Contextual Study of Security and Privacy in Key As A Service (KAAS) for Architecture & Networking products 2024-28-0039

One of the mega trends in the automotive industry, to integrate the car with the smartphone, has opened the adoption of Key-as-a-Service (KaaS). Traditionally, car keys or key fobs have been physical devices that provide entry and ignition capabilities. However, KaaS offers a digital alternative to traditional keys, which allow users to access and operate their vehicles using their smartphones or other digital devices. This innovative approach brings numerous benefits, including user personalization, enhanced security, remote access, and integration along with other digital services and ecosystems. KaaS also opens new possibilities for vehicle sharing and temporary access arrangements. Users can grant access to family members, friends, or service providers for a specific time-period without the need for physical key handovers. While KaaS offers convenience and flexibility, it also introduces potential security risks that must be carefully considered and addressed. It provides an overview of the key concepts and technologies involved in KaaS, including the use of near-field communication (NFC) and mobile applications. The paper examines the potential vulnerabilities and threats that may arise in the context of KaaS, such as unauthorized access, key theft, identity theft and malicious attacks targeting the digital key infrastructure. By understanding the potential security risks and implementing appropriate safeguards, the industry can reap the benefits of KaaS while safeguarding the privacy, integrity, and security of automotive systems and user data. Keywords: Key as a Service, KaaS, automotive security, Key fob, near-field communication, autonomous driving, remote access, cybersecurity. List of Abbreviations: KAAS – Key as a Service, NFC – Near field Communication
