Security and Privacy in the Age of Uncertainty covers issues related to security and privacy of information in a wide range of applications including: *Secure Networks and Distributed Systems; *Secure Multicast Communication and Secure Mobile Networks; *Intrusion Prevention and Detection; *Access Control Policies and Models; *Security Protocols; *Security and Control of IT in Society. This volume contains the papers selected for presentation at the 18th International Conference on Information Security (SEC2003) and at the associated workshops. The conference and workshops were sponsored by the International Federation for Information Processing (IFIP) and held in Athens, Greece in May 2003.

These proceedings contain the papers of IFIP/SEC 2010. It was a special honour and privilege to chair the Program Committee and prepare the proceedings for this conf- ence, which is the 25th in a series of well-established international conferences on security and privacy organized annually by Technical Committee 11 (TC-11) of IFIP. Moreover, in 2010 it is part of the IFIP World Computer Congress 2010 celebrating both the Golden Jubilee of IFIP (founded in 1960) and the Silver Jubilee of the SEC conference in the exciting city of Brisbane, Australia, during September 20–23. The call for papers went out with the challenging motto of “Security & Privacy Silver Linings in the Cloud” building a bridge between the long standing issues of security and privacy and the most recent developments in information and commu- cation technology. It attracted 102 submissions. All of them were evaluated on the basis of their significance, novelty, and technical quality by at least five member of the Program Committee. The Program Committee meeting was held electronically over a period of a week. Of the papers submitted, 25 were selected for presentation at the conference; the acceptance rate was therefore as low as 24. 5% making SEC 2010 a highly competitive forum. One of those 25 submissions could unfortunately not be included in the proceedings, as none of its authors registered in time to present the paper at the conference.

This book constitutes the refereed proceedings of the 26th IFIP TC 11 International Information Security Conference, SEC 2011, held in Lucerne, Switzerland, in June 2011. The 24 revised full papers presented together with a keynote talk were carefully reviewed and selected from 100 submissions. The papers are organized in topical sections on malware, information flow and DoS attacks, authentication, network security and security protocols, software security, policy compliance and obligations, privacy attacks and privacy-enhancing technologies, risk analysis and security metrics, and intrusion detection.

The NordSec workshops were started in 1996 with the aim of bringing together - searchers and practitioners within computer security in the Nordic countries – thereby establishing a forum for discussions and co-operation between universities, industry and computer societies. Since then, the workshop has developed into a fully fledged inter- tional information security conference, held in the Nordic countries on a round robin basis. The 14th Nordic Conference on Secure IT Systems was held in Oslo on 14-16 October 2009. Under the theme Identity and Privacy in the Internet Age, this year's conference explored policies, strategies and technologies for protecting identities and the growing flow of personal information passing through the Internet and mobile n- works under an increasingly serious threat picture. Among the contemporary security issues discussed were security services modeling, Petri nets, attack graphs, electronic voting schemes, anonymous payment schemes, mobile ID-protocols, SIM cards, n- work embedded systems, trust, wireless sensor networks, privacy, privacy disclosure regulations, financial cryptography, PIN verification, temporal access control, random number generators, and some more. As a pre-cursor to the conference proper, the Nordic Security Day on Wednesday 14 October hosted talks by leading representatives from industry, academia and the g- ernment sector, and a press conference was given.

The global financial crisis which erupted in 2008 had an astounding yet varied impact on the European Union (EU), with some countries benefiting from the crisis while others suffered. Today many more and varied voices articulate increasing frustration, dissatisfaction, distrust and cynicism with the current state of affairs in Europe. This book addresses the challenges and failures of the European construction today from an interdisciplinary perspective. It seeks to identify the deeper, structural causes of the failure of the European project by investigating a variety of aspects, placing Europe in a historical perspective and interpreting its trajectory in a global context. In doing so it argues that the EU, the unfinished European polity, the single European market, and the set of supranational institutions, are not sustainable in their present forms. This text will be of key interest to students and practitioners of international relations, economics, European studies, democracy and contemporary European and global challenges.

In the last two hundred years, the earth has increasingly become the private property of a few classes, races, transnational corporations, and nations. Repeated claims about the "tragedy of the commons" and the "crisis of capitalism" have done little to explain this concentration of land, encourage solution-building to solve resource depletion, or address our current socio-ecological crisis. The Commons in an Age of Uncertainty presents a new explanation, vision, and action plan based on the idea of commoning the land. The book argues that by commoning the land, rather than privatising it, we can develop the foundation for prosperity without destructive growth and address both local and global challenges. Making the land the most fundamental priority of all commons does not only give hope, it also opens the doors to a new world in which economy, environment, and society are decolonised and liberated.
