Improvement and Analysis of a Pseudo Random Bit Generator by Means of Cellular Automata
In this paper, we implement a revised pseudo random bit generator based on a rule-90 cellular automaton. For this purpose, we introduce a sequence matrix HN with the aim of calculating the pseudo random sequences of N bits employing the algorithm related to the automaton backward evolution. In addition, a multifractal structure of the matrix HN is revealed and quantified according to the multif...
متن کاملAnalysis of Pseudo Random Sequence Generated by Cellular Automata
The security of cellular automata for stream cipher applications is investigated. A cryptanalytic algorithm is developed for a known plaintext attack where the plaintext is assumed to be known up to the unicity distance. The algorithm is shown to be successful on small computers for key sizes up to N between 300 and 500 bits. For a cellular automaton to be secure against more powerful adversari...
