A Double-Scroll Based True Random Number Generator with Power and Throughput Adjustable

摘要：

A new double-scroll chaotic oscillator circuit is proposed to design a true random number generator (TRNG) in CMOS process. The proposed oscillator is base on differential amplifiers by only MOS trans.istors and especially suitable to be integrated in standard logic process. The power of the oscillator is adjustable from 369μW to 2. 7μW with different speed levels, proving low power operation ability and wide adjusting range. A low cost TRNG is realized and the quality of the output sequences is evaluated when the whole circuit consumes 53μW. The sequences pass the NIST FIPSI40-1 standard randomness test at 1MHz clock frequency,showing better throughput-power efficiency compared to other papers.
