The automotive electronics manufacturer, Harman, says it is working with a number of vehicle makers to protect connected cars from hacking.
As more and more car makers release new models that can connect to the internet, car makers are being pushed to ensure its security keeps pace.
Asaf Atzmon, Director, Business Development and Marketing, Automotive Cyber Security at Harman commented on the need for additional security in connected cars:
“A few years ago the concept of automotive cyber security was largely confined to industry experts. Now it’s a topic that consumers are asking about. According to a recent survey, in some countries as many as 59% of buyers are actively concerned about the prospect of car hacking.”
In a short statement, Harman announced that it:
“has devised a specially-developed 5+1 security framework which consists of a series of layers that protects the car’s head unit from being compromised and used as a portal into the in-vehicle network (something which could jeopardise safety critical systems)”.
Harman claims its system is like the layers of an onion:
“At the deepest level, a secure hardware platform provides a safe place to store cryptographic keys and execute highly-sensitive operations in a secured manner. Safety-critical functions are isolated from the infotainment system using what’s known as a hypervisor. The next level controls access to the memory, storage and peripherals. It essentially determines who has access to what. Then there is the sandbox function. This keeps newly downloaded applications separate from the core system so they can be disabled and removed if they’re found to be harmful. The fifth level is the network protection system. This controls the flow of information into and out of the car, looking for any signs of intrusion. The final ‘plus one’ level is the ability to install over-the-air (OTA) updates to various systems within the car such as the navigation, engine management and infotainment systems. By keeping the software up to date, it helps to ensure that the car is protected at all times.”
