    Séminaire LARIS - Lachlan J. GUNN, The University of Adelaide, Australie

    à 9h15 en salle 118 de l'ISTIA

    Le 4 novembre 2014

    "The Kish Key Distribution System: A classical alternative to quantum key distribution"
    Public key cryptography has raised cryptography from a curiosity, useful mainly to governments, to its status as a pillar for modern communications [1]. But above this magnificent throne hangs a sword of Damocles in the form of quantum computing, motivating the development of new approaches.Some have turned to physics, developing systems with security guarantees based on natural laws. The most popular is Quantum Key Distribution, but its complexity has spurred the development of alternatives.We examine the Kish Key Distribution system (a method of secret communication using noise) [2], an entirely electronic system, charting the attacks and countermeasures that have been introduced since its introduction in 2006 [3].

    Lachlan J. GUNN received a Bachelor of Engineering with Honours (Electrical and Electronic Engineering) and a Bachelor of Science with Honours (Math and Computer Science), both from the University of Adelaide, Australia in 2012. In 2012, he won the J. Mazumdar Prize in Engineering and Mathematics. In the 2009-2012 period he was awarded four Defence Science and Technology (DSTO) scholarships in Radar Technology. In 2010, he was awarded a DSTO Summer Vacation Scholarship and undertook research into sea-clutter simulation. From 2012 to 2013 he was a student engineer at Minelab Electronics Pty Ltd, working primarily in the areas of electromagnetic physics and analogue design. In 2013, he was granted a prestigious Australian Postgraduate Award (APA) scholarship, and is currently undertaking a Ph.D. under Derek ABBOTT and Andrew ALLISON at the University of Adelaide. His research interests include information-theoretic security and the use of stochastic signal processing for system identification. Scientific collaboration has been going on for almost 10 years in the LARIS with the group of Prof. Derek ABBOTT of the School of Electrical and Electronic Engineering, The University of Adelaide, Australia, with more than 15 coauthored research papers, on stochastic signals and useful-noise effects. Lachlan GUNN is currently applying for a travel fellowship from the Australian Government, for a stay of 6 months (Sept. 2015 to Feb. 2016) in the LARIS to continue the collaboration.
