Current work

I completed my PhD in 2012, with a thesis entitled "Statistical methods for non-profiled differential side-channel analysis: Theory and evaluation". I continue to investigate topics related to DPA, including (so-called) 'generic' methodologies, device profiling and power models, applications of machine learning methods, applications of high performance computing, and new approaches to 'multivariate' leakage exploitation.
