9. PARIS & DARWIN: Securing Wireless Networks DARWIN:Defenses for Attacks of Radio-interference on Wireless Networks • Wireless networks may be subjected to “jamming” attacks that prevent wireless communication. • Defense Strategies: Channel Surfing and Spatial Retreats. PARIS: Privacy Augmented Relaying of Information from Sensors: • Issues that arise because an adversary observes the context surrounding creation/transmission of wireless message. • For tactical networks, Source-Location Privacy focuses on protecting the networked soldier from traceback attacks by adversaries! Interferer Receiver Game Over! Sender
