NXP Semiconductors announced a new automotive Digital Key Solution that enables smartphones, key fobs and other mobile devices to securely communicate, store, authenticate and share digital keys with vehicles. The solution expands the convenience of car access by providing the secure basis required to enable new features like key sharing, multi-car access, and configurable driving rights. Built on NXP’s automotive-qualified Secure Element and NFC chipsets, the solution follows the Car Connectivity Consortium’s Standardization Release 2, an architecture that is endorsed by the world’s leading carmakers, smartphone manufacturers and electronics suppliers.

The Digital Key Solution, comprised of NXP’s NFC chipsets and Secure Element technologies, including the new automotive-qualified NXP Secure Element, enables the unlocking and starting of a car with an NFC-enabled smartphone, key fob or an NFC Smart Card holding a digital key. It also enables the secure sharing of vehicle access with other mobile devices, an advanced capability for the secure car access ecosystem. It can be seamlessly added to classic remote or passive entry systems.

End-to-end security is enabled by NXP Secure Elements on both the mobile and car sides. Embedded Digital Key applets support ecosystem interoperability leveraging CCC’s standardization. The solution includes NFC technology to trigger car access and driver authorization, even if a phone’s battery is low.

Secure digital key management is also the basis for enabling hands-free smart car access which will be defined in CCC Release 3. Therefore, NXP is set to combine its digital key solution with its automotive Bluetooth (BLE) for communication and its recently announced Ultra-Wideband (UWB) technology for precise and secure localization.

NXP expects great strides in convenience based on the digitalization of car access, made possible by secure and interoperable standards. The end-to-end security of NXP’s digital key solution links a range of devices with vehicles, helping to create secure connections for a smarter world.
