Current Courses:
Courses Regularly Taught By Me:
CSC 28: Discrete structures for computer science (Most semesters)
CSC 140: Advanced Algorithm Design and Analysis (Spring of even-numbered years)
CSC 152: Cryptography (Fall of every year)
CSC 252: Cryptography theory and practice (Fall of every year)
I have also taught CSC 1, 130, 132, 148 and 206, but none on a predictable basis.
Research and Projects:
My research focuses on efficient and provably secure symmetric cryptography, especially universal hashing and its applications. If you are interested in trading units for programming, or in working on a supervised project, please come talk to me. (Possible projects.)
Some projects I'm working on:
OCB: Low-overhead authenticated encryption
VMAC: Universal hashing optimized for 64-bit architectures
UH-PRF: A pseudo-random function from {0,1}* to {0,1}* using universal hashing and a stream cipher
UH-PRF-SIV: Using UH-PRF in SIV mode
