Abstract

In this talk I will present our recent results in the domain of physical layer security. The first part of the talk will focus on the security of GPS and will show some novel mechanisms that enable commercial, off the shelf receivers to detect spoofing attacks. The second part of the talk revisits the use of "friendly" jamming for achieving confidentiality in wireless communications. Here, we show that friendly jamming schemes provide weaker confidentiality guarantees than previously believed. We demonstrate this by constructing attacks that allow the attacker to recover the data in the presence of friendly jamming and by refining the conditions under which such attacks are possible.
