The Release 1.0 specification provides a generalized deployment method that allows vehicle OEMs to securely transfer a digital key implementation to a smart device, using an existing Trusted Service Manager (TSM) infrastructure. By leveraging NFC distance bounding and a direct link to the secure element of the device, CCC is assuring the highest state-of-the-art security level for vehicle access.
Car manufacturers will use an existing trusted system to send the digital key to your phone, which uses close-range NFC to grant access to your ride. You can’t just unlock your car from inside your home, then, but this would also force would-be thieves to be physically present with your phone when trying to unlock your car.
Targeted for completion in Q1 2019, Release 2.0 will provide a standardized authentication protocol between the vehicle and smart device. By joining forces, Release 2.0 will deliver a fully scalable solution to reduce development costs for adopters and ensure interoperability between different smart devices and vehicles.
BMW is currently offering a Digital Display Key for several models. Besides all the convenience functions of a remote key – unlocking, locking and failsafe identification of the key for starting the vehicle – this key fob also shows vehicle status displays on a 2.2-inch LCD screen.
