Abstract

An Information Handling System (IHS) includes multiple hardware devices, and a baseboard Management Controller (BMC) in communication with multiple hardware devices of the IHS. The BMC includes executable instructions for transmitting a broadcast message to the hardware devices in which the broadcast message has a block of data including a digital signature of the BMC. Each of the hardware devices that receive the broadcast message are configured to transmit a broadcast acknowledgment message to the BMC. Using the block of data, the BMC and hardware devices may perform a mutual consensus procedure with other using a cryptographic hash function of the block of data.
