Studying cyber security (theory of cryptographic protocols) for M.Sc. in the Applied Logic And Security (ALAS) lab at Worcester Polytechnic Institute. I am learning how to do research mathematics.

I love to take real-world problems and model them with formal structures and computer programs.

I'm practiced with picking up new languages quickly for one-off projects.

Hobbies: problem solving, critical reasoning, rhetoric, math (esp. graph theory!), economics, cognitive science, political science, and theoretical physics.

Interested in machine learning, especially fields with practical applications that can make a difference in the world such as economics, knowledge sharing, healthcare, bioinformatics, and ecoinformatics.

Deep relationship with Python; Pretty skillful with C++, PHP, Javascript, MySQL, Java, Haskell, Matlab.

comment How practical are side-channel attacks and how much of a concern are they?
This is an interesting question but I'm not sure it has a correct answer. Sounds like a great topic for a discussion thread.

comment Use of nonces in Kerberos and Needham–Schroeder protocols
To elaborate, as @Matteo mentioned, freshness is important not just for messages, but also for keys; if you use the above technique to, say, get a fresh key from a key server, you know that for the duration of the session that the key hasn't been compromised using cryptographic methods (again assuming some reasonable things about how long it takes to compromise a key using cryptographic methods relative to your session timeout).

comment Use of nonces in Kerberos and Needham–Schroeder protocols
I'd say that nonces could indicate their own sort of purely local notion freshness (given reasonable assumptions about what it means to be a nonce). For example when an initiator generates a nonce in a particular session, and in the same session receives a cyphertext containing the nonce and some other stuff securely signed by the responder, the initiator can be reasonably certain that the cyphertext was securely signed by the responder in a recent run.
