptographic sequence to the encryption algorithm.
