Professor Miyaji, Security and Networks Area, received the Best Paper Award at the 14th Asia Joint Conference on Information Security (AsiaJCIS2019)

Professor Atsuko Miyaji, Security and Networks Area, has received the Best Paper Award at the 14th Asia Joint Conference on Information Security (AsiaJCIS2019).
This conference was held in Kobe, Japan on August 1 through 2, 2019. The focus of this conference is on the technical and practical aspects of the security applications.
They proposed a paper "Secure Online-Efficient Interval Test Based on Empty-Set Check" and have achieved a secure online-efficient interval test by adopting the notion of online and offline phases.

■Title
Secure Online-Efficient Interval Test Based on Empty-Set Check

■Abstract
In the age of information and communications technology (ICT), not only collecting data but also using such data is provided in various services. It is necessary to ensure data privacy in such services while providing efficient computation and communication complexity.
In this paper, we propose the first interval test designed according to the notion of online and offline phases by executing our new empty-set check.
Our protocol is proved to ensure both server and client privacy. Furthermore, neither the computational complexity of a client in the online phase nor the communicational complexity from a server to a client depends on the size of the set. As a result, even in a practical situation in which one server receives requests from numerous clients, the waiting time for a client to obtain the result of an interval test can be minimized.

■Comment in receiving a prize
It is a great honor to received the Best Paper Award from the 14th Asia Joint Conference on Information Security (AsiaJCIS 2019).
