Abstract(in English) As a fellow receiving a prize commemorative lecture, I look back on 36-year research and education experiences on modern cryptography after starting a study in March of 1983. I will pick up topics that seem to be able to be interested by everybody, specifically 1. A proposed method (FEAL cipher) by our group be attacked, 2. Attacking on the wide spread method (MD5 APOP certification method), and 3. In order to keep study activities at the world top-level etc. I hope you will enjoy them!
