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 mathematical tools such as complexity theory and information theory. We aim to consider every angle of security sysmtes in collaboration with Sakiyama-Miyahara Lab., Li Lab., and Sugawara Lab., which are laboratries that mainly focus on hardware security.
