High Throughput 512Mbps True Random Number Generation Using Uncertainty in Mobile Communication Bands

IEEE Access
This study presents a new approach to generating true random numbers by exploiting the random nature inherent in mobile communication networks. Taking advantage of fluctuations in total users, user activity rate, and channel fading, we receive a raw ...

An Analysis of Deterministic Chaos as an Entropy Source for Random Number Generators

Entropy, 2018
This paper presents an analytical study on the use of deterministic chaos as an entropy source for the generation of random numbers. The chaotic signal generated by a phase-locked loop (PLL) device is investigated using numerical simulations.
