A secure device identifier (DevID) is a cryptographic identity bound to a device used for assertion of the device's identity. ISO/IEC/IEEE 8802-1AR:2014 specifies - globally unique per-device identifiers and the management and cryptographic binding of a device to its identifiers, - the relationship between an initially installed identity and subsequent locally significant identities, and - interfaces and methods for use of DevIDs with existing and new provisioning and authentication protocols.
