Testing of PLL-based True Random Number Generator in Changing Working Conditions

Testing of PLL-based True Random Number Generator in Changing Working Conditions

Security of cryptographic systems depends significantly on security of secret keys. Unpredictability of the keys is achieved by their generation by True Random Number Generators (TRNGs). In the paper we analyze behavior of the Phase-Locked Loop (PLL) based TRNG in changing working environment. The f...
