Abstract

A random number generator based on a friction generator and a random number generation method, the random number generator includes: a friction generator, used to collect energy with random characteristics in the surrounding environment, and generate a first electrical signal with random characteristics, And an operation module, used to obtain a random number based on the first electrical signal, the random number generator has a simple structure and low cost, and generates a true random number.

Description

technical field [0001] The invention relates to a random number generator, in particular to a friction generator-based random number generator and a method for generating random numbers. Background technique [0002] With the increasingly higher requirements for information security in modern society, higher requirements are put forward for the confidentiality of cryptography. The basis of cryptography is random numbers. Traditional random numbers are generated based on computer software. A seed is generated by the computer, and then calculated by a program to calculate a series of random numbers. But this random number is pseudo-random, because the procedure for generating random numbers is fixed. With the increase of computer computing power, the key generated based on such random numbers will be easily deciphered, and the encrypted information will be easily leaked. Therefore, high information security requires random numbers to be highly reliable. sex. So far, random ...
