AI Technical Summary

Technical Problem

Due to the serialization of the entropy source, the existing true random number generator has low throughput and large resource overhead, so it is impossible to extract metastable state and jitter at the same time.

Method used

Using a high-throughput true random number generator based on MUX latch, two sets of MUX latch circuits and sampling circuits can achieve simultaneous extraction of jitter and metastable state, and output a random number with high throughput rate.

Benefits of technology

With less hardware overhead, a high throughput random number generation is achieved, which improves the randomness and robustness of the entropy source, and can acquire jitter and metastable state at the same time.

Abstract

The invention discloses a high-throughput true random number generator based on MUX latches, which comprises an entropy source circuit, a sampling circuit and a post-processing circuit, and is characterized in that the entropy source circuit comprises two groups of MUX latch circuits, and each group of MUX latch circuits comprises i-level MUX latch units; the D flip-flop is used for sampling the output in each stage of MUX latch unit; the post-treatment consists of an exclusive or chain. According to the method, the jitter and the metastable state are extracted at the same time under low hardware overhead, the high throughput rate is output, and good randomness and robustness are achieved.
