Abstract

The invention provides a BMC-based random number generation method and system. The method comprises: S1, generating system current time value data by using a real-time clock module; S2, transmitting the current time value data to an SM3 algorithm module, supplementing 0 at a high position of the time value data through the SM3 algorithm module, and enabling the time value data to reach 512 bits; and S3, carrying out operation on 512-bit clock data per second to generate a 256-bit hash value, and taking the hash value as a random number. According to the method and the system, a random number generation function is realized through a software mode. The system current time value data generated per second by the real-time clock module is transmitted to the SM3 algorithm module. The SM3 algorithm module generates a 32-byte hash value per second as a random number, so that generation of random number is realized, and requirement of using random number by BMC is effectively met. According tothe technical scheme, the generated random number is high in stability, hardware resources of a server mainboard is not occupied, and the system is free of additional cost and is high in operability,and the design flexibility is improved.

Description

technical field [0001] The invention relates to the technical field of server boards, in particular to a BMC-based random number generation method and system. Background technique [0002] The BMC (Baseboard Management Controller, Baseboard Management Controller) has been widely used in the field of servers at present, and uses virtual keyboards, interfaces, mice, power supplies, etc. to provide remote management functions for servers. Users can remotely monitor the physical characteristics of the server through the network port of the BMC, such as the temperature, voltage, fan working status, power supply, and chassis intrusion of each component. [0003] A random number is a random sequence, usually generated by a random number generator. The characteristic of random numbers is that the next number generated by the random number generator has no relationship with the previous number. Random numbers have been widely used in communication, measurement, acoustics and other ...
