       Report  of the Interim Meeting of ISO/IEC JTC1/SC6
                      Lower Layer Security
                    London 8-12 February 1993

A.   General

     The interim meeting of SC6 Working Groups (Lower Layer
     Security) was held at BSI in London on 8-12 February. Mr.
     Richard Thomas (BNR, Canada) presided over this meeting. The
     minutes of this meeting are contained in document SC6 N7962.

B.   U.S. Delegates

     Dale Walters (NIST)
     Steve Sherman (Hughes)

C.   Recommendations

The following resolutions were all unanimously approved at a joint
WG1, WG2, and WG4 plenary.

1) The Lower Layer Security Model (This had been called a
Guidelines document prior to this meeting) has been registered as
a PDTR (type 3) as authorized by the SC6 San Diego resolution #108.
This is a three month ballot. The US comments concerning LAN
security were incorporated into this revised version.

2) Five documents were circulated to SC6 member bodies with
comments due by  July 30, 1993.

     a)   N7953 Use of NILS with NLSP-CO
     b)   N7954 Application of generic abstract security interface
          for both TLSP and NLSP
     c)   N7955 A contribution capturing the ad hoc groups
          understanding of Protection Qos as it relates to security
          policy
     d)   N7956 A Lan security requirements document requesting
          comments on whether the LAN security protocol (developed
          by IEEE) or NLSP should be used to protect LAN data.
     e)   A US contribution on managed objects for NLSP and TLSP

3) A liaison statement to CCITT was sent stating that since the
NLSP and TLSP amendment ballots will not close before the next
CCITT meeting, SC6 proposes that the joint publishing schedule for
these two documents be postponed until early 1994. 

4) Three liaison contributions were sent to other ISO committees.
 
     a) N7958  A document concerning Security of OSI Systems
     Management was forwarded to SC21/WG4.
     b) N 7960 A document concerning Security information objects
     was forwarded to SC27/WG1.
     c) N7961 A document concerning QoS, Definition of the security
     abstract interface, and OSI Reference Model was forwarded to
     SC21/WGs 1 and 8.


D.   U.S.Positions

There were no cases in which the Lower Layer Security ad hoc group
approved a recommendation that did not agree with the U.S. position
on the corresponding subject.

E. Actions Required by X3S3.

X3S3 will be requested to review and approve proposals from its
task groups for responses to the security issues identified in the
above mentioned documents plus the ballot comments on DIS NLSP and
the DAM 1 to TLSP. The two ballot responses will be handled at the
next X3S3.3 meeting in late April with the other documents handled
in time for the next SC6 meeting.
