Evaluation of Energy Harvesting Technique for Security Module

Abstract

In internet of things (IoT), devices connect to external network in order to communicate data each other, and the improvement of human life is expected. However, IoT devices have problems to be solved, including design of low power and security such as authentication of devices. To overcome these problems, energy harvesting and physical unclonable function (PUF) have attracted attention. Actually, we have proposed a PUF using energy harvesting called energy harvesting PUF. However, since input of the energy harvesting PUF is fixed, available information for authentication is limited. Therefore, this study evaluates the energy harvesting PUF by increasing input value. Experiments using an actual energy harvester also showed the validity of the energy harvesting PUF.
