Abstract [en]

True random number generators (TRNGs) are important hardware primitives required for many applications including cryptography, conmumication, and statistical simulation. This paper presents a non-linear feedback ring oscillator (NI, FRO) based entropy source for implementing high performance TRNGs on FPGAs. The proposed NLFRO structures harvest randomness from noise and unpredictable variation in delay cells and bi-stable elements which are further amplified by non-linear feedback loops. The outputs of NLFROs show chaotic behavior, making them suitable for implementing high entropy, high speed and attack resistance TRNGs. Three NLFRO-TRNGs are implemented and tested on an Altera 60nm FPGA device. Raw entropy and statistical properties of the NLFRO-TRNGs are examined by the NIST 800-22 entropy estimation and NIST 800-90B statistical test suits. Compared to the prior art, experimental NLFRO-TRNGs show higher entropy and lower resource usage while consuming sub-milliwatt at 200 Mbps.
