Although internet of things technology is widely used in various fields, internet of things has several issues such as energy efficiency and authentication for security. The energy harvesting technology, which harvests various energy (eg, sunlight, vibration, electromagnetic wave, and so on), and converts them to electric power, has attracted attention for the solving method for the first problem. Moreover, the physical unclonable function, which uses variances of semiconductor manufacturing variations for authentication, has attracted attention for the solving method for the other problem. This study proposes a new authentication method for energy harvester. The proposed method utilizes the difference in power generation time due to manufacturing variations for the device authentication. In addition, the proposed method can be realized in very low cost because it does not require a dedicated physical unclonable function circuit. Several experiments using an actual energy harvester verify the validity of the proposed method.

利用能量采集器中发电时间变化的认证方法及其评估

尽管物联网技术已广泛应用于各个领域,但物联网仍存在一些问题,例如能效和安全认证。能量收集技术收集各种能量(例如,太阳光,振动,电磁波等)并将其转换为电能,这已成为解决第一个问题的方法的关注点。此外,使用半导体制造偏差的变化进行认证的物理不可克隆的功能引起了对另一问题的解决方法的关注。这项研究提出了一种新的能量收集器认证方法。所提出的方法利用由于制造差异而导致的发电时间的差异来进行设备认证。此外,由于该方法不需要专用的物理不可克隆功能电路,因此可以以非常低的成本实现。使用实际的能量收集器进行的一些实验证明了该方法的有效性。
