Colloquium - Black

ECCR 265

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.

The Department holds colloquia throughout the Fall and Spring semesters. These colloquia, open to the public, are typically held on Thursday afternoons, but sometimes occur at other times as well. If you would like to receive email notification of upcoming colloquia, subscribe to our Colloquia Mailing List. If you would like to schedule a colloquium, see Colloquium Scheduling.

Sign language interpreters are available upon request. Please contact Stephanie Morris at least five days prior to the colloquium.
