A Random Number Generator Based on Particle Dynamical Evolutionary Algorithm

High quality random number is widely used in the cryptography, key management, cryptographic protocol, digital signature, and authentication. In this paper, we propose a new random number generating method which is based on the theories of Particle Dynamics Evolutionary Algorithm (PDEA) and Evolvable Hardware (EHW). We devise a Random Number Generator (RNG) of two-layer PDEA. The major features of this platform are: two-layer encoding of circuit structure, off-line evolving with software emulation and the evolving of PDEA designing. With this platform, we implemented the auto-designing of some software hardware systems, the numerical experiments also show that the random number generated in this paper with high randomicity, more chaos and long periodicity.
