基于复合符号混沌的伪随机数生成器及加密技术
A new pseudo-random number generator and application to digital secure communication scheme based on compound symbolic chaos
摘要
Abstract
A new concept of compound symbolic chaotic series is proposed.According to the kneading pair series in symbolic dynamics,by compounding a pseudo-random series with sub-series on condition of kneading rules we obtain a new symbolic chaotic series which is then transformed into a pseudo-random binary number （PRN） series.The length of the new PRN series elongates at a speed of geometric procession with iteration number.Theoretical and experimental analyses both prove that the above algorithm provides an effective PRN generator.To apply the algorithm to digital secure communication,a new cellular automata is established.With the automata,the data expansion is avoided,the encryption is finished quickly,the obvious avalanche effect can be produced,and thus the security is improved.关键词
