Intelligent modern vehicle has more MCUs (micro controller units) and more software code than ever, which comes with cyber risks. Cyber security in automotive electronics poses greater challenges than in ordinary computers because of limited connectivity, low computational performance, unclear threat models and critical hazards to drivers or passengers' safety. For this reason, we apply the ISO-26262 concept of "Functional Safety" for vehicle cyber security. In this approach risks are assessed according to the following three scales: "Exposure", "Severity" and "Controllability" and more critical functions are taken measures with higher priorities. In this paper, we introduce this approach in the case of the vehicle (center-console) terminals which include functions such as audio control, Navigation, and air conditioner control. Finally, this approach can be applied to broader embedded systems with limited external connectivity and low computational performance.

advanced wireless technologies. However, the radio channel on the road presents many
challenges to the connected car technologies, including motion of the radios located in
vehicles, multipath caused by close proximity of moving reflectors, such as cars and trucks
and Doppler fading of the radio signal due to the motion of both radios and reflectors. To
ensure success of the connected vehicle Dedicated Short-Range Communications (DSRC)
technology, we have to consider and measure the impact of real-world challenges to radios
operating on the roads. To this end, the industry has been pursuing three approaches:
computer simulations, field testing and radio channel emulation. In this paper we will
examine the benefits and trade-offs of these three approaches with the focus on radio channel
emulation, which involves placing real radios into a controlled laboratory-based wireless
testbed.
