The High Assurance VID Task Force (HAVTF) is a task force of the ToIP Technology Stack Working Group. Its mission is to create a specification and implementation guidance for how the controller of a verifiable identifier (VID) can enable verifiers (aka relying parties) to have greater assurance in the integrity of that VID though mechanisms that enable the controller to bridge across different:
Verifiable Identifier (VID ) Flavoursflavours—including Decentralized Identifiers (DIDs), X.509 certificates and the Domain Name System (DNS) records—using mechanisms that records—to provide both high higher cryptographic assurance and strong stronger semantic linkage; and,
Trust Realmsrealms (aka trust domains) , to show how contrasting approaches to VID-based trust architecture can share common trust roots to establish interoperability.
...
so the same VID can be verified from more than one trust roots to increase human trust and enhance interoperability.
This “bridged approach” to VIDs will lay the foundation for High Assurance (HA) VID Profiles that remain agnostic to the underlying VIDcan work with many different types of VIDs. This approach allows decision-makers to choose the most suitable VID for specific contexts and purposes without foregoing interoperability between VID systems. By designing a framework that supports and acknowledges theunique benefits of each VID flavour, different flavours can co-exist rather than compete. This should result in a more robust, scalable, flexible and high assurance architecture for the implementation of ToIP digital trust ecosystems.
