Raw QPP-RNG randomness via system jitter across platforms: a NIST SP 800-90B evaluation

Abstract High-quality randomness is fundamental to the security of modern cryptographic systems. We present QPP-RNG, a true random number generator (TRNG) that harvests entropy from diverse system-level jitters–including CPU pipeline timing divergences, DRAM refresh cycle perturbations, cache miss-d...
