Wu will investigate new approaches to achieving security in wireless communications systems and other complex networks using physical layer properties. The Cross-Layer Approaches to Wireless Secure Communications (CLAWS) effort aims to address security in new communication paradigms where security is difficult to provide only through existing cryptographic and network security techniques. The CLAWS approach attempts to jointly optimize overall system performance and security. The scheme should be applicable to wireless sensor networks, wireless ad-hoc networks, and future-generation wireless and hybrid communication systems.
Addressing Physical-Layer Challenges via CLAWS: Cross-Layer Approaches to Wireless Secure Communications is a four-year, $312K grant.
