Khandaker Md. Al-Amin
Cybersecurity Engineer
I am a Cybersecurity Engineer at ITK Engineering GmbH, focusing on cryptographic solutions and secure system design. Previously, I worked as a Research Engineer at EAGLYS Inc., where I developed privacy-preserving machine learning solutions using homomorphic encryption and secure multiparty computation.
I hold a Ph.D. in Cryptography from Okayama University, where I specialized in elliptic curve pairing-based cryptography and its applications for IoT security. My research was supported by the Japan Government Scholarship (MEXT).

Selected Publications
An Improvement of Scalar Multiplication by Skew Frobenius Map with Multi-Scalar Multiplication for KSS Curve
Scalar multiplication over higher degree rational point groups is often regarded as the bottleneck for faster pairing based cryptography. This paper presents a skew Frobenius mapping technique in the sub-field isomorphic sextic twisted curve of KSS pairing friendly curve.
