Title: “Know your neighbor,” “Keep your distance,” and other cautionary tales for wireless systems

Abstract: Wireless devices are becoming pervasive and increasingly versatile. Untethered communication enables a multitude of applications closely knitted with the physical world, with the devices often being the network: anytime and anywhere communication, location-aware services, environmental monitoring, intelligent transportation, socially motivated information exchange. Wireless systems are, however, a double-edged sword: their applications and the nature of wireless communications create new vulnerabilities, and attacks against wireless systems can create new dangers for their users.

This seminar will focus on the unique characteristics and security requirements of wireless systems. Recent results on two characteristic problems, secure neighbor discovery (SND) and secure ranging/distance bounding (SR/DB), are distilled. The first part of the talk will discuss how to build SND, a fundamental building block for secure multi-hop communication. The second part of the talk will cover DB and show how to mount attacks against mainstream ranging technologies.
