Problems solved by technology

[0004] However, in actual scenarios, the service provider of the centralized random number generation service may conspire with the block generation nodes to cheat because of stakes, and affect the random number provided externally, thus putting itself in an advantageous position
It can be seen that in the blockchain system, the random numbers generated based on the centralized mechanism have low reliability and credibility.

Abstract

The present application discloses a random number generation method, device, device and storage medium, which relate to the field of computer technology, especially computer encryption technology and block chain technology, and can be used in cloud computing and cloud fields. The method is executed by the signature fragment generation node, and the specific implementation scheme is: obtaining an initial number; signing the initial number based on the local private key to generate a random signature fragment; transmitting the random signature fragment to the random number generation node, The random number generating node generates a threshold signature according to at least two random signature fragments, and generates a random number according to the threshold signature. This application provides a decentralized random number generation scheme with high reliability and credibility.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to computer encryption technology and block chain technology. Background technique [0002] In many business scenarios based on computer systems, there is often a need to use random numbers. For example, it is necessary to randomly select one of the candidates for task assignment, or in a lottery program, randomly select a number in the prize pool based on a random number. Therefore, a mechanism for generating random numbers is required. [0003] In the blockchain system, there are also requirements for the use and generation of random numbers. In the prior art, blockchain nodes can connect to a centralized random number generation service outside the chain to obtain random numbers. When using a centralized random number generation service to generate random numbers, users of other nodes in the blockchain can only unconditionally trust that the random numbers are indee...
