0090 312 210 3789 I am an Associate Professor at Department of Cyber Security, Informatics Institute, Middle East Technical University (METU) at Ankara, Turkey. I am Head of Department of Cyber Security and the Director of Cyber Security Center at Middle East Technical University. I left Department of Mathematics of METU and Ecole Polytechnique Federale de Lausanne (EPFL) and RUHR Universität Bochum (RUB) so I am no longer using my email and postal addresses at Germany and Switzerland.
This semester I am teaching 3 courses. You can watch the asynchronous lecture videos from the following Youtube playlists. CSEC 502: Network Security
CSEC 507: Applied Cryptology
CSEC 508: Applied Cryptanalysis

Conference Refereeing
Journal Refereeing 26 February 2018: Although I cryptanalyzed ciphers designed by others all this time, for the first time in my life, as a part of my research at RUB with Gregor Leander, I designed a block cipher. Silent Encryption Decryption Algorithm is the first cipher that is designed specifically for GPU architecture. Click here for the SILENT cipher page. 03 April 2017: I am currently on leave until 2018. I am doing post-doctoral research at RUHR Universitat Bochum, Germany with Gregor Leander's Symmetric Cryptography Group. During my MS and PhD studies, I focused mainly on block cipher cryptanalysis and I discovered the Improbable Differential Cryptanalysis. I provided the best known attacks on the block ciphers HIGHT (standardized at South Korea), CLEFIA (developed by SONY Corporation), and SERPENT (AES candidate). During my PhD studies at EPFL I did reasearch on provable security under the supervision of Prof. Serge Vaudenay and on GHS attack and genus 2 curves under the supervision of Prof. Arjen Lenstra.
