— Random number generators represent one of basic cryptographic primitives used to compose cryptographic protocols. While Field Programmable Gate Arrays (FPGAs) are well suited for implementing algorithmic random number generators (pseudo-random number generators), generating fast and secured true random bitstreams inside FPGAs is an open problem. Most of(More)
—The paper deals with true random number generators employing oscillator rings and namely with the one proposed by Sunar et al. in 2007 and enhanced by Wold and Tan in 2009. Our mathematical analysis shows that both architectures behave identically when composed of the same number of rings and ideal logic components. However, the reduction of the number of(More)
