Flexible, extensible, and efficient VANET authentication
tl;dr
We propose a new hybrid authentication mechanism, VANET authentication using signatures and TESLA++ (VAST), that combines the advantages of ECDSA signatures andTESLA. Expand

The Coremelt Attack
tl;dr
We present Coremelt, a new attack mechanism, where attackers only send traffic between each other, and not towards a victim host. Expand

Flooding-resilient broadcast authentication for VANETs
tl;dr
We propose two efficient broadcast authentication schemes, Fast Authentication (FastAuth) and Selective Authentication (SelAuth), as two countermeasures to signature flooding in Vehicular Ad-Hoc Networks. Expand

Mobile user location-specific encryption (MULE): using your office as your password
tl;dr
We use information and services available only in a trusted location to assist in key derivation without user involvement and without authenticating the laptop to any outside service. Expand

Efficient mechanisms to provide convoy member and vehicle sequence authentication in VANETs
tl;dr
Vehicular Ad hoc Networks require two new security properties: Convoy Member Authentication (CMA) and Vehicle Sequence Authentication (VSA). Expand
