The CAN Sentinel resides on the bus, monitoring transactions with a vehicle’s electronic control units (ECUs), identifying suspicious activity, preventing malicious messages and silencing attacks.
Approaches to secure the CAN have so far focused on stopping cyber-intrusions from the outside (software patches or APIs, securing Wi-Fi devices), rather than embedding security into the bus itself.
This has left the CAN bus and the vehicle open to all sorts of potential attack from frame-spoofing hacks.
The specific advantage of hardware-based security, UltraSoC’s marketing director Andy Gothard told EW, is that it can respond in a single cycle, reducing the response-time to microseconds, as opposed to milliseconds in a software-based alternative.
CAN Sentinel is configurable with user-defined security rules, providing protection against exploits such as frame spoofing, and allowing the system to be modified in the future to respond to security requirements.
It also integrates with the company’s embedded analytics and monitoring modules.
“The CAN (controller area network) bus has become ubiquitous in the automotive industry. More recently it has also become recognized as possibly the most serious security vulnerability in cars,” the firm says.
A number of attacks – for example the Miller-Valasek Jeep hack – have exploited its lack of security features.
Gajinder Panesar, CTO at UltraSoC, added: “Our products provide intelligent analytics which are capable of learning and evolving to tackle a rapidly changing threat landscape.”
The CAN Sentinel follows the firm’s recently launched Bus Sentinel, its first venture into cybersecurity.
This was launched in late 2019 to simplify the embedding of a secure monitoring architecture into the heart of mission-critical and safety-critical devi ..
