The development of electronic commerce and other applications on the Internet is held up by concerns about security. Cryptography—the science of codes and ciphers—will be a significant part of the solution, but one of the hardest problems is enabling users to find out which cryptographic key belongs to whom. The main things that can go wrong with cryptography are similar to those that can go wrong with a signature stamp. A stamp can be stolen or counterfeit; or it may not belong to the person one thought it did. The first two risks can be controlled largely by technical measures. The third risk is the hard one, and the one that this book helps to solve. Many people who use cryptographic services on the Internet have had their keys certified by one or more of about a thousand important keys. The pioneers of cryptography hoped that these keys would in turn be certified by the United Nations or by each other, or listed in the phone book. For a variety of political and competitive reasons, this has not happened. The result is chaos, and the situation is bound to get worse as both companies and governments try to stake out claims in cyberspace. The primary aim of this book is to cut through the chaos by publishing the thousand or so important keys in paper form, as a kind of global phone book. The secondary aim is political: By printing these keys on paper, we can use established legal protections to limit government interference.

This book constitutes the thoroughly refereed post-workshop proceedings of the 6th International Workshop on Security Protocols held in Cambridge, UK in April 1998. The 15 revised papers presented as position statements are followed by transcripts of the discussions between the authors and the audience. Also included is a report on the final panel discussion on future directions in security protocols research and developments. Thus the volume reflects the lively interaction at the workshop. The papers are devoted to the interrelations between trust and delegation, exploring the implications and effects of these upon such issues as authorization, security policy, and cryptosystems and component design.

Security Protocols

James A. Malcolm

Another year, another workshop. Here are the proceedings of the seventh Cambridge International Workshop on Security Protocols. All very well, you may think, but can there really still be anything genuinely new to say? Is it not just the same old things a tiny bit better? Well, perhaps surprisingly, this year we discoveredsome radically new things beginning to happen. The reasons in retrospect are not far to seek: advances in technology, changes in the system context, and new types of consumer devices and applications have combined to expose new security requirements. This has led not only to new protocols and models, but also to known protocols being deployedindelicate newways,withpreviousfragilitiesofwatermarkingand- tual authentication, for example, becoming desirable features. At the workshop we identi?ed several of these developments and began to map out some lines of enquiry. This volume brings you a selection of deliberately disputatious position - pers, followed by not-quite-verbatim transcripts of the discussions which they provoked. As always, our purpose in making these proceedings available to you is the hope that they will move your thinking in an unexpected direction. If you ?nd your attention caught by something here, if it makes you pause to re?ect, or to think “why, that is justso wrong”,then good. We’re waiting for your mail.

This book constitutes the thoroughly refereed post-proceedings of the 14th International Workshop on Security Protocols, held in Cambridge, UK, in March 2006. The 21 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. Among the topics addressed are authentication, anonymity, cryptographics and biometrics, cryptographic protocols, network security, privacy, SPKI, user-friendliness, access control, API security, costs of security, and others.

This book constitutes the thoroughly refereed post-conference proceedings of the 7th IFIP WG 9.2, 9.6/11.7, 11.4, 11.6 International Summer School, held in Trento, Italy, in September 2011. The 20 revised papers were carefully selected from numerous submissions during two rounds of reviewing. The book also contains two invited talks. The papers are organized in topical sections on privacy metrics and comparison, policies, privacy transparency in the age of cloud computing, privacy for mobile applications, consumer privacy, privacy for online communities, privacy for eHealth and eID applications, privacy attacks and problems, and ethics.
