I'm currently studying Engineering in a European university (not CEng, though), and I've always been fascinated by the network security/information security field.
As far as I know, crypto is the most math-heavy specialization out there, but it typically uses abstract algebra and number theory. What about other fields, such as probability or control theory?
My control systems textbook quoted some applications of control theory to congestion control of Web servers, but didn't elaborate much further.
Is there any application of control theory to information security?
