Remote Keyless Entry

Remote Keyless Entry (RKE) is an electronic access control system that allows users to lock or unlock a vehicle from a distance using a radio frequency fob. Its security is a core component of automotive cybersecurity, governed by standards like **ISO/SAE 21434**. This standard mandates a systematic Threat Analysis and Risk Assessment (TARA) for RKE systems. Early RKEs used fixed codes vulnerable to replay attacks; modern systems use rolling codes, where the code changes with each use, significantly enhancing security. RKE is distinct from Passive Keyless Entry (PKE), which operates automatically based on proximity without requiring a button press.

In enterprise risk management, particularly for automotive OEMs, applying RKE security follows the **ISO/SAE 21434** framework. The process involves three key steps: 1) Conducting a Threat Analysis and Risk Assessment (TARA) to identify vulnerabilities like signal interception and jamming. 2) Implementing security controls, such as using strong cryptographic algorithms like AES-128 (often validated under **NIST FIPS 140-2**) for the rolling code mechanism. 3) Performing continuous validation through penetration testing and post-launch monitoring via a Product Security Incident Response Team (PSIRT). This structured approach helps automakers reduce theft-related warranty claims by over 60% and achieve a high pass rate in third-party security audits.

Taiwanese enterprises, often key suppliers in the automotive electronics chain, face several challenges: 1) **Supply Chain Security Management**: Meeting stringent cybersecurity requirements from multiple OEMs under **ISO/SAE 21434** is complex and costly. 2) **Regulatory Compliance**: Adhering to regulations like **UN R155** for vehicle type approval in export markets like the EU requires significant investment in process and documentation. 3) **Evolving Threats & Talent Gap**: Keeping pace with sophisticated attacks (e.g., relay attacks, RollJam) is difficult due to a shortage of specialized automotive cybersecurity talent. Mitigation strategies include establishing a unified Cybersecurity Management System (CSMS), forming a dedicated regulatory task force, and partnering with expert consultants to upskill internal teams.
