Mitigation Of Control Channel Jamming Under Node Capture Attacks, Patrick Tague, Mingyan Li, Radha Poovendran
Mitigation Of Control Channel Jamming Under Node Capture Attacks, Patrick Tague, Mingyan Li, Radha Poovendran
Patrick Tague
Availability of service in many wireless networks depends on the ability for network users to establish and maintain communication channels using control messages from base stations and other users. An adversary with knowledge of the underlying communication protocol can mount an efficient denial of service attack by jamming the communication channels used to exchange control messages. The use of spread spectrum techniques can deter an external adversary from such control channel jamming attacks. However, malicious colluding insiders or an adversary who captures or compromises system users are not deterred by spread spectrum, as they know the required spreading sequences. For …

Evaluating The Vulnerability Of Network Traffic Using Joint Security And Routing Analysis, Patrick Tague, David Slater, Jason Rogers, Radha Poovendran

Joint analysis of security and routing protocols in wireless networks reveals vulnerabilities of secure network traffic that remain undetected when security and routing protocols are analyzed independently. We formulate a class of continuous metrics to evaluate the vulnerability of network traffic as a function of security and routing protocols used in wireless networks. We develop two complementary vulnerability definitions using set theoretic and circuit theoretic interpretations of the security of network traffic, allowing a network analyst or an adversary to determine weaknesses in the secure network. We formalize node capture attacks using the vulnerability metric as a nonlinear integer programming …

Tradeoffs Between Jamming Resilience And Communication Efficiency In Key Establishment, Patrick Tague, David Slater, Radha Poovendran, Brian Matt

We address the problem of allowing authorized users, who do not preshare a common key, to effectively exchange key establishment messages over an insecure channel in the presence of jamming and message insertion attacks. In this work, we jointly consider the security and efficiency of key exchange protocols, focusing on the interplay between message fragmentation, jamming resilience, and verification complexity for protocol optimization. Finally, we present three fragment verification schemes and demonstrate through analysis and simulation that in comparison with existing approaches, they can significantly decrease the amount of time required for key establishment without degrading the guaranteed level of …
