Spatial-Domain Wireless Jamming with Reconfigurable Intelligent Surfaces

Wireless communication is fundamental to modern life, underpinning everything from smart home devices to critical infrastructure. However, the inherent openness of the wireless channel exposes these systems to various security threats, with **wireless jamming** being a long-standing and well-studied concern. Traditional jamming attacks typically involve an attacker broadcasting a strong interfering signal, effectively disabling all wireless devices within their operational range, leading to a denial-of-service condition. While effective, this broad-stroke approach lacks precision and can be easily detected.
AI review
Solid, original wireless security research that weaponizes RIS technology in a way the field hasn't fully confronted yet. The two-phase attack — greedy passive optimization plus channel-reciprocity-based jamming — is technically clean and the 5mm proximity result is the kind of concrete, uncomfortable finding that makes a conference worth attending.
