A hardware-based distributed multi-party random number generation method and system

Abstract

The invention discloses a hardware-based distributed multi-party random number generation method and system. The method includes the following steps: dividing the time slice into multiple periods, and sorting at least two random number generation nodes in the current period; The first random number generation node in the period selects a true random number and broadcasts it to other random number generation nodes; the current random number generation node receives and verifies the true random number broadcast by the previous random number generation node, and when the verification passes Then combine and sign the true random number generated by this node with the true random number broadcast by the previous random number generating node, and broadcast the signed true random number to other random number generating nodes; The mechanism of the protocol combines the random numbers generated by multiple nodes to generate the final random number, no longer relying solely on a specific hardware chip, which can prevent malicious parties from tampering with the random number without permission.

Description

technical field [0001] The invention belongs to the technical field of cryptographic random number generation, and more specifically relates to a hardware-based distributed multi-party random number generation method and system. Background technique [0002] As the basis of cryptographic protocols, random numbers are widely used in computer systems. How to generate secure and reliable random numbers has always been an active topic in academia and industry. Random numbers include true random numbers and pseudo-random numbers. True random numbers are generated using physical phenomena: such as noise, jitter, thermal noise, quantum phenomena, etc. using physical devices. These physical phenomena are theoretically uncontrollable, so The random number generated is unpredictable, such a random number generator is called a physical random number generator; the traditional random number generator based on computer hardware can be based on the hardware environment, such as CPU volta...

Problems solved by technology

[0004] Aiming at at least one defect or improvement requirement of the prior art, the present invention provides a hardware-based distributed multi-party random number generation method and system, no longer relying solely on a specific hardware chip, but each hardware chip generates The combination of true random numbers generates the final random number, and the random number generated by the combination inherits the advantages of uncontrollable, unpredictable, and non-repeatable true random numbers; more importantly, in the case of malicious parties, due to the use of The mechanism of reaching an agreement on random numbers between multiple parties can prevent malicious parties from tampering with random numbers privately, and its purpose is to solve the problem that the true random numbers generated in the existing technology cannot be verified
