Morris Vysma is an undergraduate Mathematics and Computer Engineering student at the University of Newcastle. In his younger years he had little academic ambitions, leaving school early to pursue easy employment and money. Unsatisfied and less employed than he originally planned he found himself also picking up vocational training in Information Technology at TAFE Western. Here he would spend his time looking for ways to simplify programming assignments and avoid coding as much as possible. After attempting to reduce several projects down to a few lines of undecipherable arithmetic he realized maybe there was something to education after all.
When he had completed 2 Certificate IV’s and 2 Certificate III’s he finally applied to study at a university level, choosing mathematics as a primary interest. He received a position he never actually expected in his highest preference where he was lucky enough to start his first university group assignment with a team of highly motivated mathematics enthusiasts. This would spark a previously undiscovered passion for study, leading to him being placed on the Faculty Commendation List 2014 – Faculty of Science and Information Technology.
With his new found enthusiasm he would start his second year by volunteering to assist with various programs to help kick start new students towards similar goals. In addition he would begin pursuing other personal goals previously dismissed as too hard such as going to the gym, planning an exchange to a non-English speaking country, and dreaming up designs for research projects with real academics in the field.
With a recent extra-curricular fascination for the much miss-interpreted topics of chaos theory and encryption, he is currently working towards not becoming too distracted while he completes the remainder of his undergraduate degree.
Chaos Encrypted Communication Channels
We are using mathematical control theory to build an encrypted communication system. For this we use the chaotic behaviour of the Lorenz system as an encryption key. Sender and receiver need to have synchronised copies of the same Lorenz system. Synchronisation is achieved using coupling and incremental stability properties. Our goal is to estimate the parameters of the encrypted channel, given the parameters of the physical channel. This project will investigate the usefulness of the incremental input-to-state stability concept for this purpose.
