Keyless Entry Systems Security – PlaxidityX Ep 12

Keyless entry systems, once considered the pinnacle of vehicle convenience, are now a major target for hackers and car thieves. In today’s episode, we’ll explore the vulnerabilities in Remote and Passive Keyless Entry (RKE/PKE) systems, focusing on how replay, relay, and roll jam attacks exploit their weaknesses.

We break down these attack methods, illustrating how hackers bypass rolling codes, exploit weak cryptographic implementations, and outsmart proximity-based systems. We’ll also discuss practical solutions, such as implementing high-entropy cryptographic functions, RSSI localization, motion sensors, and ensuring automotive security compliance.

If you’re curious about OEMs' cyber security advancements and how technology like OTA updates can mitigate vulnerabilities, this episode is a must-listen for understanding the future of car cybersecurity.
