Car access via smartphone: Phone as a Key, the digital car key by Huf, combines three advanced technologies for data transmission to provide a comfortable and secure hands-free car access experience. The combination of Ultra Wideband (UWB) and Bluetooth Low Energy (BLE) provides high-precision localization that makes relay station attacks impossible. Moreover, the AUTOSAR-compliant system by Huf enables high energy efficiency.

Phone as a Key by Huf provides drivers with a whole new range of everyday functions. In addition to the easy sharing of digital car keys, numerous innovative comfort and security functions are extending the scope of the hands-free access via smartphone. Phone as a Key makes driving even more convenient and safe.

Systems for managing digital keys must be compatible with as many devices as possible and be able to be integrated into different car architectures. That is why Huf has made sure that the Phone as a Key digital car key meets important standards. This ensures that both OEMs and suppliers can easily integrate all hardware and software components.

As of July 2022, UNECE Regulation 155 is mandatory. Since then, automotive manufacturers must prove that products and processes have been certified according to ISO/SAE 21434. Automotive suppliers not only contribute to these cyber security requirements, but also have to work through even more complex checklists of the car manufacturers.

ISO/SAE 21434 is the standard for cyber security in automotive industry: supplier Huf supports its customers in every respect – from first idea to serial product and beyond.

It is a moment awaited with eager anticipation by many car buyers: the official handover of the car key. After all, with this symbolic act, the buyer knows that “now the car is finally mine.” With the new Concept Key, Huf shows what the future of the car key looks like and how it will lead a meaningful coexistence with digital keys on smartphones and NFC cards.
