2. 1. On Securing Vehicular Communications: Methods and Recommendations for Secure In-vehicle and Car2X Communications

   Author : Nasser Nowdehi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; V2X; in-vehicle network; vehicular communication; security; ETSI;

   Abstract : Today's vehicles contain approximately more than 100 interconnected computers (ECUs), several of which will be connected to the Internet or external devices and networks around the vehicle. In the near future vehicles will extensively communicate with their environment via Vehicle to Vehicle and Vehicle to Infrastructure (together called V2X) communications. READ MORE
