I'm  working at the COSIC lab of the Department of Electrical Engineering (ESAT) of the K.U.Leuven. You can get an idea of the place from this picture I've drawn for you.

My research topic is cryptography in general, and as such I'm member of the International Association for Cryptographic Research. If you have any questions concerning cryptography, you first might want to have a look at a FAQ page. If you did have a look, and you now have even more questions on cryptography, or if you simply want to read the best book on cryptography, then order immediately your copy of the one and only Handbook of Applied Cryptography! I hope I haven't lost you by now. I'm primarily interested in all issues related to the implementation of cryptographic algorithms. Research topics include, but are not limited to, fast and flexible implementations, both in (portable) C and (non-portable) Intel Assembler, of

In this respect the multiple-issue (superscalar/VLIW) architecture of the current generation of CISC and RISC processors opens up exciting new perspectives! New results on implementations of cryptographic algorithms taking advantage of these parallel architectures are always welcome.

The implementation page gives an overview of the Pentium-optimized implementations I have written of the following algorithms:

More information on the status of MD5 and why you might consider to switch to RIPEMD-160 is available on the RIPEMD-160 homepage. project.

The proceedings of the sixth edition of the ESAT-COSIC biannual Summer School on cryptography are available in the Springer LNCS series. The tenth edition of this summer school will take place in June 2005.

Every two weeks you can attend our COSIC seminars. Be there or be square!
