Abstract
Systems and methods provide for SPDM-enabled devices that conform to an SPDM specification. An SPDM-enabled device receives a request to provision a certificate chain on the device and sends an event notification message to a baseboard management controller. The event notification message indicates receipt of a request to provision a certificate chain in a slot on the SPDM-enabled device. The baseboard management controller evaluates the certificate chain against the device manufacturer's certificate profile policy. If the certificate chain is valid, then a validation successful message is sent to the SPDM-enabled device, which in turn sends a certificate provision response to a requesting device. If the certificate chain is not valid, then a validation failure message is sent to the SPDM-enabled device, which causes the SPDM-enabled device to enter a quarantine state.
