My name is Ammar Alkassar, born in 1976 in the great city of Aachen. Since 2000 I am researcher at the Cryptography and Security Research Group with the Computer Science Department at Saarland University.

- Working on my PhD in computer science.
- Managing some research projects (UniSteP former UniSeT, FIDIS @SB, NoE)

- Research areas: Cryptography, security and communications engineering,
- cryptographic protocols and secure key exchange,
- security in adhoc networks, game theory and identification,
- ISDN, ATM and high speed networks,
- secure telecommunications and critical infrastructres.

More Invited Talks, I have been given at EPFL Lausanne, Naval Postgraduate School Monterey, Bochum University, NATO 3C Agency,Stevens Institute of Technology, NJ and others.

At the summer-term 2003 I gave a lecture on "Selected Areas in Cryptography" (2V2Ü, 6 credit points; English). This course will deal with both basic cryptographic foundations like formal proof settings as well as complex cryptographic protocols. Some of the topics will be Secret Sharing, Byzantine Agreement, (Bit-)Commitments, Oblivious Transfer and Zero-Knowledge Proofs.

The lecture takes place on Thursday, 14-16 pm and Friday, 11-13 in hall 0.16.
