Abstract

Wireless communication products are growing ever more popular and have become a necessity for many people. However, one difficulty frequently arising in communications and computing is the generation of random numbers for encryption keys and authentication [ 1 J. This paper introduces an ele- gant, yet simple hardware random number generator (RNG) that yields statistically unbiased random numbers [2][6][8]. By utilizing existing structures commonly encountered in wireless data devices, the approach is extremely low in complexity and does not require additional special purpose analog struc- tures, completely symmetric digital structures [8], or additional memory or digital logic [7].
