EATF Research Interoperability Scheme

https://uri.eatf.eu/TrstSvc/schemerules/EATF-Research

This page states the rules of the EATF Research Interoperability Scheme, a research scheme profile operated by Tyche Institute (Estonian non-profit research association, registry code 80673227, Tallinn, Estonia) as part of the EATF — Agent Trust Framework research programme. Its purpose is interoperability experimentation for the endorsement of autonomous agent runtimes on European digital identity rails.

1. Trusted-list format

Trusted lists issued under this scheme conform to the structure, fields and status vocabulary of ETSI TS 119 612 V2.4.1. Service current status uses the standard URIs http://uri.etsi.org/TrstSvc/Svcstatus/granted and …/Svcstatus/withdrawn.

2. Service types

In addition to service types defined in ETSI TS 119 612, this scheme recognises the following scheme-registered service type (clause 5.5.1.0, value (d)):

3. Listing criteria

Before listing a service under the AgentRuntimeEndorser type with status granted, the scheme operator verifies that the service:

  1. publishes an endorsement policy stating what runtime attestation evidence it appraises and against which appraisal policy (e.g. IETF RATS, RFC 9334);
  2. demonstrates that endorsement attestations are only issued for runtimes whose attestation evidence was appraised as affirming, with replay and evidence-swap protections;
  3. demonstrates verification of the mandating party and of the delegated scope bound into each endorsement;
  4. protects its attestation-signing keys and publishes its service digital identity for listing; and
  5. supports revocation semantics — endorsements from a service whose status is changed to withdrawn must become rejectable by relying parties.

4. Relying-party rule

Relying parties under this scheme accept an agent-runtime endorsement only when its issuer is listed with the AgentRuntimeEndorser service type and status granted. A cryptographically valid signature from an unlisted issuer, or from an issuer listed under a different service type, is rejected.

5. Scope and legal effect

This is a research scheme: trusted lists issued under it exist for experiments, benchmarks and demonstrations. They are not EU Member State trusted lists, membership confers no legal effect and no “qualified” status under Regulation (EU) No 910/2014, and no production reliance may be placed on them. Tyche Institute publishes research specifications and reference implementations; it does not provide trust services.
