Abstract
A BIOS/OS key provisioning system includes an NVMe storage device coupled to a server device via a network. The server device includes an operating system engine and a BIOS engine. Subsequent to a current initialization of the server device and prior to an immediately subsequent initialization of the server device, the BIOS engine retrieves a key from a key storage subsystem and stores the key in a BIOS memory subsystem. When the BIOS engine receives a current key request that identifies the key from the operating system engine and determines that the key stored in the BIOS memory system has not previously been accessed subsequent to the current initialization and prior to the subsequent initialization, it provides the key from the BIOS memory subsystem to the operating system, and prevents the key from being provided from the BIOS memory subsystem in response to any subsequent key request.
