Cryptographic hash functions
Cryptographic hash functions are essential for the security of many applications, including digital signatures, the derivation of cryptographic keys and in commitment schemes. As several popular hash functions, e.g. MD5 and SHA1, were broken, there is a need for new and better hash functions to replace them. My research interest lie both in the analysis and the design of cryptographic hash functions.
In 2008, the National Institute of Standards and Technology (NIST) started an international, public competition, which is expected to continue until 2012. It aims to develop a new cryptographic hash standard that will be called SHA-3. I am the main designer of the hash function Lane, one of the candidates in this competition. Currently, I focus on the cryptanalysis of other candidates. So far, I've been involved the cryptanalysis of the SHA-3 candidates Dynamic SHA, EnRUPT, Maraca, and SHAMATA.
I'm a Ph.D. student in the COSIC research group of Katholieke Universiteit Leuven, Belgium. My promotor is prof. Bart Preneel. I'm funded by a PhD grant from the Flemish Research Foundation (FWO aspirant).
