New paradigms for digital generation and post-processing of random data
Jovan Dj. Golic
Abstract: A new method for digital true random number generation based on asynchronous logic circuits with feedback is
introduced. In particular, a concrete technique using the so-called Fibonacci and Galois ring oscillators is
developed and experimentally tested in FPGA technology. The generated
random binary sequences inherently have a high speed and a very high and robust entropy
rate in comparison with previous proposals for digital random number generators.
A new method for digital post-processing of random data based on
non-autonomous synchronous logic circuits with feedback is also introduced
and a concrete technique using a self-clock-controlled linear feedback shift register is proposed.
The post-processing can provide both randomness extraction and computationally secure speed increase of
input random data.
