Colloquium - Black

Cryptography and Cryptanalysis: Recent Results on Collision-Resistant Hashing and a Dubious Security Protocol
Department of Computer Science

Two and a half years ago, I gave an interview talk at CU which focused on my prime area of research: cryptographic algorithms that are provably secure and that go fast on commodity hardware. In this talk, I will first update my research in this area, and then focus on two new projects currently underway.

The first is some recent research investigating collision-resistant hash functions based on blockciphers. Then I will describe a recently-conducted security analysis where several flaws in a widely-used piece of Internet software were uncovered. This has led to some interesting questions for further research that will also be discussed, time permitting.
