This book constitutes the thoroughly refereed post-proceedings of the 10th International Workshop on Security Protocols, held in Cambridge, UK, in April 2002.The 16 revised full papers presented together with transcriptions of the discussions following the presentations have passed through two rounds of reviewing, revision, and selection. Also included are abstracts and summaries of an introduction and a keynote, as well as a concluding discussion and statement. Among the topics addressed are authentication, mobile ad-hoc network security, secure distributed document processing, access control, confidentiality, protocol attacks, delegation, certified transfer servers, intrusion tolerance, multi-party communication protocols, IPv6 security, and others.

Greetings. These are the proceedings of the 11th in our series of International Workshops on Security Protocols. Our theme this time was “Where have all the Protocols gone?” Once upon a time security protocols lived mainly in the network and transport layers. Now they increasingly hide in applications, or in specialised hardware. Does this trend lead to better security architectures, or is it an indication that we are addressing the wrong problems? The intention of the workshops is to provide a forum where incompletely workedoutideascanstimulatediscussion,openupnewlinesofinvestigation,and suggestmoreproblems. The positionpaperspublished herehavebeen revisedby the authors in the light of their participation in the workshop. In addition, we publish edited transcripts of some of the discussions, to give our readers access to some of the roads ahead not (yet) taken. We hope that these revised position papers and edited transcripts will give you at least one interesting idea of your own to explore. Please do write and tell us what it was. Our purpose in publishing these proceedings is to produce a conceptual map which will be of enduring interest, rather than to be merely topical. This is perhaps just as well, given the delay in production. This year we moved to new computer-based recording technology, and of course it failed completely.

Here are the proceedings of the 12th International Workshop on Security P- tocols. We hope that you will enjoy them, and that they will cause you to think at least one heretical thought. Please write or e-mail and share it with us. Our theme this workshop was “Authentic Privacy.” Traditionally we have based authentication upon a rather strong notion of identity, and have then built other security services on top of authentication. Perhaps if we want a more nuanced notion of privacy, then we need to re-examine some of our assu- tions, particularly when attackers and defenders share the same resources and infrastructure. The position papers published here have been revised by the participants in the workshop, and are followed by edited (heavily in some cases) transcripts of parts of the discussions which they led. Our thanks to Sidney Sussex CollegeCambridgefor the use of their facilities, to Johanna Hunt at the University of Hertfordshire for organizing the logistics of the workshop and orchestrating the production of these proceedings, to Lori KlimaszewskaoftheUniversityofCambridgeComputingServicefortranscribing the audio tapes (in which “viruses without halos” could have caused havoc but didn’t), and to Donald Hunt for impeccable copyediting. Finally, it is both a sadness and a pleasure to pay our tribute to David Wheeler,oneoftheoriginalforty-ninersattheCambridgeComputerLaboratory and author of the initial orders for EDSAC. The second version of initial orders is the Platonic bootstrap.

This book constitutes the thoroughly refereed post-proceedings of the 8th International Workshop on Security Protocols held in Cambridge, UK in April 2000. The 21 papers presented with transcriptions of the discussion following the presentation have gone through two rounds of revision and selection; also included are a keynote address and a discussion summary and an afterword by the volume editors. Among the topics addressed are authentication, trust in cyberspace, identification protocols, administration and government issues, specification, access privileges, PKI certificates, trust-based billing systems, public-key cryptosystems, denial of service, anonymous auction protocols, and certification.

This book constitutes the thoroughly refereed post-proceedings of the 9th International Workshop on Security Protocols held in Cambridge, UK in April 2001. The 13 revised full papers presented together with transcriptions of the discussions following the presentations have gone through two rounds of reviewing, revision, and selection. Also included are abstracts and transcriptions of invited presentations and topically focused discussions. Among the topics addressed are mobile computing and security, denial of service, authentication, Internet protocols, timing attacks, PIM security, security engineering, non-repudiation, trust management, access control policies, and Bluetooth security.

This book constitutes the thoroughly refereed post-workshop proceedings of the 7th International Workshop on Security Protocols held in Cambridge, UK, in April 1999.The 20 revised contributions presented as position statements are followed by transcripts of the discussions between the authors and the audience; thus the volume reflects the lively interaction at the workshop. All relevant aspects of current research and development in the area are addressed.

Welcome back to the International Security Protocols Workshop. Our theme for this, the 14th workshop in the series, is “Putting the Human Back in the Protocol”. We’ve got into the habit of saying “Of course, Alice and Bob aren’t really people. Alice and Bob are actually programs running in some computers.” But we build computer systems in order to enable people to interact in accordance with certain social protocols. So if we’re serious about system services being end-to-end then, at some level of abstraction, the end points Alice and Bob are humanafterall.Thishascertainconsequences.Weexploresomeoftheminthese proceedings, in the hope that this will encourage you to pursue them further. Is Alice talking to the correct stranger? Our thanks to Sidney Sussex College, Cambridge for the use of their faci- ties, and to the University of Hertfordshire for lending us several of their sta?. Particular thanks once again to Lori Klimaszewska of the University of C- bridge Computing Service for transcribing the audio tapes, and to Virgil Gligor for acting as our advisor.

This book constitutes the thoroughly refereed post-proceedings of the 15th International Workshop on Security Protocols, held in Brno, Czech Republic, in April 2007.The 15 revised full papers presented together with edited transcriptions of some of the discussions following the presentations have passed through multiple rounds of reviewing, revision, and selection. The topics addressed reflect the question "When is a Protocol Broken?" and how can it degrade gracefully in the face of partially broken assumptions, or how can it work under un(der)specified assumptions.
