User Centred And Context Aware Identity Management In Mobile Ad Hoc Networks

The emergent notion of ubiquitous computing makes it possible for mobile devices to communicate and provide services via networks connected in an ad-hoc manner. These have resulted in the proliferation of wireless technologies such as Mobile Ad-hoc Networks (MANets), which offer attractive solutions for services that need flexible setup as well as dynamic and low cost wireless connectivity. However, the growing trend outlined above also raises serious concerns over Identity Management (IM) due to a dramatic increase in identity theft. The problem is even greater in service-oriented architectures, where partial identities are sprinkled across many services and users have no control over such identities. This book provides a review of some issues of contextual computing, its implications and usage within pervasive environments. The book will also introduce the concept of Security of Systems-of-Systems (SoS) Composition and its security implications within the domain of ubiquitous computing and Crisis Management in large scale disaster recovery situations and scenarios. To tackle the above problems, the book will emphasise the fact that it is essential to allow users to have full control over their own identities in MANet environments. So far, the development of such identity control remains a significant challenge for the research community. The main focus of this book is on the area of identity management in MANets and emergency situations by using context-awareness and user-centricity together with its security issues and implications. Context-awareness allows us to make use of partial identities as a way of user identity protection and node identification. User-centricity is aimed at putting users in control of their partial identities, policies and rules for privacy protection. These principles help us to propose an innovative, easy-to-use identity management framework for MANets. The framework makes the flow of partial identities explicit; gives users control over such identities based on their respective situations and contexts, and creates a balance between convenience and privacy. The book presents our proposed framework, its development and lab results/evaluations, and outlines possible future work to improve the framework. This book will be of great interest and benefit to undergraduate students undertaking computer science modules on security and ubiquitous computing and postgraduate students studying the security of large scale systems of systems composition, as well as those doing their projects in those areas. The book will also accommodate the needs of early researchers and DPhil/PhD or MPhil students exploring the concept of security in ubiquitous environments, while additionally being of great interest to lecturers teaching related modules and industrial researchers.

The Annual (ICGS) International Conference is an established platform in which se- rity, safety and sustainability issues can be examined from several global perspectives through dialogue between academics, students, government representatives, chief executives, security professionals, and research scientists from the United Kingdom and from around the globe. The 2009 two-day conference focused on the challenges of complexity, rapid pace of change and risk/opportunity issues associated with modern products, systems, s- cial events and infrastructures. The importance of adopting systematic and systemic approaches to the assurance of these systems was emphasized within a special stream focused on strategic frameworks, architectures and human factors. The conference provided an opportunity for systems scientists, assurance researchers, owners, ope- tors and maintainers of large, complex and advanced systems and infrastructures to update their knowledge with the state of best practice in these challenging domains while networking with the leading researchers and solution providers. ICGS3 2009 received paper submissions from more than 20 different countries around the world. Only 28 papers were selected and were presented as full papers. The program also included three keynote lectures by leading researchers, security professionals and government representatives. June 2009 Hamid Jahankhani Ali Hessami Feng Hsu

With the advancements of semantic web, ontology has become the crucial mechanism for representing concepts in various domains.

This book constitutes the refereed proceedings of two workshops held in conjunction with the 8th FIRA International Conference on Secure and Trust Computing, Data Management, and Applications, STA 2011, in Crete, Greece, in June 2011. STA 2011 is the first conference after the merger of the successful SSDU, UbiSec, and TRUST symposium series previously held from 2006 until 2010 in various locations. The 14 full papers of the IWCS 2011 and 10 papers of the STAVE 2011 workshop were carefully reviewed and individually selected from the lectures given at each workshop. The International Workshop on Convergence Security in Pervasive Environments, IWCS 2011, addresses the various theories and practical applications of convergence security in pervasive environments. The International Workshop on Security & Trust for Applications in Virtualized Environments, STAVE 2011, shows how current virtualization increases the sharing of compute, network and I/O resources with multiple users and applications in order to drive higher utilization rates, what replaces the traditional physical isolation boundaries with virtual ones.

This work represents a milestone for the "ULOOP User-centric Wireless Local Loop" project funded by the EU IST Seventh Framework Programme. ULOOP is focused on the robust, secure, and autonomic deployment of user-centric wireless networks. Contributions by ULOOP partners as well as invited tutorials by international experts in the field. The expected impact is to increase awareness to user-centric networking in terms, e.g., of business opportunities and quality of experience, and to present adequate technology to sustain the growth of user-friendly wireless architectures. Throughout the last 3 years, ULOOP has developed enabling technologies for user-centricity in wireless networks, with particular emphasis on social trust management, cooperation incentives, community building, mobility estimation, and resource management. This work will be of interest to researchers, policymakers, operators, vendors, and end-users interested in the current and future directions of user-centric access networks.

The Internet of Things is a wide-reaching network of devices, and these devices can intercommunicate and collaborate with each other to produce variety of services at any time, any place, and in any way. Maintaining access control, authentication and managing the identity of devices while they interact with other devices, services and people is an important challenge for identity management. The identity management presents significant challenges in the current Internet communication. These challenges are exacerbated in the internet of things by the unbound number of devices and expected limitations in constrained resources. Current identity management solutions are mainly concerned with identities that are used by end users, and services to identify themselves in the networked world. However, these identity management solutions are designed by considering that significant resources are available and applicability of these identity management solutions to the resource constrained internet of things needs a thorough analysis. Technical topics discussed in the book include:• Internet of Things;• Identity Management;• Identity models in Internet of Things;• Identity management and trust in the Internet of Things context;• Authentication and access control;Identitymanagement for Internet of Things contributes to the area of identity management for ubiquitous devices in the Internet of Things. It initially presents the motivational factors together with the identity management problems in the context of Internet of Things and proposes an identity management framework. Following this, it refers to the major challenges for Identitymanagement and presents different identity management models. This book also presents relationship between identity and trust, different approaches for trust management, authentication and access control.
