センサシステムと秘密分散技術（電子割符）による安全安心な社会基盤システム

抄録

In this paper we describe a secret sharing technology (e-Tally), which is a secure scheme, where we show how to make the e-Tallies and how secure they are. This technique enables the construction of the secure social infrastructure to protect the data from the disaster or hacker and to prevent the sensitive personal data from leakage. This secure social infrastructure also can be used to construct secure Internet of Things (IoT) networks by connecting to the sensor system of IoT networks.
