Abstract

. Software solution for cryptographic hash functions based on sponge construction with inner state implemented as two-dimensional cellular automata (CA) has been developed. To perform pseudorandom permutation in round transformation function several combinations of CA rules 30, 54, 86, 150 and 158 have been proposed. The developed hashing mechanism provides effective parallel processing, ensures good statistical and scattering properties, enables one to obtain hash of a varying length and reveals strong avalanche effect.
基于二维元胞自动机的密码哈希函数的开发与研究
. 提出了一种基于海绵结构的加密哈希函数的软件解决方案,其内部状态实现为二维元胞自动机(CA)。为了对圆变换函数进行伪随机置换,提出了几种CA规则30、54、86、150和158的组合。所开发的哈希机制提供了有效的并行处理,保证了良好的统计和散射特性,使人们能够获得不同长度的哈希,并显示出强大的雪崩效应。
