Available in PDF, EPUB and Kindle. Book excerpt: Contextual information and Identity Management (IM) is of paramount importance in the growing use of portable mobile devices for sharing information and communication between emergency services in pervasive ad-hoc environments. Mobile Ad-hoc Networks (MANets) play a vital role within such a context. The concept of ubiquitous/pervasive computing is intrinsically tied to wireless communications. Apart from many remote services, proximity services (context-awareness) are also widely available, and people rely on numerous identities to access these services. The inconvenience of these identities creates significant security vulnerability as well as user discomfort, especially from the network and device point of view in MANet environments. In this article, the authors address how contextual information is represented to facilitate IM and present a User-centered and Context-aware Identity Management (UCIM) framework for MANets.

Mobile Ad-hoc Networks (MANets) play a vital role within such a context. The concept of ubiquitous/pervasive computing is intrinsically tied to wireless communications. Apart from many remote services, proximity services (context-awareness) are also widely available, and people rely on numerous identities to access these services. The inconvenience of these identities creates significant security vulnerability as well as user discomfort, especially from the network and device point of view in MANet environments. The need of displaying only relevant contextual information (CI) with explicit user control arises in energy constraint devices and in dynamic situations. We propose an approach that allows users to define policies dynamically and a ContextRank Algorithm which will detect the usability of CI. The proposed approach is not only efficient in computation but also gives users total control and makes policy specification more expressive. In this Chapter, the authors address the issue of dynamic policy specification, usage of contextual information to facilitate IM and present a User-centered and Context-aware Identity Management (UCIM) framework for MANets.

This book was released on 2013-12-12 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The area of MANets (Mobile Ad-hoc Networks) is still in its infancy in the research community, but it plays a vital role surrounded by the growing trend of mobile technology for business as well as private and governmental uses. The concept of ubiquitous/pervasive computing is almost intrinsically tied to wireless communications. Emerging next-generation wireless networks enable innovative service access in every situation. Apart from many remote services, proximity services (context-awareness) will also be widely available. People currently rely on numerous forms of identities to access these services. The inconvenience of possessing and using these identities creates significant security vulnerability, especially from network and device point of view in MANet environments. The emergent notion of ubiquitous computing also makes it possible for mobile devices to communicate and provide services via networks connected in an ad-hoc manner. Digital identities are at the heart of many contemporary strategic innovations for crime prevention and detection, internal and external security, business models etc. This requires disclosing personal information and the applicability of contextual information as well as allowing users to be in control of their identities. In this paper we discuss the requirements for the development of an innovative, easy-to-use identity management mechanism within MANet environments. We convey various possibilities, challenges, and research questions evolving in these areas. The issues of context-awareness, making use of partial identities as a way of user identity protection, and providing a better way for node identification are addressed. We also examine the area of user-centricity for MANets together with its security issues and implications. We propose a framework for MANets that makes the flow of partial identities explicit, gives users control over such identities based on the respective situation and context, and creates a balance between convenience and privacy.
Download or read book Identity Management for Internet of Things written by Parikshit N. Mahalle and published by CRC Press. This book was released on 2022-09-01 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-05-03 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in context-aware computing has produced a number of middleware systems for context management. However, development of ubiquitous context-aware applications is still a challenge because most current middleware systems are still focused on isolated and static context-aware environments. Context-aware environments are inherently dynamic as a result of occasional additions or upgrade of sensors, applications or context inference mechanisms. Context Management for Distributed and Dynamic Context-Aware Computing proposes a novel architecture for context management based on the concept of context domains, allowing applications to keep context interests across distributed context management systems. The authors describe a distributed middleware that implements the aforementioned concepts, without compromising scalability and efficiency of context access.
Download or read book Ambient Intelligence written by Giuseppe Riva and published by IOS Press. This book was released on 2005 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The metaphor of Ambient Intelligence (AmI) tries to picture a vision of the future where all of us will be surrounded by 'intelligent' electronic environments, and this ambient has claims to being sensitive and responsive to our needs. Ambient Intelligence without invasion of privacy represents a long-term vision for the EU Information Society Technologies Research programme. A strong multi-disciplinary and collaborative approach is a key requirement for large-scale technology innovation and the development of effective applications. Up to now, most of the books and papers related to AmI focus their analysis on the technology potential only. An important feature of this volume is the link between the technology - through the concepts of ubiquitous computing and intelligent interface - and the human experience of interacting in the world - through a neuro-psychological vision centred on the concept of 'presence'. Presence - the sense of being there - is the experience of projecting one's mind through media to other places, people and designed environments. The combination of recent discoveries in cognitive neuroscience - which make it possible to acquire a better understanding of the human aspects of presence, and the breakthroughs at the level of the enabling technologies make it increasingly possible to build novel systems based on this understanding. The goal of this volume is to assess the technologies and processes that are behind the AmI vision, in order to help the development of state-of-the-art applications. More in detail, this volume aims at supporting researchers and scientists, interested in the understanding and exploiting the potential of AmI.
