A novel oscillator-based TRNG for smart IC card

Xiaoyan Jia, Liji Wu, Beibei Wang, Xiangmin Zhang

Open publisher page 4 citations

Abstract

True random number generator (TRNG) is a vital part of many cryptographic protocols. This paper introduces a ring oscillator based TRNG for smart IC card. To generate high quality random bits, inter-stage feedback ring is introduced to control the frequency of the high speed ring oscillator to accumulate the phase noise. To detect electromagnetic attack [1], a detection circuit is designed. This TRNG is implemented in SMIC 0.13 μm EEPROM CMOS process. Post-simulation results show that the random bit stream can pass statistical test for randomness. The novel TRNG circuit has been taped out in May.
