Privacy and Security in an Age of Surveillance (Dagstuhl Perspectives Workshop 14401)

Abstract
Before the Snowden revelations about the scope of surveillance by the NSA and its partner agencies, most people assumed that surveillance was limited to what is necessary and proportionate for these agencies to fulfil their prescribed role. People assumed that oversight mechanisms were in place to ensure that surveillance was appropriately constrained. But the Snowden revelations undermine these beliefs. We now know that nations are amassing personal data about people's lives at an unprecedented scale, far beyond most people's wildest expectations. The scope of state surveillance must be limited by an understanding of its costs as well as benefits. The costs are not limited to financial ones but also include eroding personal rights and the degradation to the integrity, vibrancy, or fundamental character of civil society. This manifesto stems from a Dagstuhl Perspectives Workshop held in late 2014. The meeting was a four-day gathering of experts from multiple disciplines connected with privacy and security. The aim was to explore how society as a whole, and the computing science community in particular, should respond to the Snowden revelations. More precisely, the meeting discussed the scope and nature of the practice of mass-surveillance, basic principles that should underlie reforms, and the potential for technical, legal, and other means to help stem or restore human rights threatened by ubiquitous electronic surveillance.

Privacy and Security in an Age of Surveillance (Dagstuhl Perspectives Workshop 14401)

Authors: Bart Preneel, Phillip Rogaway, Mark D. Ryan, and Peter Y. A. Ryan

Published in: Dagstuhl Reports, Volume 4, Issue 9 (2015)

Abstract
The Snowden revelations have demonstrated that the US and other nations are amassing data about people's lives at an unprecedented scale. Furthermore, these revelations have shown that intelligence agencies are not only pursuing passive surveillance over the world's communication systems, but are also seeking to facilitate such surveillance by undermining the security of the internet and communications technologies. Thus the activities of these agencies threatens not only the rights of individual citizens but also the fabric of democratic society. Intelligence services do have a useful role to play in protecting society and for this need the capabilities and authority to perform targeted surveillance. But the scope of such surveillance must be strictly limited by an understanding of its costs as well as benefits, and it should not impinge on the privacy rights of citizens any more than necessary. Here we report on a recent Dagstuhl Perspectives Workshop addressing these issues - a four-day gathering of experts from multiple disciplines connected with privacy and security. The meeting explored the scope of mass-surveillance and the deliberate undermining of the security of the internet, defined basic principles that should underlie needed reforms, and discussed the potential for technical, legal and regulatory means to help restore the security of the internet and stem infringement of human-rights by ubiquitous electronic surveillance.

07421 Abstracts Collection – Formal Protocol Verification Applied

Authors: Liqun Chen, Steve Kremer, and Mark D. Ryan

Published in: Dagstuhl Seminar Proceedings, Volume 7421, Formal Protocol Verification Applied (2008)

Abstract
From 14/10/2007 to 19/10/2007, the Dagstuhl Seminar 07421 ``Formal Protocol Verification Applied'' was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

07421 Executive Summary – Formal Protocol Verification Applied

Authors: Liqun Chen, Steve Kremer, and Mark D. Ryan

Published in: Dagstuhl Seminar Proceedings, Volume 7421, Formal Protocol Verification Applied (2008)

Abstract
Security protocols are a core part of distributed computing systems, and are part of our everyday life since they are used in web servers, email, mobile phones, bank transactions, etc. However, security protocols are notoriously difficult to get right. There are many cases of protocols which are proposed and considered secure for many years, but later found to have security flaws. Formal methods offer a promising way for automated security analysis of protocols. While there have been considerable advances in this area, most techniques have only been applied to academic case studies and security properties such as secrecy and authentication. The seminar brought together researchers deploying security protocols in new application areas, cryptographers, and researchers from formal methods who analyse security protocols. The interaction between researchers from these different communities aims to open new research topics, e.g., identify new security properties that need verification and refine abstractions of the abstract models of crytpographic primitives.
