Radio-Controlling Street Lamps and Power Plants - Security Analysis and Vulnerabilities

Explore a comprehensive conference talk from the 38th Chaos Communication Congress that examines the vulnerabilities in Europe's radio ripple control system for renewable energy infrastructure. Dive into the technical details of how longwave radio signals control street lamps, heating systems, and power generation across multiple European countries through the EFR (Europäische Funk-Rundsteuerung) GmbH network. Learn about the unencrypted Versacom and Semagyr protocols, their weaknesses, and potential security implications through detailed protocol analysis, hardware hacking demonstrations, and proof-of-concept attacks. Understand both the stabilizing benefits and potential risks of this system that manages over 1.3 million receivers and multiple gigawatts of renewable power generation across Germany, Austria, Czechia, Hungary and Slovakia. Discover practical demonstrations, implementation techniques, and future security considerations for this critical infrastructure technology.
