Recent study has demonstrated that quite a few well-know pairwise key establishment schemes are susceptible to key-swapping collusion attack aiming to subvert crucial applications that require cooperative efforts, e.g., data fusion algorithms, routing protocols, etc. Previous works against this attack have shown their own limitations. To overcome these limitations, we propose a new countermeasure...
Traditional routing protocols deployed to provide communication among mobile nodes in wireless ad hoc networks (MANET) assume a trust and collaborating environment inside the network. However, this assumption is not always true and a hostile or unprotected environment can seriously affect the protocol and network performance. In this work two kinds of approaches are applied to a well-known routing...
In this paper, we address the security of routing protocols. Internet routing protocols are subject to attacks in the control plane as well as the data plane. In the control plane, a routing protocol, e.g., BGP, OSPF, exchanges routing state updates and enables routers to compute the best paths towards various destinations. During this phase, an attacker can modify or inject malicious control messages...
We investigate the impact of node capture attacks on the confidentiality and integrity of network traffic. We map the compromise of network traffic to the flow of current through an electric circuit and propose a metric for quantifying the vulnerability of the traffic using the circuit mapping. We compute the vulnerability metric as a function of the routing and the cryptographic protocols used to...
