Аннотація | This paper presents the development and investigations of the binary key stream generators statistical characteristics. Developed generators based on the elementary rules of cells interaction: simple, modified and combined classical rules. We believe that elementary rules "30", "86", "135", "149" are most promising from statistical point of view. Modifications were consist of combining of array bits before outputting and combining various elementary rules of automaton cells interaction. It was developed a new simple interaction rule, based on the logical operation XOR. The investigation of statistical properties was performed using NIST STS v1.8. All designed generators showed good statistical characteristics, which indicates their satisfactory cryptoresistance. In addition we've investigated the developed generators linear complexity using Berlekamp-Massey algorithm. Obtained results shows the high values of linear complexity (about half of the cellular automaton length), which is typical for such s |
