Interests

My work focuses on the security of air-to-ground communications systems and protocols in use for aviation. It takes a long time to develop technologies used in civil aviation; once a product is built and tested, it has to be certified and integrated before it makes its way onto an aircraft. Since most of the systems in use today were not designed with security in mind - or before attacks became feasible - they have a wide install base but rarely have any security provision in place. Rolling out patches or upgrades is equally as difficult as deploying new systems, which means that security solutions have to avoid replacing the original system whilst still trying to fix the problem. This gap is roughly where my work sits.

I am part of the System Security Lab under Ivan Martinovic, which looks at a range of topics from biometric authentication to wireless security.
