Pseudorandom number generator - The Self Programmable Cellular Automata

Abstract

This paper deals with the problem of generating high quality random number sequences for cryptography. A new class of CA, the Self Programmable Cellular Automata (SPCA) is proposed. Experimental results showed the sequences generated performed well in the ENT and DIEHARD test suites; comparable to the results obtained by other researchers. Furthermore, the SPCA has implementation space savings over other similar variants of CA. The SPCA uses only Boolean operations hence it is ideally suitable for VLSI hardware implementation.
