Problems solved by technology

The random numbers generated by related technologies are easily controlled by a malicious behind-the-scenes opponent, so the randomness cannot be guaranteed
In this way, it is very unfavorable to users of random numbers, for example, the interests of random number users will be damaged due to controlled random numbers

Abstract

The invention discloses a random number generation method and device and a storage medium, relates to the field of computers, and can ensure that the generated random number has randomness. The randomnumber generation method comprises the steps that a target node obtains a first random number and a first private key for the target node; The target node generates a second random number based on the first random number, the first private key and a first deterministic function; And the target node broadcasts the second random number. This application is used for random number generation.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a serial random number generation method, device and storage medium. Background technique [0002] Random numbers are the result of specialized random experiments. Random numbers are used in different techniques of statistics, such as when drawing representative samples from a statistical population, in the process of assigning experimental animals to different experimental groups, and so on. The most important feature of a random number is that the subsequent number has nothing to do with the previous number when it is generated. [0003] There are many different ways to generate random numbers. The random numbers generated by related technologies are easy to be controlled by a malicious behind-the-scenes opponent, so the randomness cannot be guaranteed. In this way, it is very unfavorable to users of random numbers, for example, the interests of users of random n...
