Abstract

This application provides a true random number generation circuit, which continuously generates and outputs random bits through an entropy source module, then uses a sampling module to collect and output random bits according to an external clock signal to improve the randomness of the output random bits, and finally uses an encryption operation module to perform shift and logical combination operations on the random bits to ensure that the output random bits meet both the quantity requirements and the randomness requirements, thereby obtaining a high-quality random number sequence.
