Random number generation method and system

Abstract

The invention provides a random number generation method and system, and the method comprises the steps: obtaining the client data of a target client under a distributed network and an initial randomnumber generated through a random number generator, and enabling the distributed network to comprise a plurality of distributed clients; calculating the client data and the initial random number by adopting a preset algorithm to obtain a local factor which is an influence factor provided by the target client and used for calculating the random number; obtaining a global factor under the current distributed network, wherein the global factor is an influence factor generated by utilizing random numbers corresponding to all clients under the distributed network; and calculating the initial randomnumber based on the global factor and the local factor to obtain a target random number. On the basis of the random number generated by the random number generator, the generation factors of the tworandom numbers are added, so that the generated random number rule is difficult to crack, and the unpredictability and randomness of the random number are improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a random number generation method and system. Background technique [0002] Random numbers are widely used in information security scenarios such as generating encryption keys, HTTP digest authentication, and identity authentication. At present, random numbers generated by random number generators mainly include hardware-based true random numbers and software-based pseudo-random numbers. Count these two categories. However, hardware-based true random number generation is slow, which has an impact on server-side performance, and generally requires additional hardware devices. Therefore, it is rarely used in practical applications, and software-based pseudo-random numbers usually need to be based on a The initial random seed is generated. The random seed looks random but has a certain internal generation law, so that the final generated random number has a certain rec...
