Dual‐metastability FPGA‐based true random number generator

A novel concept of a true random number generator (TNRG) based on two metastable flip‐flops in a FPGA circuit is introduced. Most of metastable based TRNG solutions are based on the assumption of a D‐latch (flip‐flop) state's uncertainty which is the source of randomness. In the proposed approach…
