Connectivity has long since become a matter of course in everyday life outside the car, although it carries the risk that attackers will disrupt or even manipulate the system. That’s why the connected car requires a high level of security while communicating to a world of data beyond the vehicle, including cloud, Internet, other vehicles (Car2X), telematics systems or vendor-specific services.
The Smart Antenna is a central device providing telematics services to the car via various interfaces such as mobile radio standards, GNSS, radio tuner, Bluetooth and others, while providing protection against malicious attacks. The controller integrated in the antenna processes the signals received and transmits them to the appropriate device in the car and vice versa. Transmission formats are Bluetooth LTE, GSM, Wifi, TVB-T2, FM, 3G, 4G, 5G, etc.
Smart Antennas, based on OpenSynergy’s virtualization platform COQOS Hypervisor SDK, provides a high level of security: the hypervisor technology as the key component. It creates independent, separated virtual machines (VMs). Several communication stacks with different safety levels such as Car2Car communication, C2I or Car2Cloud can be integrated separately from each other in these VMs, keeping the trusted domain separate from the untrusted for security reasons.
The separation due to the VMs act as a firewall and securely protects against attacks from outside, so if one of the VMs has been attacked by malicious software, it cannot affect any of the other VMs.
OpenSynergy also delivers the pre-integrated AUTOSAR environment COQOSAR in separated VM. This VM has a direct CAN connection. Signals received via the antenna can be forwarded from the Linux VM to COQOSAR via the OpenSynergy (ACF) Automotive Communication Framework. Alternatively, the Smart Antenna sends processed data via Ethernet to in-vehicle network.
Smart Antenna gives the driver access to a high number of services reducing the amount of hardware in the vehicle. Moreover, it minimizes heat inside the antenna and optimizes the design of the antenna located on top of the car.
