Summary : The new 802.11p standard aims to provide reliable wireless communication for vehicular environments. The P802.11p specification defines functions and services required by Wireless Access in Vehicular Environments (WAVE) conformant stations to operate in varying environments and exchange messages either without having to join a BSS or within a BSS, and defines the WAVE signaling technique and interface functions that are controlled by the 802.11 MAC.
Wireless telecommunications and information exchange between roadside and vehicle systems present some interesting security implications. This talk will present an analysis of the 802.11p 5.9 GHz band Wireless Access in Vehicular Environments (WAVE) / Dedicated Short Range Communications (DSRC), Medium Access Control (MAC), and Physical Layer (PHY) Specifications of this protocol. We will present methods of analyzing network communications (GNU Radio/USRP, firmware modifications, etc.), and potential security issues in the implementation of the protocol in practical environments such as in toll road implementations, telematics systems, and other implementations.
