NAND Flash Memory Devices Security Enhancement Based on Physical Unclonable Functions

Abstract

True random number generators (TRNGs) are used in a wide range of applications (e.g., cryptography, statistical sampling, simulation, computer games, etc.). TRNG can be implemented as a part of NAND flash memory device controller and used to support Trusted Computing Group (TCG) standard. The main advantage of TRNGs comparing to pseudorandom number generators (PRNG) is the uniqueness and unpredictability of their produced output values. TRNG is a device or a part of a device that generates random numbers based on some intrinsic physical process. One of the possible ways of extracting random data from electronic devices is to implement physical unclonable functions (PUFs).
