I took a look through my collection of Usenix proceedings. The paper
did not jump out at me. Considering the number of volumes that have
gone missing from my collection over the years, this is not surprising.

I did a search through the index at usenix.org but nothing obvious
turned up, although the following reference looks promising:

      Author: John Ioannidis
      Author: Matt Blaze
       Title: The Architecture  and  Implementation of Network Layer Security in UNIX
       Pages: 29-39
   Publisher: USENIX
 Proceedings: UNIX Security IV Symposium
        Date: October 4-6, 1993
    Location: Santa Clara, CA
 Institution: Columbia University
 Institution: AT&T Bell Laboritories

It's close to the timeframe I remember reading the paper (fall 1991 to
fall 1993).

While searching the Usenix index I noticed a couple of papers from the
Usenix Security V conference that looked promising. In particular:

      Author: Pau-Chen Cheng
      Author: Juan A. Garay
      Author: Amir Herzberg
      Author: Hugo Krawczyk
       Title: Design and Implementation of Modular Key Management Protocol and IP Secure Tunnel on AIX
       Pages: 41-54
   Publisher: USENIX
 Proceedings: 5th USENIX UNIX Security Symposium
        Date: June 5-7, 1995
    Location: Salt Lake City, UT
 Institution: IBM, Thomas J. Watson Research Center

Anyway, I'll keep digging and let you know what turns up.

If you decide to search your own collection, I vaguely remember
a paper about forwarding FIDOnet articles over the Internet being
in the same proceedings. (Don't ask me why ...)
