Research Interests

  • My research interest focuses on the algebraic aspects of symmetric key cryptosystems and their cryptanalysis, with a specific emphasis on block and stream ciphers. I aim to explore and develop novel cryptanalytic techniques such as Differential Attacks, Linear Attacks, Cube Attacks, Differential Fault Attacks, Collision Attacks, Yoyo Attacks, and Biclique Attacks to uncover vulnerabilities in these cryptographic systems. By investigating the underlying algebraic structures of symmetric key ciphers, I seek to identify potential weaknesses that could be exploited by attackers. Understanding the algebraic properties of these ciphers is crucial for devising effective cryptanalysis strategies, improving the security of existing ciphers, and guiding the development of future encryption algorithms.
