Abstract

In this paper a novel TRNG concept is proposed which is a vital part of cryptographic systems. The proposed TRNG involves phase variability of a pair of ring oscillators (ROs) to force the multiple metastable events in a flip-flop (FF). In the solution, the ROs are periodically activated to ensure the violation of the FF timing and resultant state randomness, while the TRNG circuit adapts the structure of ROs to obtain the maximum entropy and circuit security. The TRNG can be implemented in inexpensive re-programmable devices (CPLDs or FPGAs) without the use of Digital Clock Managers (DCMs). Preliminary test results proved the circuit's immunity to the intentional frequency injection attacks.
