Abstract:

Random Number Generators are important for implementation of cryptographic protocols. Physical or true random number generators (TRNGs), that use physical processes to generate random numbers, have been proposed as an alternative to Pseudorandom RNGs. Special interest lies in those that can be implemented for embedded cryptographic devices which use random sources available in hardware accelerators (PCBs, FPGA families, …)
To evaluate the security of any TRNG design, a stochastic model must be provided to estimate a lower bound on the entropy of the output bit sequence. This talk will focus on a particular oscillator design proposed in the literature and aims to provide a brief introduction to the problems related to the mathematical assessment of the performance of any given design.
