Secure Network Services

        Ubiquitous computing is envisioned to seamlessly integrate computing devices into our environment for the purpose of providing a wealth of information, in a real, or near real-time manner. This vision can be realized via the embedding of wireless transceivers into a large class of computing devices that are wirelessly networked in self-organized and self-maintained networks. These networks will enable a range of applications including but not limited to, home, community and enterprise networking, vehicular and transportation networks, inventory tracking, patient monitoring, environmental control, surveillance networks and tactical communications.

        The unobtrusive and robust network operation combined with constant and universal availability, emerge as key elements for successful commercialization of the aforementioned applications. In an era where the use and management of information provides a significant competitive advantage, information warfare is expected to escalate with the expansion of information availability. Provision of network services resilient to malicious adversaries that attempt to disrupt the continuous flow of valid information, while violating the privacy of the interacting parties is an area of national interest and of highest priority. However, the key properties of ubiquitous systems, that is, lack of pre-deployed infrastructure (ad hoc networks), portability and user mobility, un-tethered operation due to self-organization and self-healing processes pose, at the same time, great challenges in realizing secure networking.
