Long-term Archive and Notary Services (LTANS) Working Group Charter Review

Administrivia Chairs –Tobias Gondrom and Carl Wallace Security Area Directors –Russ Housley and Steve Bellovin Security Area Advisor –Russ Housley Mailing List –Discussion: –To Subscribe: In Body: subscribe –Archive: Web site – Hosted by Peter Sylvester Contains charter, related documents, milestones, etc.

WG Description Overall aim of the WG is to define mechanisms to support the ability to prove the existence and validity of data over long periods of time –Made difficult by certificate expiration or revocation, cryptographic weakness, etc. Problem to be addressed in two parallel efforts –Data structures, e.g. archive time stamps –Protocol for interacting with archive service Build on and reconcile existing work –RFC 3029 (DVCS), RFC 3161 (Timestamp protocol), RFC 3126 (long-term signature formats), ATS (Archive Timestamps Syntax), TAP (trusted archive protocol), etc. –PKIX, XMLDSIG, SMIME –ArchiSig, OpenEvidence, USMC PK-E

Why ? Timestamps are not enough –What happens if used ts-algorithm gets weak ? –What happens if used Hash-algorithm is no longer reliable ? What when certificates run out / are no longer available ? OCSP from trust-center no longer available ?...

Lifetime of signed data CreationSigning Storage Short/long-Term Normal storage Resign / generate Trust Trusted Third Party / Notary – individual basis Mass storage and re-signing without trusted third party

First Steps Trusted Archive Protocol (TAP) Archive Time-Stamps Syntax (ATS) Data Validation and Certificate Server Protocols (DVCS) RFC 3029 (DVCS), RC 3126 (ETSI)

Approach Define requirements Solve problem, find best solution decided on base of requirements Make solution

Timeline 1.Archive signed data 2.Notary services
