Smart cars will need many more layers of cyberprotection than automakers believe is necessary, according to University College Cork's Jonathan Petit and University of California, Berkeley's Steven E. Shladover, automated automobile experts who foresee increasing problems for the vehicles once they start sharing information with each other and with the roads.
Petit and Shladover have analyzed the various means of attack, breaking them down into opposing categories: passive snooping versus active manipulation, jamming of a signal versus substitution of a false signal, and attacks on loan cars versus those on networks of cars. Some of the attacks, such as global positioning system (GPS) jamming and GPS spoofing, already are possible.
The researchers say interference with the Global Navigation Satellite System (GNSS) would be the biggest threat to a lone smart car, and believe a secure GNSS signal is mandatory.
They propose authentication systems based on encryption and misbehavior detection to protect against spoofing, which is the most serious threat to connected vehicles.
