The 84th In Silico Megabank Research Seminar , Seminar of Toshiba-Tohoku University Joint Research on Quantum Cryptography Communication, and Security Seminar will be held together as below.

・Date/Time: December 14(Thursday) 6:00‐7:30 pm 
・Venue: Conference Room(3rd Floor), Tohoku Medical Megabank Building

［Program］
1. Explanation on the progress of the joint research (Masao Nagasaki, Tohoku University)

2. ・Lecturer: Masahide Sasaki（National Institute of Information and Communications Technology）
・Title: Super long-term secure secret sharing storage system using quantum key distribution technology 
・Abstract: Genome information and life-critical medical information of individuals are relevant to multiple families’ ancestry and lineage as well as multiple generations. If such information is leaked, it can cause irredeemable situations. Therefore, it is essential to guarantee super long-term confidentiality (information is not exposed to others) and integrity (data is not altered or falsified) of such information over a century. However, it is not impossible to secure super long-term confidentiality and integrity with the current coding alone since it cannot completely prevent future safety to be compromised. On the other hand, well-combined protocols of quantum key distribution technology and secret sharing can actualize a secret sharing storage system that doesn’t allow any computer machines to decode and that can restore the original data correctly even if servers of some areas are damaged due to disasters or similar events. At National Institute of Information and Communications Technology (NICT), research and development of super long-term secure secret sharing storage system are currently carried out with cooperation of medical institutions. In this seminar, the mechanism of quantum key distribution technology is explained and the overview of secure secret sharing storage system, the progress status of the project, and future prospects are discussed.

3. ・Lecturer: Hideaki Sato（Toshiba Corporate Research & Development Center）
・Title: Quantum Cryptography Technology at Toshiba and Overview of the Joint Research with Tohoku University 
・Abstract: Quantum cryptography communication is a cryptography communication system that actualizes the ultimate safety of data, and it enables realization of cryptography communication where data can never be decoded. Toshiba is currently taking initiatives to make a practical use of quantum cryptography technology developed by Cambridge Research Laboratory of Toshiba Research Europe Ltd. headquartered in England. Also, Toshiba has been conducting a joint research with Tohoku University on genomic data transmission since 2015. In this seminar, overview of progress of the joint research and current status of research and development of cutting-edge quantum cryptography communication device will be explained, and the future vision of systems utilizing quantum cryptography communication will be discussed.

4. Importance of security ( Takako Takai, Tohoku university)

5. Closing remarks (Fuji Nagami, Tohoku University)
