     ================
     *SUMMARY*
     
     1) Encryption software purchase process 
     2) Key update procedures
     3) Other items to modify in the addendum
     4) Review of Chapter 9 of the Manual
     5) Schedule for release of the new CommonLine Manual
     
     =================
     1)        *Encryption Software Purchase Process* 
     Scott reviewed license terms and and maintenance agreement.  He sent 
     these along to Karen Haney of NCHELP and Jason Swirtley, legal counsel 
     for PHEAA, for review. He has also requested clarification from Ed 
     Grace (of AT&T) as to whether the stipulations on transfer are 
     applicable to the distribution of SBS to schools.
     
     Ed Grace is revising the draft maintenance agreement to clarify the 
     description of Annual prepaid support.
     
     Scott has drafted a letter of intent and sent this to Karen Haney, Ed 
     Grace, and Jason Swirtley for review.
     
     A letter to members must be circulated to announce the decision and to 
     request they hold off contacting AT&T directly until processes are in 
     place.
     
     Ed Grace has requested members of the evaluation team return any media 
     and documentation that AT&T provided to support the evaluation 
     process.
     
     
     2)         *Key Update Procedures*
     Dennis Alley and others from TGSLC contributed their reflections on 
     several update options.  They are present on the archive under the 
     subject headings RFDC...
     
     a  Telephone confirmation
     When receiving a public key update the recipient must confirm the 
     update via telephone.  
     Advantage:
     Uses an independent channnel and thus provides positive confirmation
     Disadvantage:
     Very labor-intensive.  A Service Provider is likely to have many 
     (perhaps thousands) of partners to update.  This would mean each 
     update would cost Customer service as many phone calls.
     
     b  Automated confirmation
     This could take several forms
     i)an e-mail triggered by the update sent to the address from which the 
     update originated.  Presumably in this scenario, the update would be 
     suspended until the confirmation message was received.
     Advantages
     Less labor-intensive than scenario 1
     Disadvantages
     This creates an independent event but does not use an independent 
     channel, and thus it may not provide the desired level of security.
     ii) a fax triggered by the update sent to the fax number associated 
     with the entity performing the key update.  The fax would be signed 
     and sent back via fax.
     Advantages
     Uses an independent channel
     Disadvantages
     About as  cumbersome as scenario 1
     
     c  Key Server
     Dennis's scenario 2.  This was discussed a little last year and is 
     very well presented in Dennis's document.  
     Advantages
     Conceivable positive confirmation.  Theoretically a less complex 
     arrangement.  The key server would take responsibility for maintaining 
     the correct current key.
     Disadvantages
     Complexity in practice.  One entity must assume responsibility for 
     maintaining the service and providing 24x7, fail-over.  This does not 
     fit our current model.
     
     d  Embedding key in hardware lock
     Presented in Dennis's scenario 3
     
     e  UPS for key update
     Use UPS to ship the key update electronically.  
     Advantages:
     This would ensure authenticity.
     Disadvantages:
     It turns out that UPS charges $7/electronic document ($4/document for 
     volumes of 1000 or more documents).  This is an unacceptable cost
     
     f  Verisign for key update
     Use a certification service such as Verisign to authenticate the key 
     update.
     Advantages:
     This would ensure authenticity (at least to a satisfactory level)
     Disadvantages:
     Requires s/mime compliant mail systems to use (this would pose a large 
     extra burden on SBS developers).
     Some on the call have been frustrated with the difficulties obtaining 
     Verisign certificates.
     There is a cost to each party that uses a certificate.
     
     g  3DES to encrypt update key
     Encrypt the key update with a symmetric key known to all parties.
     Advantages:
     This poses another hurdle for intruders
     Disadvantages:
     This poses another hurdle for legitimate participants.  The hurdle for 
     intruders is not all that high
     
     h  Nothing beyond what we have already specified
     Keep the specification as it stands
     Advantages are obvious
     Disadvantages:
     The security exposure is a concern to at least one member
     
     Follow-up:
     1) The committee requests legal counsel from PHEAA and from NCHELP to 
     review our liability under scenario (h)
     2) Scott will inquire of Ed Grace whether AT&T has guidelines for use 
     relevant to our situation.
     
     3)         *Other Items to Modify in the Addendum*
     In the initial review, the team saw no need to change anything else in 
     the addendum except the references to PGP and NAI.
     
     4)         * Review of Chapter 9 of the Manual *
     Mike Brannon, technical writer for CommonLine, requested assistence 
     reviewing chapter 9 for accuracy (we are assuming CommonLine will 
     still be using CompuServe oldmail for some transitional period after 
     the new standard is implemented).  There were no volunteers.
     
     5)         * Schedule for release of the new CommonLine Manual*
     Mike Brannon stated the manual was scheduled to be released for 
     comment at the end of August
