SeCurity ProtoColS By SCieNtiStS outfitted witH gPS aNd BluetootH to ProteCt Smart CarS

Scientists have created a security protocol to protect smart cars — equipped with GPS, bluetooth and internet connections — from being hacked. The security protocol protects CAN in two ways. First, it authenticates messages sent through the network by creating an authentication code. This code allows nodes on the network to differentiate between a valid message and an attacker’s message. The second feature protects against replay attacks, when a hacker attempts to breach the network by repeatedly sending messages. The protocol uses a timestamp to calculate when the network last received message.
