About Me

I’m a researcher of NTT Secure Platform Laboratories, NTT Corporation, Japan from 2012.
I received my Ph.D from Kobe University in March 2017 (supervisor : Masakatu Morii).
The title of my Ph.D Thesis is “Integral Cryptanalysis against Symmetric-Key Cryptosystems.”
My research area is cryptography. Especially, the design and analysis of the symmetric-key cryptography.

Our paper entitled “Cryptanalysis of AES-PRF and Its Dual” was accepted at ToSC 2018 (FSE 2019).
Our paper entitled “Fast Correlation Attack Revisited –Cryptanalysis on Full Grain-128a, Grain-128, and Grain-v1” was accepted at CRYPTO 2018.
The paper will be accessible sooner.
Our paper entitled “Improved Division Property Based Cube Attacks Exploiting Algebraic Properties of Superpoly” was accepted at CRYPTO 2018.
You can access the full version in the ePrint.
The full version of our paper “Cube Attacks on Non-Blackbox Polynomials Based on Division Property” publised at CRYPTO2017 was accepted at IEEE Trans. on Computers.
I joined a workshop: The Challenge of Lightweight Cryptanalysis, which was held at Bar-Ilan University in Israel.
I gave a talk entitled “Fast Correlation Attack on Grain-type (Lightweight) Stream Ciphers”
The full version of our paper “Nonlinear Invariant Attack” published at Asiacrypt2016 was accepted at Journal of Cryptology.
