TLDR
This paper surveys the state of art in securing wireless sensor networks, with an emphasis on authentication, key management and distribution, secure routing, and methods for intrusion detection.Abstract:
With sensor networks on the verge of deployment, security issues pertaining to the sensor networks are in the limelight. Though the security in sensor networks share many characteristics with wireless ad hoc networks, the two fields are rapidly diverging due to the fundamental differences between the make-up and goals of the two types of networks. Perhaps the greatest dividing difference is the energy and computational abilities. Sensor nodes are typically smaller, less powerful, and more prone to failure than nodes in an ad hoc network. These differences indicate that protocols that are valid in the context of ad-hoc networks may not be directly applicable for sensor networks. In this paper, we survey the state of art in securing wireless sensor networks. We review several protocols that provide security in sensor networks, with an emphasis on authentication, key management and distribution, secure routing, and methods for intrusion detection.

A key-management scheme for distributed sensor networks
TL;DR: A key-management scheme designed to satisfy both operational and security requirements of DSNs is presented, which relies on probabilistic key sharing among the nodes of a random graph and uses simple protocols for shared-key discovery and path-key establishment, and for key revocation, re-keying, and incremental addition of nodes.

Mitigating routing misbehavior in mobile ad hoc networks
TL;DR: Two techniques that improve throughput in an ad hoc network in the presence of nodes that agree to forward packets but fail to do so are described, using a watchdog that identifies misbehaving nodes and a pathrater that helps routing protocols avoid these nodes.

Random key predistribution schemes for sensor networks
TL;DR: The random-pairwise keys scheme is presented, which perfectly preserves the secrecy of the rest of the network when any node is captured, and also enables node-to-node authentication and quorum-based revocation.

Chris Karlof,David Wagner +1 more
TL;DR: This work proposes security goals for routing in sensor networks, shows how attacks against ad-hoc and peer-to-peer networks can be adapted into powerful attacks against sensors, and introduces two classes of novel attacks against sensor networks sinkholes and HELLO floods.
