Research Topic Description, including Problem Statement:

  • The security of wireless communications at the physical layer is often considered to be ineffective because of ease with which measures can be circumvented. However, we know that there is potential to significantly increase the cost of interception of wireless communications by a potential eavesdropper by matching transmitter and receiver and/or forcing the eavesdropper to use N-channel techniques.

  • The goal of the project will be to examine approaches to increasing physical security of wireless communications through modification of the EM field, and to identify how these techniques can be assessed. It will involve modelling the cost and complexity imposed on any potential eavesdropper and suggest rules for designing to the risk. An important distinction is the probability of detection and the probability of interception (both with and without apriori knowledge) as these are different in range and cost.

  • It is essential that theory and modelling stages are linked fully through to tangible evaluation.


Example Approaches:

  • Two techniques have been considered: Orbital Angular Momentum (which generates the illusion of high order rotation in the EM field by superposing phased contributions from a circularly disposed array of antenna elements); Direct Digital Modulation (DDM) (also known as Direct Antenna Modulation) which uses superpositioning of contributions to the symbols from a linear array of antenna elements so that the constellation is only resolvable on-axis over a range determined by the antenna spacing. An aspect not examined as yet is the potential security advantage of an evanescent Bessel field (or other novel non-radiative fields) for short range communication.
