Selected Publications

PhyForm - A cloud SDR framework for security research supporting machine learning of wireless IoT signal data sets

Demonstration at EWSN 2020

SDR enables the use of DSP to identify IoT security issues based on waveform analysis. Such research requires the handling, processing and interaction with large data sets of digitised RF. An extensible framework is introduced for the curation, filtering, pre-processing, and analysis tasks associated with RF data sets in machine learning and IoT research. A LoRa example provides context.

Combined secure storage and communication for the Internet of Things

Contributor to Paper at SECON 2013

A framework is presented that combines secure storage with compressed IPsec in IPv6. A prototype implementation shows that combined secure storage and communication reduces the security-related processing on nodes.

Implementation and Evaluation of Distance Based Message Authentication

Paper at IEEE MASS 2010

A practical implementation of Distance Based Message Authentication (DBMA) for WSNs using Nanotron NA5TR1 transceivers is shown. DBMA can be used to reject messages sent from outside a secure (trusted) area. The implementation is evaluated in two different scenarios. Distance measurement errors and their impact on the size of the required secure area are evaluated.

DHB-KEY: An Efficient Key Distribution Scheme for Wireless Sensor Networks

Paper at IEEE MASS 2008

A key distribution scheme based on Elliptic Curve Diffie-Hellman is presented that allows a network individual keys to be replaced using a single broadcast message. This preserves scarce resources such as bandwidth and energy. An implementation is evaluated using the TinyOS platform and demonstrated using a system in an office building.
