S/MIME Minutes - 69th IETF, Chicago


Agenda bashing, blue sheets, etc.

Status review by Sean Turner
2 drafts with RFC editors (symkeydist, esscertId)
5 drafts passed WG last call (rsa-kem, ibearch, bfibecms, cms-auth-enveloped, aes-ccm-and-gcm)
ID in WG (Multiple Signatures Attribute, CMS Advanced Signatures, SHA2 Algorithms)

Jim Schaad discussed the Multiple Signatures draft
Moved hash attacks text to appendix
Fleshed out unfinished text in section 5
Draft -02 sent to the queue 
Remaining items include getting an OID for ASN.1 module, fleshing out security considerations
Expect to be done with remaining items by next meeting

Sean Turner discussed the status of the CMS Advanced Signatures draft 
Last call completed more than a year ago, but still not in IESG review (contrary to slides)
Incorporating comments on hash calculation and procedures for zero hash of SigPolicy
Draft -03 will include these revisions
Will post new Internet Draft after the meeting
Another WG last call will be completed since prior one was more than a year ago (direction of Tim Polk)

Sean Turner discussed the SHA2 Algorithms draft
Draft -01 in progress
Next version will add signature algorithm conventions for DSA with SHA-224 and SHA-256,
RSA with SHA-224 thru SHA-512, and ECDSA with SHA-224 thru SHA-512

Jim Schaad discussed ASN.1 2002 tutorial
Jim and Paul Hoffman secured funding to develop ASN.1 compiler (newer than '88)
Expect it will be ready end of 2007
Looking for input on which features to include and which to exclude
General consensus is that concept is not controversial
Anyone with requests for specific compiler features should get in touch with Jim or Paul
Message will be posted to ML to encourage additional discussion

Wrap-up discussion
Plans to put working group in hiatus after Vancouver (moving towards closure)

Question regarding rsa-kem draft
Status is that ASN.1 does not compile
Should not go forward ASN.1 is fixed
