Formal Security Analysis of Critical Infrastructure
Tom Chothia
Senior Lecturer in Cyber Security, University of Birmingham
By applying formal, mathematical techniques to analyse high integrity systems we can find weaknesses that other analyses miss. I will give an overview of some of our past work in this area, which used the tool ProVerif to analyse the security of embedded devices, including a security analysis of e-passports and EMV bank cards. I will then describe how we are developing these techniques to be applicable to large scale systems, and how we are using these to find attack vectors against proposed next generation rail systems.
