CfP SPW 2017

26 oktober 2016

We are pleased to announce the twenty-fifth International Security Protocols Workshop, SPW 2017. This year the workshop returns to Cambridge, UK but now moves to the beautiful grounds of Trinity College, from Monday 20th to Wednesday 22nd of March 2017 (with Easter being 16th April).

This long-running workshop has hosted lively debates with many security luminaries (the late Robert Morris, chief scientist at the NSA and well known for his pioneering work on Unix passwords, used to be a regular) and continues to provide a formative event for many young researchers.

The post-proceedings, published in LNCS, contain not only the refereed papers but the curated transcripts of the ensuing discussions (see the website for pointers to past volumes).

Attendance at the International Workshop on Security Protocols is by invitation only. To be considered for invitation, please send us a position paper. Start writing now! "Writing the paper is how you develop the idea in the first place", in the wise words of Simon Peyton-Jones.

Our theme this year is "Multi-objective security". Security protocols often have more than one objective. For example, entity authentication holds only during the protocol run, but data implicitly authenticated by the session persists long afterwards. When are such temporal disparities essential and when are they inadvertent? Protocols may also have multiple objectives because they have multiple stakeholders with potentially-competing interests. Alice's access may be Bob's risk: how do we design protocols to satisfy both? How do we detect protocols serving one master better than the other? Do we even know where the protocol came from and what its authors' objectives are? How do they interact with the policies of resource owners? What about data provenance?

As usual, this theme is not prescriptive. It is not intended to restrict the topic of your paper, but to help provide a particular perspective and focus to the discussions, for any paper in some way related to security protocols. Consider the theme as a springboard, not a fence.

Our intention is to stimulate discussion likely to lead to conceptual advances, or to promising new lines of investigation, rather than to consider finished work.

Important dates (all in 2017)

  • 16 January: submission of position papers
  • 13 February: invitations to authors
  • 27 February: revised papers due
  • 27 February: registration deadline
  • 20-22 March: workshop in Trinity College, Cambridge



Position papers must be submitted through the form on the website by 23:59 UTC+0 on 16 January 2017.

To be considered for invitation, you must send us a first draft of a position paper by the published deadline. Short indicative submissions are preferred, preferably no more than 2000 words. You will have the opportunity to extend and revise your paper both before the pre-proceedings are issued, and after the workshop. At the workshop, you will be expected to spend ten minutes introducing the idea of your paper. This will be followed by a longer discussion.

Feel free to circulate this invitation widely, but do remember that the workshop has a limited size and in order to be invited you must submit a position paper (through the website, not by email please).
