About Me

I worked from September 2009 to August 2011 as a postdoctoral researcher in the crypto group led by professor Kaisa Nyberg. Before that, I did my PhD in the team SECRET at INRIA Paris-Rocquencourt. Right now I'm employed at Cryptolog in Paris, France.

Research

My research interests lie in symmetric cryptography. I was working on random number generators and especially on the entropy estimation of random sources, on stream ciphers, on hash functions and on linear cryptanalysis of block ciphers.
