This paper develops an efficient pseudo-random number generator for validation of digital communication channels and secure disc. Drives. Simulation results validates the effectiveness of the random number generator.

In this paper, we give two explicit constructions of extractors, both of which work for a source of any min-entropy on strings of length n. The rst extracts any constant fraction of the min-entropy using O(log n) additional random bits. The second extracts all the min-entropy using O(log n) additional random bits. Both constructions use fewer truly random bits than any previous construction whi...
