Crypto & Security Stuffs

Hi, welcome to my research page. I am a Specialist at the Malaysia Cryptology Technology and Management Centre (Pusat Teknologi dan Pengurusan Kriptologi Malaysia - PTPKM). I was previously

a Staff Researcher at MIMOS Berhad (Mar 2022 to Mar 2025),
a Senior Lecturer at the Department of Computer System and Technology, Faculty of Computer Science and Information Technology, University of Malaya (March 2018 until Feb 2022), and
a Staff Researcher at MIMOS Berhad (2010 to 2018).

I received my Bachelor of Science (Computer) in 2004 from Universiti Teknologi Malaysia (UTM) and PhD from Queensland University of Technology, Australia in 2010.

My main research interests are in the area of symmetric cryptography (authenticated encryption, block cipher). I am also interested in application security, cryptographic protocols, and other areas of information security.
