Brief audio fragment labeled as Schneier Tradecraft on Public Networks from DEF CON 6.
Summary
Cryptographer and author Bruce Schneier delivers a presentation on espionage tradecraft and covert communications across public networks on the Main Stage at DEF CON 6.
Schneier examines classic intelligence tradecraft—including dead drops, visual semaphores, cutouts, and tamper-evident telltales—and evaluates how operational security principles adapt to digital computer networks under pervasive surveillance. He explores whether covert communication remains achievable across open communication channels, assessing the defensive strengths and limitations of encryption algorithms, traffic analysis countermeasures, and digital steganography designed to protect operational security against well-resourced adversaries.
