Wireless sensor networks (WSNs) use small nodes with constrained capabilities to sense,
collect, and disseminate information in many types of applications. As sensor networks …

Security in mobile ad hoc networks is difficult to achieve, notably because of the vulnerability
of wireless links, the limited physical protection of nodes, the dynamically changing …

We describe LEAP+ (Localized Encryption and Authentication Protocol), a key management
protocol for sensor networks that is designed to support in-network processing, while at the …

Pairwise key establishment is a fundamental security service in sensor networks; it enables
sensor nodes to communicate securely with each other using cryptographic techniques …

The topic of information theoretic security is introduced and the principal results in this area
are reviewed. The basic wire-tap channel model is considered first, and then several specific …

Sensor networks are often deployed in unattended environments, thus leaving these
networks vulnerable to false data injection attacks in which an adversary injects false data …

Advances in technology introduce new application areas for sensor networks. Foreseeable
wide deployment of mission critical sensor networks creates concerns on security issues …

In multihop wireless systems, such as ad-hoc and sensor networks, the need for cooperation
among nodes to relay each other's packets exposes them to a wide range of security attacks …

Secure communications in wireless sensor networks operating under adversarial conditions
require providing pairwise (symmetric) keys to sensor nodes. In large scale deployment …

Wireless Sensor Networks (WSNs) have a vast field of applications, including deployment in
hostile environments. Thus, the adoption of security mechanisms is fundamental. However …
