IESHG - Profile for IDevIDs for devices in the Industrial Automation domain

IDevIDs, standardized in IEEE 802.1AR, are secure identifiers for devices. This whitepaper proposes a profile for IDevIDs for devices in the Industrial Automation (IA) domain (IA devices).
The profile intends to facilitate an interoperable use of IDevIDs across different IA device manufacturers, different standards development organizations (SDOs), different solution providers, and for different use cases. Concretely, the proposed profile:

• recommends IL Strings (in accordance with IEC 61406) as a common, instancespecific, and globally unique device identity in IDevIDs, and
• provides a shortlist of asymmetric cryptographic algorithms for IDevIDs, seeking to minimize mismatches in algorithm support between devices possessing IDevIDs and verifying entities.
