The emergence of smart environments where computing devices are embedded pervasively in the physical world has made possible many interesting applications and triggered several new research areas. Mobile ad hoc networks (MANETs), sensor networks, and RFID systems are all examples of such pervasive systems, operating with constrained resources, that intelligently configure and connect themselves. Operating on an open medium and lacking fixed infrastructure, such networks suffer from critical security vulnerabilities, for which few satisfactory solutions currently exist, particularly with respect to availability and denial-ofservice attacks. In addition, much of the extant knowledge in network security and cryptography cannot be readily transfered to the newer settings, which involve weaker devices, and less structured and less redundant networks. For these reasons, traditional security approaches, in particular regarding provision of availability, are often inappropriate for the context of ubiquitous computing.

In this project we investigate the security of pervasive systems with focus on availability issues in the presence of Byzantine faults. Our goal is to formulate rigorous simulation frameworks for analyzing security objectives; and more importantly to design novel mechanisms and algorithms that achieve proven availability, uninterrupted services, high efficiency, and low overhead in such systems. Whenever possible, we favor approaches that integrate security into existing protocols that are well established in the literature. Our focus will be on securing MANET and RFID applications.
