Car doors can now be conveniently opened by smart devices. Whereas it was once necessary to prevent keys from being refiled, the task now is to make relay station attacks impossible. The requirements for the security of locking systems in cars are becoming more complex and are shifting into cloud- and software-based realms.
How theft-proof new cars and their locking systems are is checked, for example, by the British driving safety institute Thatcham Research. Key factors for a good hands-free access system are accurate location and prevention of signal extension by third parties.
Compared to other radio technologies, UWB achieves an enormously high level of localization accuracy - around the entire car as well as in the cabin. The system therefore precisely detects whether the authorization key is in the car and only then enables the engine to be started. Relay station attacks, in which thieves can extend radio signals and thus open cars, are not possible with this technology.
The localization algorithms of Huf Phone as a Key are designed to meet the highest security requirements and allow only a minimal tolerance range. Phone as a Key thus meets Thatcham security requirements and offers a high level of theft protection.
ISO/SAE 21434: Cyber security management system for cars
The ISO/SAE 21434 standard "Road cars - Cybersecurity engineering" is a cyber security standard for cars. It applies to OEMs as well as system integrators and suppliers in the automotive industry. It was developed by a working group of the International Organization for Standardization (ISO) and the Society of Automotive Engineers (SAE). The central points of the standard are threat analysis and risk assessment as well as the security of all electrical and electronic systems during the entire life cycle of a car.
The process-oriented standard goes hand in hand with the EU regulation on cyber security. The Economic Commission for Europe (UN/ECE) has accordingly developed a certification for a cyber security management system (CSMS): Since July 2022, a mandatory proof for a cyber security management system in the automotive sector is required according to UN/ECE 155.
Huf Phone as a Key complies with ISO/SAE 21434. The global Phone as a Key team has conducted a comprehensive analysis and risk assessment, providing customers with a confident assessment in line with the new standard to identify and prevent early points of attack in the digital space.
Huf thus continues to be at the forefront of new technological developments - as it has been for more than 100 years - and, as a member of the CCC, is actively shaping the future of mobility.
