Fujitsu develops technology to detect cyberattacks on in-vehicle networks; eliminating false positives
05 February 2018
Fujitsu Limited and Fujitsu Laboratories have developed technology to detect cyberattacks on in-vehicle networks. Existing, generally available technology detects attack messages by checking if the interval between messages periodically transmitted through the in-vehicle network is within accepted boundaries. However, because the timing with which a genuine message is received can vary, genuine messages can be misidentified as attack messages, which has the potential to interrupt smooth travel as a result.
With this newly developed technology, the system learns the cycles of message reception under normal conditions, and then uses the difference between the learned number of messages received and the actual number of messages received to determine whether an attack message is being received.
Because this system uses the subsequent timing of message receipt to supplement the detection results when there is a difference, it can detect attack messages while eliminating false positives.
Fujitsu aims to commercialize this technology in fiscal 2018 as a component of the Mobility IoT Platform offered by Fujitsu Limited.
