Previous Minutes

Ray moved and Dave C seconded the approval of the December 10, 2012 minutes. The motion was approved.

Action Item Review

Steven reviewed the open action items.

Liaison Reports

P1800 waiting for publication P1076 still not active on encryption issues

Inter-operability

John commented on the encoding discussion, indicating concerns with line length and byte count for the raw encoding. Steven mentioned that base64 represents a family of encodings that differ in the line length and padding conventions. John suggested that adding the additional normative references to the MIME RFC would help bring us into alignment with the expected behavior for base64 and simplify our recommended use model. The line length and byte count definitions may still be required for other encodings, but base64 could be required to match the MIME standard. Dave G expressed concern about making those parameters optional, and John suggested that they be ignored if supplied for a base64 encoding.

John suggested that base64 be assumed as the default if not specified in the encryption envelope. The decryption envelope should require the encoding to be explicitly specified. Dave G suggested that we explicitly state that encryption envelopes are expected to be inter-operable for any conforming encryption tool. The candidate requirement for this is simplifying key references through external representation. The key certificates provide a standard specification for keys that can be referenced using the existing pragma syntax via key_owner and key_name.

License Management

Dave C asked about the status of distributing a reference implementation for license management. Steven reported that the current license status for materials distributed with a published standard are not friendly to those who want to re-distribute as part of a conforming implementation. Dave G will be investigating how to distribute under an open-source license.

Key Management

No discussion

Rights Management

Dave G is looking for feedback on the current draft, particularly on conditional rights syntax and digest calculation issues.

Common Rights and Visibility
