Secure Computation in the Cloud

Prof. Hayato Yamana
Waseda University, Japan

By Prof. Hayato Yamana, Waseda University, Japan.

In this talk, I will pick up a privacy issue that effects to our society followed by introducing secure computation using fully homomorphic encryption (FHE) in cloud computing. IDC reported that “At least 40 percent of big data requires some level of security, from privacy protection to full-encryption.” Especially, medical information including images should be kept strictly secured. To handle such sensitive data, FHE is one of the key technology to realize secure computation, i.e., handling all data with encryption throughout the data life cycle. I will introduce the basic technologies used in FHE and its remained problems to be solved.


Hayato Yamana received his Dr. Eng. degree at Waseda University, Japan in 1993. He began his career at the Electrotechnical Laboratory (ETL) of the former Ministry of International Trade and Industry (MITI), and was seconded to MITI’s Machinery and Information Industries Bureau for a year in 1996. He was subsequently appointed Associate Professor of Computer Science at Waseda University in 2000, and has been a professor since 2005. From 2003 to 2004, he was IEEE Computer Society Japan Chapter Chair. From 2015 to 2017, he was director of IPSJ (Information Processing Society of Japan) and vice chairman of information and communication society of IEICE (the institute of electronics, information and communication engineers). From 2018, he is Board of Governor of IEEE Computer Society. His research area is big data analysis. Currently, his group engages in Japanese government funded project called “Secure Data Sharing and Distribution Platform for Integrated Big Data Utilization – Handling all data with encryption.” For more information, please refer to
