Problems solved by technology

In most cases, it is difficult for an attacker to crack the cryptographic algorithm directly, but by using devious attack methods such as guessing the secret random number used in the cryptographic algorithm, the entire cryptographic system can be broken through the secret random number.

Abstract

The invention discloses a random number generation method, a random number generation device and a computer storage medium, and the method comprises the steps: generating a first random number by using a first random signal; Generating a second random number by using the second random signal; Wherein the first random signal and the second random signal are signals generated by different signal sources; And performing setting operation on the first random number and the second random number to obtain a required target random number. Through the mode, the generated random number has irreversible, unpredictable and unrepeatable properties.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a random number generation method, a random number generation device, and a computer storage medium. Background technique [0002] Random numbers are widely used in key generation, digital signature, key agreement, etc., and are very important in cryptographic applications. The security of random number generation methods directly affects the security of cryptosystems. In most cases, it is difficult for an attacker to crack the cryptographic algorithm directly, but by using roundabout attack methods such as guessing the secret random number used in the cryptographic algorithm, the entire cryptographic system can often be broken by obtaining the secret random number. [0003] Random number generation includes two types: true random number generation and pseudo-random number generation. True random number generation is usually based on physical entropy sourc...
