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.

As will emerge in the discussion of findings from this study, many different lines of research within the research community in the areas of Identity Management, Context-Awareness and User-Centricity have contributed to our understanding of the subject matter. This article has also addressed the issue of policy definition and usage for access control. More details on the analysis of related work and the weaknesses identified can be found in our previous work (Abdullahi, 2008, 2009) where some of the research questions are specified, an in-depth analysis of our User-Centered Identity Management (UCIM) framework is presented (Abdullahi, 2009; Abdullahi 2009).
