Entropy generation for a distributed computing system

摘要

In one embodiment, a method generates first entropy using a true random number generator in a management computer configured to manage a main computer in a computing device. The main computer controls a set of physical nodes including a set of services running in a set of virtual machines. The method then provides the first entropy to the main computer and the first entropy is combined with second entropy generated by the main computer to generate third entropy. The third entropy is provided to the set of physical nodes where the set of virtual machines access the third entropy via a hypervisor.

1. A method comprising:
generating a first entropy using a hardware random number generator in a management computer, wherein the management computer is configured to manage a main computer, wherein the main computer controls a physical nodes executing a virtual machine; transmitting, from the management computer, the first entropy to the main computer; combining, by the main computer the first entropy with a second entropy generated by the main computer to generate a third entropy; and transmitting, from the main computer, the third entropy to the virtual machine executing on the physical node; wherein the method is performed by at least one device including a hardware processor.
