Abstract
This paper describes a novel re-keying function protocol (NRFP) for wireless sensor network security. A re-keying process management system for sensor networks is designed to support in-network processing. The design of the protocol is motivated by decentralization key management for wireless sensor networks (WSNs), covering key deployment, key refreshment, and key establishment. NRFP supports the establishment of novel administrative functions for sensor nodes that derive/re-derive a session key for each communication session. The protocol proposes direct connection, in-direct connection and hybrid connection. NRFP also includes an efficient protocol for local broadcast authentication based on the use of one-way key chains. A salient feature of the authentication protocol is that it supports source authentication without precluding innetwork processing. Security and performance analysis shows that it is very efficient in computation, communication and storage and, that NRFP is also effective in defending against many sophisticated attacks.
Highlights
Sensor networks can consist of hundreds or even thousands of sensor nodes, low power devices equipped with one or more sensors
novel re-keying function protocol (NRFP) is described as a sensor network security re-keying function protocol that is designed to support decentralized key management architecture for wireless sensor networks (WSNs), while providing security properties similar to those provided by session key schemes
At the end of the restructuring cluster and when the session key has been performed, the cluster head derived shared key is sent to the base station where it is used in future communication between clusters
Summary
Sensor networks can consist of hundreds or even thousands of sensor nodes, low power devices equipped with one or more sensors. A sensor node typically contains signal processing circuits, microcontrollers, and a wireless transmitter/receiver These components, if implemented without any security, could become a point of attack. Despite sensors being used in many important applications, recent research has not focused adequately on the issue of security and protection, emphasizing instead on energy efficiency [2], network protocols [3] and distributed databases. An important design consideration for security protocols based on symmetric keys is the degree of session key between the nodes in the system. NRFP is described as a sensor network security re-keying function protocol that is designed to support decentralized key management architecture for WSNs, while providing security properties similar to those provided by session key schemes. The premise of NRFP is that no single keying mechanism is appropriate for all of the secure communications that are needed in sensor networks.
