Security analysis of a multiple pseudorandom-bit generator based on a spatiotemporal chaotic map 下载免费PDF全文
<正>In this paper we analyse the security of a multiple pseudorandom-bit generator based on the coupled map lattice and suggest an improved model.Utilizing the error function attack,the multiple pseudorandom-bit generators which can be realized by the three digitization methods are analysed and the effective key spaces are estimated.We suggest an improved multiple pseudorandom-bit generator with 128-bit secret key,and analyse the key sensitivity and statistical properties of the system. 相似文献
