With: John Krienke, Nate Klingenstein, Tom Scavo, IJ Kim, Joe St Sauver

SHA-2 Update

Joe St Sauver gave an update of the certificate service move to SHA2

  • SHA2 deployed for SSL/TLS
  • Some issues with the way Microsoft interprets SHA 512 intermediate certs, so using SHA 384.
  • Activated for client certs
  • Comoto working on activation for extended validation certs
  • Code-signing certs – can have either SHA1 or SHA2 but not both. Moving to SHA2; those needing SHA1 can obtain by asking Comodo for an exception

R&S Survey

A survey was sent to site admins and execs regarding use/potential use of R&S and deployment of global R&S. Tom Scavo presented the results to date and is working to analyzing those and responses to open-ended questions.


There was a discussion about TIER – specifically about two documents linked from the agenda:

The Case for TIER was presented to 42 CIOs at the EDUCAUSE annual meeting. All 42 voted in favor of the plan and 20 agreed to funding the capital plan (three additional schools later committed to funding.

There is a window of opportunity to help shape TIER, particularly through the State of TIER document. There was general discussion about what the document means for InCommon, with such questions as:

  • Is there a hub-and-spoke model implied?
  • Is the certificate service moving to NET+ and, if so, what are the workload and financial implications for subscribers?
  • What is the proposed governance model for TIER?
  • What will be done to make things easier and better for SPs?
  • Is the proposed funding adequate for both development and maintenance?
  • What are the implications of the emphasis of the Globus/Nexus model and how does this dovetail with the IdP of Last Resort WG work?

TAC members are encouraged to send questions and comments to the TIER architects list to spur discussion.


Steering has developed an eduGAIN working group. Steve Carmody and Warren Anderson have joined to represent the technical side. There is a punch list that will include items for TAC to discuss.
