---+++ Minutes

---++++ Attendance/Quorum

We have 5/6 eligible entities, and have a working quorum.

---++++ Patent Policy

The [[http://standards.ieee.org/board/pat/pat-slideset.pdf][Patent slides]] were offered for review.

No new claims were disclosed at the call for essential patent claims.

---++++ Agenda Approval

Motion by Jarek, seconded by Dave G. Motion is approved.

---++++ Previous Minutes
Ray moved and Jarek seconded the approval of the [[P1735Minutes2011June13][June 13, 2011]] minutes. The motion was approved.

---++++ Action Item Review
Steven reviewed the open action items.  

---++++ Liaison Reports
No new activity.

---++++ Inter-operability
John noted that the remaining open issues are related to validation, and that we should decide whether this is still a priority.

---++++ License Management


---++++ Key Management
Steven reviewed the changes on the recommendations page.  John noted that the DER recommendations should apply to Standard Key exchange, and under Basic Key exchange the recommendation applied to every out-of-band exchange.

---++++ Rights Management
John asked about key_block structure for tools that didn't implement rights, and Dave suggested that the absence of a =key_content= pragma in version 2 could indicate equivalence with version 1 key blocks.

John asked about tamper-resistance for rights-blocks in all tampering scenarios. Randomly generated, one-time use, session keys become mandatory for making rights tamper-proof.

Steven noted that the control block structures in an encryption envelope did not mark the boundaries over which the digest would be calculated. The working group discussed the differences between the VHDL and SystemVerilog specifications, and how they affected the protection semantics for key_blocks and data_blocks. Steven noted that we need to balance the needs of IP Authors and Tool Implementors in deciding the rules for composing relationships between key, control, and data blocks.

Dave polled for objections to the decryption envelope work presented to date. There were no objections to the direction of work on the control block structure for decryption.

---++++ Work Plan


---++++ Other Business


---+++ Next Meeting

The next [[P1735MeetingInfo][P1735 meeting]] is scheduled for July 11, 2011 at 15:00UTC.
