Efficient and Effective Detection of Node Replication Attacks in Mobile Sensor Networks

Abstract

Wireless sensor networks are often deployed in hostile environments, where an adversary can physically capture some of the nodes. Once a node is captured, the attacker can re-program it and replicate the node in a large number of replicas, thus easily taking over the network. The detection of node replication attacks in a wire- less sensor network is therefore a fundamental problem. Compared to the extensive exploration on the defense against node replication attacks in static networks, only a few solutions in mobile networks have been presented. Moreover, while most of the existing schemes in static networks rely on the witness-finding strategy, which cannot be applied to mobile networks, the velocityexceeding strategy used in existing schemes in mobile networks incurs efficiency and security problems. In this paper Localized algorithms are proposed to resist node replication attacks in mobile sensor networks. The Merits of proposed algorithms are, it can effectively detect the node replication in localized manner. These algorithms are, also avoid networkwide synchronization and network-wide revocation.
