Pseudo-random number generation method and device and server

Abstract

The invention provides a pseudo-random number generation method and device and a server. The method comprises the steps of acquiring preset seed data, wherein the preset seed data comprise a pluralityof random number seeds, and each random number seed carries a preset secret key; calling and performing multiple rounds of preset processing on the preset seed data according to a preset instructionset to obtain a plurality of pseudo-random numbers, with the preset instruction set being an instruction set preset in the processor, and the preset processing being parallel processing for a plurality of random number streams corresponding to the plurality of random number seeds. In the embodiment of the specification, a plurality of random number seeds are spliced to obtain seed data. Parallel preset processing is carried out on the random number streams corresponding to the plurality of random number seeds by calling a preset instruction set stored in the processor and taking the seed datacontaining the plurality of random number seeds as a processing unit, so that a plurality of pseudo-random numbers are obtained, and the plurality of pseudo-random numbers can be efficiently and safely generated.

Description

technical field [0001] This specification belongs to the technical field of the Internet, and in particular relates to a method, device and server for generating a pseudo-random number. Background technique [0002] In many data processing scenarios, it is often necessary to use a large number of pseudo-random numbers. For example, in transaction data processing, in order to ensure data security during transaction data processing and prevent transaction data from being stolen or tampered with, a large number of pseudo-random numbers are often used for mask processing. [0003] However, the existing methods for generating pseudo-random numbers often generate pseudo-random numbers through serial processing, that is, each round can only execute instructions for one pseudo-random number stream and perform corresponding processing. Therefore, based on the existing method, there are often technical problems such as low pseudo-random number generation efficiency and inability to m...
