摘要: In this paper, a new, patent pending, architecture for jitter-based random bit source which is cost-effective and suitable applications in cryptography, presented. The designed to be robust against parameter variations attacks aimed force its output. It also features an auto-test allows detect faults estimate the entropy. proposed design enhancement of oscillator-based where compensation loop added maximize statistical quality output sequence, especially presence low-jittered oscillators. As consequence, fully-digital implementation, without any amplified noise source, can adopted generator. From analysis known techniques number generation, derived implementation details are reported.
