By security, I mean cryptography, intrusion detection systems, firewalls, and web-based attacks (like SQL injection, XSS, and the like). I consider computer security to be equal parts mathematics and engineering (even the best cryptosystems can be engineered poorly and introduce weak points).

I'm taking a course (in the mathematics department) on elliptic curve cryptography, and I am a new member on UF's infosec team. I'll be competing in this year's iCTF, so that should help give you an idea of what I mean by security and what I'm interested in researching.
