Abstract

Over the past 20 years, side-channel analysis (SCA) on IC Chip has mainly taken place. However, recently, there has been an increasing number of issues of SCAs on the Internet of things (IoT) devices. As the IoT is directly applied to all things in our real life and post-security measures are impossible or involve high costs after the introduction, it is important to create a safe IoT environment. Thus, in this paper, we introduce the trends of SCAs on IoT devices. In particular, single-trace attacks that only use side-channel information are actively studied; it eliminates the need for information about the input and output values of cryptographic algorithms. This is a very powerful attack using only a single-trace and can be applied not only to public-key cryptography but also to post-quantum cryptography, which is actively being studied to counter the quantum computing era. Therefore, this paper suggests the urgency of developing countermeasures to this.
