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 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. Below is one example of how such an HA VID identifying an example company could be deployed based on a DID, a DNSSEC record (following the High Assurance DIDs with DNS RFC), and an X.509 digital certificate containing an LEI (following ISO 17442 Part 2).
...
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.
...
The deliverable of this Task Force is the High Assurance VID Specification, intended to create common patterns for establishing trust between different VID flavours. Accordingly, a VID must meet the requirements of a Verifiable Identifier (VID) as specified in the ToIP Technology Architecture V1.0 Specification and the draft ToIP Trust Spanning Protocol Specification. The requirements in this specification must interoperate with other ToIP component specifications as explained in the Evolution of the ToIP Stack.
