Some attacks against vehicles' passive entry security systems and their solutions

Recently, several companies have introduced passive entry systems for automotive applications. These systems are intended to increase user comfort by eliminating the requirement that the user has to reach for the customer identification device (CID), a credit card like tool, to gain access to the vehicle compartment. While this extra level of comfort is a desirable feature, especially in luxury vehicles, it introduces several key attacks against the system. This paper describes several techniques of potential attacks against the passive entry system and proposes solutions to protect the vehicle from such attacks.     

Enhancing Security and Privacy in Traffic-Monitoring Systems

Intelligent transportation systems increasingly depend on probe vehicles to monitor traffic: they can automatically report position, travel time, traffic incidents, and road surface problems to a telematics service provider. This kind of traffic-monitoring system could provide good coverage and timely information on many more roadways than is possible with a fixed infrastructure such as cameras and loop detectors. This approach also promises significant reductions in infrastructure cost because the system can exploit the sensing, computing, and communications devices already installed in many modern vehicles. This architecture separates data from identities by splitting communication from data analysis. Data suppression techniques can help prevent data mining algorithms from reconstructing private information from anonymous database samples     

Analysis of attacks against the security of keyless-entry systems for vehicles and suggestions for improved designs

Remote control of vehicle functions using a handheld electronic device became a popular feature for vehicles. Such functions include, but are not limited to, locking, unlocking, remote start, window closures, and activation of an alarm. As consumers enjoy the remote access and become more comfortable with the remote functions, original equipment manufacturers (OEMs) have started looking for new features to simplify and reduce the user interface for vehicle access. These new features will provide users with an additional level of comfort without requiring them to touch or press any button on any remote devices to gain access to the vehicle. While this extra level of comfort is a desirable feature, it introduces several security threats against the vehicle's keyless-entry system. This paper describes a number of attacks against the security of keyless-entry systems of vehicles and also presents analyzes of several attacks and compares the vulnerability of the system under different attacks. At the end, some suggestions for improved design are proposed.
