The Wireless Sensor Network Security project aims to improve the security of Wireless Sensor Networks (WSNs) used in scenarios with high security requirements. The project has the following objectives:

• Identify the characteristics and limitations of WSN architectural design.
• Identify the security requirements in a variety of real scenarios.
• Review the existing security offerings.
• Propose and evaluate improved security protocols.
• Evaluate the impact of these improvements in high security scenarios.

Background

Wireless Sensor Networks (or WSNs) are an emerging technology used for distributed sensing and actuation tasks in a variety of scenarios. WSNs are characterised by a distributed, but locally constrained, architecture.

There is considerable research movement in the area, and increasing industrial activity, but security has been largely overlooked. Where security is available, it tends to be inadequate or inefficient in high security scenarios.

Publications

Work has now been published in two areas. The first publications involved the development of a key distribution protocol for end-to-end security applications, this helped to improve the distribution of network load during rekeying.

The second publications involve the development of a physical-layer message authentication protocol to protect higher layers from denial-of-service attacks.

Related Research Areas

My work has involved work in closely related areas such as public key cryptography, broadcast authentication, IPsec, Wifi, IEEE 802.15.4, Ultra-wideband, vehicular communication and localisation. There is considerable overlap into related fields such as radio science, smart cards, embedded systems and Internet protocol.
