A Robust Low Power Chaos-Based Truly Random Number Generator

Abstract
This paper presents a low power,truly random number generator (TRNG) based on a simple chaotic map of the Bernoulli shift,which is extended to remain robustness in implementation.The map is realized by switched-current techniques that can fully integrate it in a cryptosystem on a chip.A pipelined architecture post-processed by a simple XOR circuit is used to improve the entropy.The TRNG is fabricated in an HJTC 0.18μm CMOS mixed signal process,and the statistical properties are investigated by measurement results.The power consumption is only 1.42mW and the truly random output bit rate is 10Mbit/s.-
