I am an assistant professor at Cyberspace Research Institute at Shahid Beheshti University, Iran, since 2015. My major research interest is  applied cryptography, focusing on cryptanalysis of symmetric key primitives and techniques to apply side-channel attacks on cryptographic algorithms.

I did my Ph.D. at Aalto University in Finland under the supervision of Prof. Kaisa Nyberg. My dissertation can be found here. My work was funded by the Helsinki Doctoral Programme in Computer Science – Advanced Computing and Intelligent Systems (HECSE) and partially by the European Commission through the ICT program ECRYPT II.

In summer 2016 and 2017, I was a postdoctoral researcher at Technical University of Denmark (DTU), as part of the Cyber Security group which I worked with Prof. Christian Rechberger.

Current Research

My major research interest is applied cryptography, focusing on cryptanalysis of symmetric key primitives and techniques to apply side-channel and fault attacks on cryptographic algorithms.

Ph.D. Research

My primary research goal during my Ph.D. study was to develop cryptanalysis methods for determining the exact security level of some inventive and unconventional designs for lightweight block ciphers.  My dissertation can be found here.

Postdoc Research

In my short postdocs, I evaluated the security of the novel block ciphers designed for specific applications like secure multi-party computation (MPC) or fully homomorphic encryption (FHE).
