Proposal Title: CT-ISG: Collaborative Research: Key Generation from PhysicalLayer Characteristics in Wireless NetworksInstitution: University of ConnecticutAbstract Date: 08/05/08This project focuses on the development of a new class of secret key generation andrenewal algorithms for securing wireless networks by taking advantage of physicallayer characteristics. The basis of the approach is the identification of measurablequantities of the wireless channel between a pair of nodes that are highly correlatedexclusively between them (albeit not identical). Capitalizing on this correlation, theproject develops algorithms for obtaining a shared key under various adversarialmodels.This addresses a critical problem area as the broadcast nature of a wireless linkprovides a natural eavesdropping and intervention capability to an adversary and thus itfollows that securing a wireless link is essential to the security of any wireless network.This project undertakes the design, implementation, analysis and testing of severalprotocols and clarifies the relationship between the channel characteristics and thecryptographic protocols that use them. It also investigates the trade-offs betweencomputational and communication costs, and quantifies the level of security achievedby the key generation and renewal protocols assuming various adversarial models.The broader impact of the project is in the potential of making wireless communicationsmore secure while avoiding costs (both computational and organizational) ofcryptography. Given the increased wireless internetworking and the multitude ofwireless enabled devices presently carried by an average user, the security of thewireless link becomes one of the most critical aspects of securing computer systems.The reduction in the computation also will translate to a reduction in energy use,important to battery or alternative powered systems. Educationally, the project willpresent an attractive combination of aspects of signal processing, computer security,algorithms and cryptography and will offer a wealth of problems for student engagement
