International Workshop on Security Protocols
Cambridge, England
25 - 27 April 2001

You are invited to consider submitting a position paper to the Ninth Cambridge International Workshop on Security Protocols. The workshop is jointly sponsored by the Cambridge University Computer Laboratory and Centre for Communications Systems Research, and held at Microsoft Research Limited, Cambridge. Attendance is by invitation only, and in order to be invited you must submit a position paper.

Theme

This year's theme is "Mobile Computing vs Immobile Security".

This theme includes (but is not limited to):

We invite you to consider these issues. As usual, we don't insist that position papers relate to the current theme in an obvious way. Our experience is that the emergence of the theme as a unifying thread takes place during the discussions at the workshop itself. The only pre-condition is that position papers should concern some aspect of security protocols, which may, but need not, involve cryptography.

Our intention is to select the most interesting papers for presentation at the workshop: those which will stimulate discussion likely to lead to conceptual advances, or to promising new lines of investigation, rather than papers which merely describe a piece of finished work.

Background

The Cambridge Workshops on Security Protocols originated in informal discussions between members of the University of Cambridge Computer Laboratory and others with wide interests in security issues of distributed computer systems.

The purpose of the Workshops is to bring together a relatively small number of researchers and leading-edge practitioners working in the field to discuss new ideas and developments in distributed systems security. Each workshop concentrates on a particular theme within this wider context, in order to stimulate and focus discussion.

Themes of past workshops have included, for example: reasoning about cryptographic protocols, requirements of data integrity compared to requirements for confidentiality, trust and delegation. The traditional emphasis at the Computer Laboratory has been on real-world systems, and there has been a consistent and deliberate leaning towards systems engineering and implementation aspects. Theoretical contributions presenting novel techniques that address real-world problems have also been very welcome.

The proceedings of previous workshops in this series have been published by Springer-Verlag as Lecture Notes in Computer Science. The 2000 Proceedings are currently being edited for publication, but the 1999 Proceedings are available as LNCS 1796, and the 1998 Proceedings as LNCS 1550. If you have not previously attended the Security Protocols Workshop, you may find it helpful to refer to these to get an idea of the flavour.

Workshop Participation

Participants are assumed to have knowledge of cryptographic algorithms and techniques, but the primary emphasis of the workshops is on the environment in which such protocols operate and the nature and interactions of the systems components which implement them.

The objective of the workshop is to provide a forum for the discussion of new ideas and approaches that are still in the process of formulation, yet sufficiently developed to benefit participative discussion with knowledgeable peers.

The workshop will be organised in related sessions with short (ten minute) individual presentations of position papers being the starting point for a wide-ranging informal discussion. As in previous years, it is our intention to include edited transcripts of these discussions in the Proceedings of the Workshop.

Initial submissions to the workshop should take the form of a position paper (preferably no longer than about 2 - 3,000 words please) exploring current limits and deficiencies in the area rather than being completed research due for publication. Reasoned controversy is welcomed. You will have the opportunity to revise your position paper prior to publication of the proceedings.

All submissions should be made initially to Michael Roe and marked "2001 Protocol Workshop". Please ensure that we have a first version of your position paper by January 31, as we intend to issue invitations during February.

Workshop Fees

We need to cover the costs of organising the workshop, but do not intend to make a profit. Last year a nominal contribution of 180 pounds sterling per person was requested to cover expenses. We intend to prepare pre-proceedings of the meeting which will be distributed to participants at the workshop.

A workshop dinner will be arranged at one of the Cambridge Colleges. This has in the past proved to be a productive and entertaining adjunct to workshop, as well as giving spouses and partners an opportunity to become involved in our general discursions. The cost of the dinner for participants is included in the workshop fee, although there will be an additional cost for guests (on the order of 30 pounds sterling).

Enquiries

If you have any enquiries about the workshop then please contact one of the organizing committee.

To be considered for invitation, you must submit a position paper by 31 January. Please make an initial response as soon as possible, even if it is only to say that you are potentially interested, to:
