An Information Handling System (IHS) includes multiple hardware devices, and a baseboard Management Controller (BMC) in communication with the plurality of hardware devices. The BMC includes instructions for executing a bootloader to verify an integrity of a first firmware stack, and boot the first firmware stack on a first processor. Once booted, the first firmware stack verifies the integrity of a first code segment on a second processor that is also used to execute a custom BMC firmware stack. The first code segment is executed to verify the integrity of one or more vendor supplied code segments executed on the second processor.

Trust verification system and method for a baseboard management controller (BMC)

An Information Handling System (IHS) includes multiple hardware devices, and a baseboard Management Controller (BMC) in communication with the plurality of hardware devices. The BMC includes instructions for executing an assistance application (APP) in an untrusted domain of the BMC. The assistance APP configured to monitor a custom BMC firmware stack executed in the untrusted domain. The instructions are further executed to verify an integrity of the assistance APP from a trusted domain of the BMC by encrypting communications between the trusted and untrusted domains using an encryption key that comprises a function of a time counter value.
