Security and Privacy in Dynamic Environments : Proceedings of the IFIP TC-11 21st International Information Security Conference (SEC 2006)

This book contains the Proceedings of the 21st IFIP TC-11 International Information Security Conference (IFIP/SEC 2006) on Security and Privacy in Dynamic Environments held in May 2224 2006 in Karlstad, Sweden. The first IFIP/SEC conference was arranged in May 1983 in Stockholm, Sweden, one year before TC-11 was founded, with the active participation of the Swedish IT Security Community. The IFIP/SEC conferences have since then become the flagship events of TC-11.We are very pleased that we succeeded with our bid to after 23 years hold the IFIP/SEC conference again in Sweden. The IT environment now includes novel, dynamic approaches such as mobility, wearability, ubiquity, ad hoc use, mind/body orientation, and business/market orientation. This modern environment challenges the whole information security research community to focus on interdisciplinary and holistic approaches whilst retaining the benefit of previous research efforts. Papers offering research contributions focusing on dynamic environments in addition to other aspects of computer security and privacy were solicited for submission to IFIP/SEC 2006. We received 141 submissions which were all reviewed by at least three members of the international program committee. At a one-day program committee meeting, the submitted papers were discussed, and 35 papers were selected for presentation at the conference, which means an acceptance rate of 24.8%. A special emphasis of IFIP/SEC 2006 is on Privacy and Privacy Enhancing Technologies, which is addressed by 9 of the 35 accepted papers. Further topics addressed include security in mobile and ad hoc networks, access control for dynamic environments, new forms of attacks, security awareness, intrusion detection and network forensics.These Proceedings also include the papers of the following two workshops that are associated with SEC 2006: the workshop on Security Culture organized by IFIP Working Group 11.1/11.8 as well as the I-NetSec06 workshop on Privacy and Anonymity Issues in Networked and Distributed Systems organized by IFIP Working Group 11.4. Both workshops were organized autonomously by the respective IFIP Working Groups. They had their own call for papers, program committees, and selection processes with acceptance rates of papers similar to the one of the main IFIP/SEC 2006 conference.IFIP/SEC 2006 is organized in cooperation with Karlstad University, SIG Security, and Dataforeningen i Sverige. We would like to thank Microsoft AB, Karlstads kommun, SAAB AB, and TietoEnator, who are sponsoring IFIP/SEC 2006. Furthermore, we gratefully thank all authors, members of the program committees, and additional reviewers for their contributions to the scientific quality of this conference and the two workshops. Last but not least, we owe thanks to the organizing committee, and especially to its chair Dr. Albin Zuccato, for all the efforts and dedication in preparing this conference
