| Abstract | 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. |
