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. Keywords: Public-Key Cryptography, Post-Quantum Cryptography, Side-Channel
