Abstract

The invention discloses a random number acquisition method. The random number acquisition method includes the steps of acquiring public data at a specified time, wherein the specified time is pre-specified before itself; acquiring the hash value of the public data; based on the hash value, determining a random number seed; adding the random number seed to a preset random function to obtain a random number. The invention also discloses a random number acquisition device, a random number acquisition system and a storage medium. By the random number acquisition method, the public data of the specified time are random with time, and before the specified time, no one can predict the public data at the specified time; the public data of the specified time are subjected to hash calculation to obtain the hash value, and the random number obtained according to the random number seed determined by the hash value is open and fair; after the specified time, all persons can verify the random numberbased on the acquired public data of the specified time.

Description

technical field [0001] The present invention relates to the technical field of computer applications, in particular to a method, device, system and storage medium for obtaining random numbers. Background technique [0002] At present, the use scenarios and scope of random numbers are getting wider and wider, for example, they can be used in lottery, lottery and other scenarios. [0003] In the prior art, some data is pre-stored in a random number seed bank, and when a random number needs to be obtained, a piece of data is selected from the random number seed bank as a random number seed, and a random number is generated through a random function. [0004] In this method, the random number seeds in the random number seed library are relatively fixed, so that the generated random numbers are relatively fixed. If the random number seed library is obtained maliciously, the generated random numbers will be maliciously cracked, which cannot be guaranteed. Fairness and justice for...
