### [🔒 Wallet Security WG](https://github.com/decentralized-identity/wallet-security/blob/main/agenda.md)

* Specify requirements for Wallet Authentication issuance
Wallet Authentication VC Scheme
Challenge-response Aries RFC Draft
Differences to cloud scenario
- Discussion of above sequence diagram
- discussed attestation formats
- learn from or use https://w3c.github.io/webauthn/#sctn-defined-attestation-formats ?
- next steps:
- fix sequence diagramm
- standardize credential presentation with challenge response
- review device binding lifecycle from last session
- discussion on embedding keys or dids of keys into the VC
- identify building blocks and match existing components
4. discussion to standardize in Aries RFC
- review and discuss the lifecycle (commenting in google docs)
- https://docs.google.com/document/d/1iJAB7VRe1P4wEaBOAb-g8Fn4JvyMXpkpEMkK06U1Qh4/edit#heading=h.65alklkg59te
- whats (in) the trust registry?
- list of multiple wallet issuers and their certification status
- is data stored in a (global) trust registry and/or a verifiable data registry?
- which verifiable data registry if wallet supports multiple DID methods?
- is there a possiblity for a global wallet trust registry?
- country-specific wallet trust registry?
- trust registry bound to the legal framework?
- e.g. Pan Canadian Trust Framework specifies a list of wallets that are eligible and issuers can trust all wallets from this list
- separate trust registry in eIDAS etc..
- content
- wallet isser and his legal representation
- contact information
- versions
- certification body
- certification status/expiration
- discussion on embedding keys or dids of keys into the VC
- goal to rotate key in "lost phone" case
- neccessary for high-security usecases - you need to start again
- did document layer adds lots of complexity
- migration to new phone scenario that proves the old credential in automatic exchange for a new one contacting the issuer
- fear of adding complexity for little benefit
- next steps:
- Specify requirements for Wallet Authentication issuance
- Wallet Authentication VC Scheme
- Challenge-response Aries RFC Draft
- Differences to cloud scenario?
* Discussion and planning for device binding & wallet authentication
- [Aries RFC standardization path](https://hackmd.io/j7tSL_QPTPiaPhZh_xLDvA) :
- possible combination of both
* roadmap to standardize in Aries RFC
* OpenID Connect outlook
-[ Document shared and presented by Sebastian:](https://hackmd.io/@sbickerle/SyLsYsmZq)
- challenges and solutions on device binding presentation as attachments
- attachments for Present Proof Protocol 1.0 & 2.0
- discussion requires a full lifecycle/full walkthrough(mobile now, cloud later):
- 0. Wallet Authentication scheme is defined
- 1. Wallet Authentication VC
- 2. Issuers are issuing a device-bound credential
- 3. Verifier proofs a device-bound credential from a trustworthy device
- later: wallet detects changes and requests a refreshed wallet authentication VC

### [☂️ InterOp WG (cross-community)](https://identity.foundation/interop/) ###
* Upcoming: *9th of Feburary 2022 - US Time*
* Bob Blakely is coming to share with us a reflection of the SAML interop work.
* *2nd Feb 2022*
* Dmitri Zagidulin presented his **QR Code part 2**, see agenda 8th of December for context
* Group is preparing for real interop at IIW 34 - April 26th-28th
* Our perspective on potential interop targets: We believe that it could be possible to have interop testing around JSON-LD ZKP with BBS+.
* We believe test suites should be built, how?
* What is needed to get to JSON-LD ZKP with BBS+ interop? Where are they bottle necks? What are the key groups that are or will be working on key parts.
* Potential interop targets: could it be possible to have interop testing around JSON-LD ZKP with BBS+?
* Exchange protocols: does WACI-PEX (designed to bridge between the Aries world and SVIP world) have potential as the exchange protocol?
* Prospective Scope
* WACIPex
* JSON-LD
* ZKP with BBS+
* Profile of interoperability, it has been used alot of before to land something acknowledgeble. Profiles are useful to drive interoperability to a flexible spec that can drive things forward.
* What other profiles to others have? German community says it is a bit complex question. Issues with BBS+ signatures as of today.
* Relevant links: [AIP Interoperability Testing](https://aries-interop.info/)
* [AIP profile v1.0](https://github.com/hyperledger/aries-rfcs/tree/main/concepts/0302-aries-interop-profile#aries-interop-profile-version-10)
