Theoretical Approaches to Cryptography

Iwamoto-Watanabe Laboratory (IWL) is a research laboratory in Graduate School of Informatics and Engineering, the University of Electro-Communications (UEC). We design cryptographic algorithms and provide theoretical analyses of current cryptographic protocols by using mathematical tools such as complexity theory and information theory. We aim to consider every angle of security systems in collaboration with Sakiyama–Li–Miyahara Lab., Sugawara Lab., and Wang Lab., which are laboratories that mainly focus on hardware security.

We joined the project JST CREST “TRACE for IoT” in October 2023 as Advanced Cryptography Group, and also the project JST K Program “Advanced PQC” in April 2025.
