Type: conference-paper
Abstract: This paper presents a new chaos-based True Random Number Generator (TRNG) with decreased voltage supply sensitivity. Contrary to the traditionally used sources of randomness it uses well-defined deterministic switched-capacitor circuit that exhibits chaos. The whole design is embedded into commercially available mixed-signal PSoC reconfigurable device without any external components. Proposed design is optimized for reduction of influence of supply voltage to the quality of generated random bit stream. The influence of circuit non-idealities is significantly reduced by the proposed XOR corrector and optimized circuit topology. The ultimate output bit rate of proposed TRNG is 60 kbit/s and quality of generated bit-streams is confirmed by passing standard FIPS and correlation statistical tests performed in the full range of PSoC device supply voltages.
