(perhaps point that a third option would be linking or referring to some public evidence outside the ledger??) * Election Use Case * Ray * Working on election data use case * Requires data outside of the ledger * Also requires air-gap support * Hannes: * makes sense to have several paragraphs written about it * useful to document somewhere even if we put it on hold for now * Ray: * would need to summarize; currently too detailed * Roy: * Would love to see full document * Non-opaque well known statements (Henk) * Relationships between statements * Links to external payload * Audit use case * What should be exposed during audit? This will help inform what data is stored on ledger, which is external (Roy) * Sigstore Use Cases (Hannes) * Link posted to mailing list ahead of the holidays * Writeups by different companies * Would be good to cover these in our use cases * Key Management, Air-gapped scenarios * Can someone review and ensure these are covered in our document? * Goal data for finishing use case document? * Should we set a date? (Dick) * Proposed date - mid-February (Hannes) * Henk: agree with mid-February; needs to switch to another project by then * Dick: agree with mid-February # Additional Topics for today's meeting {#additional-topics-for-todays-meeting} * Sigstore use cases (proposed by Hannes) * Proposed new use case (proposed by Hannes) * Workback schedule for IETF 116 (proposed by Roy) * Terminology document (proposed by Roy) # Threat Model {#threat-model} * Henk to ping Brendan Moran to help with threat model * Hannes - sensible to include threat model in architecture document # Material for IETF 116 (Roy) {#material-for-ietf-116-roy} * Summary * Use Cases * Threat Model * Terminology * Jon * Use Cases * Threat model * Roy * What will the slides be? * Who will work on each slides? * Posters * Hannes * Jon/Hannes to send email to see who will attend in person and remote * Remote attendance for IETF 116 may be challenging give time zone * Yogesh * Terminology should also be a topic for IETF 116; discussion with Cedric and Antoine before the holidays, should be able to wrap up in the next several weeks * Will take an action to summarize current status and open items and share with SCITT mailing list # Terminology {#terminology} * Monty * do we have a place to describe definitions of concepts we need describe terms for? Once we have a list of definitions, we can define terms * Is there method for discussion of terms * Hannes * Mailing list * Yogesh * All terms we use should be in the terminology section of the SCITT architecture document # Thursday technical meeting {#thursday-technical-meeting} * Thursday bi-weekly meeting - is this still happending? (Ray) * Hannes: No. The only formal meeting is this one on Mondays; there may be ad-hoc small group meetings on specific topics. * Yogesh: The Thursday meeting (from his outlook calendar) has now been cancelled
