Security mechanisms maintaining user profile in a personal area network

A personal area network environment is a wireless ad hoc data communication system that allows a number of independent data devices to communicate. A more and more wireless devices will be used in the near future. These devices form an ad-hoc environment whose security issues are very critical. The robustness and adaptability will become the key issues to accomplish security in ad hoc wireless network. Security should be applied in all levels of the system, but main concern of this paper is to tackle this issue mainly by means of secure communication in higher layers and how it could be possible to maintain the user profile and share specific services and application with other PANs. There is a need of enhanced security via application in order to achieve seamless communication between several devices not only over the same personal area network. Some desirable properties such as authentication and privacy that can prevent the information of the users from flowing to others is considered through this application.
