Lightweight, Distributed Access Control for Wireless Sensor Networks Supporting Mobility

Abstract

Wireless sensor networks (WSN) are large scale networks of unattended devices, aimed at monitoring environmental parameters. Their extremely scarce hardware resources constitute a huge limitation to the use of standard security protocols to secure communications, so that custom ones must be designed. In this article we describe the development of a novel access control system for WSN based on a distributed threshold scheme. Our model gives support for mobility and limits the needed communication and consequent energy drain, which is a fundamental parameter for the lifetime of WSN.

Reactive on-board regulation of cognitive radios

“…The resulting diversity therefore increases the complexity associated with the enforcement of fair and effective usage of the wireless medium by a cognitive radio network. This problem is often addressed using a trusted third party or distribution of trust [11,12]. Such system incur significant overhead or in certain scenarios, assumption of a trusted third party is not always practical.…”

Reputation-based role assignment for role-based access control in wireless sensor networks

“…In previous years, a number of research works have been done and a number of others are also in progress both on access control models [1,4,5,7] and reputation-based systems [13][14][15][16]26,29] for wireless networks. Before we proceed towards describing our work, let us provide a brief review of some of the existing and popular access control and reputation based schemes that motivated our work.…”

“…Introducing security mechanisms generally involves introducing cryptographic methods, which require high memory usage and power consumption in processing and communication. Many researchers have already proposed many security measures and most of them involve cryptographic methods and techniques [1,[3][4][5][6][7][8][9][10][11][12][35][36][37][38].…”

A Cross-Layer Security Scheme of Web-Services-Based Communications for IEEE 1451 Sensor and Actuator Networks

“…Recently, schemes related to the cyber security for sensor and actuator networks have been widely investigated [20][21][22][23][24]. In particular, cyber security of Web-services-based communication for smart transducers must be implemented [25].…”
