This volume contains the proceedings of IFIPTM 2010, the 4th IFIP WG 11.11 International Conference on Trust Management, held in Morioka, Iwate, Japan during June 16-18, 2010. IFIPTM 2010 provided a truly global platform for the reporting of research, development, policy, and practice in the interdependent arrears of privacy, se- rity, and trust. Building on the traditions inherited from the highly succe- ful iTrust conference series, the IFIPTM 2007 conference in Moncton, New Brunswick, Canada, the IFIPTM 2008 conference in Trondheim, Norway, and the IFIPTM 2009 conference at Purdue University in Indiana, USA, IFIPTM 2010 focused on trust, privacy and security from multidisciplinary persp- tives. The conference is an arena for discussion on relevant problems from both research and practice in the areas of academia, business, and government. IFIPTM 2010 was an open IFIP conference. The program of the conference featured both theoretical research papers and reports of real-world case studies. IFIPTM 2010 received 61 submissions from 25 di?erent countries: Japan (10), UK (6), USA (6), Canada (5), Germany (5), China (3), Denmark (2), India (2), Italy (2), Luxembourg (2), The Netherlands (2), Switzerland (2), Taiwan (2), Austria, Estonia, Finland, France, Ireland, Israel, Korea, Malaysia, Norway, Singapore, Spain, Turkey. The Program Committee selected 18 full papers for presentation and inclusion in the proceedings. In addition, the program and the proceedings include two invited papers by academic experts in the ?elds of trust management, privacy and security, namely, Toshio Yamagishi and Pamela Briggs

This book constitutes the refereed proceedings of the 36th IFIP TC 11 International Conference on Information Security and Privacy Protection, SEC 2021, held in Oslo, Norway, in June 2021.*The 28 full papers presented were carefully reviewed and selected from 112 submissions. The papers present novel research on theoretical and practical aspects of security and privacy protection in ICT systems. They are organized in topical sections on digital signatures; vulnerability management; covert channels and cryptography; application and system security; privacy; network security; machine learning for security; and security management. *The conference was held virtually.

This is the first comprehensive treatment of subjective logic and all its operations. The author developed the approach, and in this book he first explains subjective opinions, opinion representation, and decision-making under vagueness and uncertainty, and he then offers a full definition of subjective logic, harmonising the key notations and formalisms, concluding with chapters on trust networks and subjective Bayesian networks, which when combined form general subjective networks. The author shows how real-world situations can be realistically modelled with regard to how situations are perceived, with conclusions that more correctly reflect the ignorance and uncertainties that result from partially uncertain input arguments. The book will help researchers and practitioners to advance, improve and apply subjective logic to build powerful artificial reasoning models and tools for solving real-world problems. A good grounding in discrete mathematics is a prerequisite.

This book constitutes the refereed proceedings of the 17th Nordic Conference on Secure IT Systems, NordSec 2012, held in Karlskrona, Sweden, in October 2012. The 16 revised papers were carefully reviewed and selected from 32 submissions. The papers are organized in topical sections on application security, security management, system security, network security, and trust management.

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.

This book constitutes the thoroughly refereed post-conference proceedings of the 8th International Workshop on Security and Trust Management, STM 2012, held in Pisa, Italy, in September 2012 - in conjunction with the 17th European Symposium Research in Computer Security (ESORICS 2012). The 20 revised full papers were carefully reviewed and selected from 57 submissions. The papers are organized into topical sections on policy enforcement and monitoring; access control; trust, reputation, and privacy; distributed systems and physical security; authentication and security policies.
