Hi folks,

I’ve noticed that 2 OIDF WG’s use HackMD to organize notes

https://hackmd.io/@oidf-wg-authzen

<https://hackmd.io/@oidf-wg-authzen%0b%0b>In the future can we also use it? It’s free for public teams https://hackmd.io/pricing#faq

## Notes

Paul: Thursday Sanders will present HDK(High deterministic Keys) Key management
and arkg (remote key generation) related to key attestation. Benefit regarding batch issuance.

https://github.com/openid/OpenID4VP/issues/141
Wallet backend and instance create the attestation, different pop per RP to avoid linkability.
Properties in the EU legislation state that the Wallet backend should not track which issuer the attestation is used and not know the exact credentials. How do we revoke credentials? Various options and discussions about it.
Next steps: More ideation around the above problems.

https://github.com/openid/OpenID4VP/pull/220
Hicham: In the query, is there a need to specify the number of credentials that should be returned? What if a lesser number of creds satisfy the query?
Daniel: This is the way to use AND OR in the rule.
Christian: Add boolean syntax example with the query for better understanding.
Paul: How do we render UI with that syntax?
Daniel: After processing the query with existing Creds, then list/show them in the wallet UI.
Joseph: Interesting edge cases. e.g. 2 passports which to use, parent-child use cases. UI challenges for these.
Next steps: Add more complicated examples in the new issue. If the general direction is ok then review/discuss, implement feedback, and land.

https://github.com/openid/OpenID4VP/issues/124#issuecomment-2250772504
Client ID security-related work. Matter will propose a solution approach on Tuesday.

Please review:

Best,
Rajvardhan
