Thermal noise random number generator based on SHA-2 (512)

Abstract

Couple to the rapid development of cryptography, the strength of security protocols and encryption algorithms consumingly relies on the quality of random number. This paper presents a new and security random number generator architecture. The philosophy architecture is based on SHA-2 (512) hash function whose security strength ensures the unpredictability of the produced random numbers. Furthermore, an FPGA-based implementation of architecture is described. The proposed architecture is a flexible solution in many applications taking into account the performance, power consumption, flexibility, cost and area.
