Platform integrity verification
Monitoring the health status of platforms
Platform integrity verification allows a remote party to verify the health status of a platform. The requester can then use this information to decide whether to grant access to confidential information, for instance. This functionality enhances system security by complementing user and device authentication with an additional platform health check.
Platform integrity verification starts by measuring the health of the device platform, either statically when it boots or dynamically after the system has booted. These health measurements can be securely sent to a trusted remote party for verification or they can be verified locally. If malware is detected, the infected device can be quarantined and the device can be restored to a clean and functional state.
IoT-ready verification capabilities
As part of its platform security management services, Infineon delivers an OPTIGA™ TPM that can be used to store platform integrity values and support platform integrity verification protocols. While multiple Infineon products can be used for this purpose, OPTIGA™ TPM includes native support for integrity verification and supports integration of this feature, which is available for many popular IoT device operating systems. For this reason, OPTIGA™ TPM is the best match for this security application.
