The twenty-third International Workshop on Security Protocols will
take place from Tuesday March 31st to Thursday April 2nd, 2015 at
Sidney Sussex College, Cambridge, England.

As with previous years, attendance at the International Workshop on
Security Protocols is by invitation only. In order to be invited you
must submit a position paper. You are therefore encouraged to consider
submitting such a paper.

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 again after the
workshop.

To be considered for invitation, you must send a first draft of a
position paper to James Malcolm (j.a.malcolm@herts.ac.uk, telephone:
+44-1707-284-310) by January 7th 2015.

The theme of this year's workshop is "Information Security in Fiction
and in Fact".

Fiction can become fact: mobile phones look and operate the way they
do because the engineers who design them watched Star Trek when they
were children.

But yesterday's facts also become today's fictions: today most privacy
protocols are theatrical performances, albeit not always playing to a
live audience.

How is information security handled in fiction, and what aspects of
this could we emulate in next-generation technology if we tried? And
how much of what we do now should be relegated to writers of
historical fiction?

This theme is not intended to restrict the topic of your paper, but to
help provide a particular perspective and to focus the discussions.
Our intention is to stimulate discussion likely to lead to conceptual
advances, or to promising new lines of investigation, rather than
merely to consider finished work. At the workshop, you will be
expected to spend about ten minutes introducing the idea of your
paper, in a way which facilitates a longer more general discussion.
There are a few more details at: http://spw.stca.herts.ac.uk/.

The exact cost of the workshop is to be determined, but is likely to
be in the region of 300 UK pounds. Registration includes lunches and
a formal dinner in Jesus College (on the Wednesday evening).

Pre-proceedings will be provided at the workshop. As with previous
workshops, revised papers and discussion transcripts will be published
by Springer-Verlag in the Lecture Notes in Computer Science series
(see LNCS 8809, 8263, 7622, 7114, 7061, 7028, 6615, 5964, 5087, 4631,
3957, 3364, 2845, 2467, 2133, 1796, 1550, 1361 and 1189 to get an idea
of the flavour).
