Abstract
Vehicle communication system is prone to several types of cyberattacks which may have very serious safety consequences, e.g. brakes become unworkable, steering wheel rotates in random direction, vehicle unexpectedly accelerates, dashboard indication is wrong etc. Data exchange between vehicles and base stations in vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication systems may contain information on traffic accidents, traffic jams, road constructions etc. Risks to safety as well as to data privacy in V2V and V2I systems need to be minimized. Digital signatures and HMAC can be used to provide data integrity in order to ensure protection against several types of cyberattacks such as masquerade attack, message tampering etc. We present a policy-based solution that provides controlled and privacy-preserving dissemination of data in V2V and V2I. This policy-based solution relies on Active Bundle (AB), which incorporates policy enforcement mechanism and access control policies. AB approach is applied for secure dissemination of video data in V2V and V2I systems. The usage of ABs ensures privacy of actors during disclosure of captured video in untrusted environment. Face recognition algorithm is used to identify sensitive data in videos and it is used in access control policies. We use four algorithms to process images that are captured by a vehicle's camera.

Our annual information security symposium will take place on April 3rd and 4th, 2018.
