Hierarchical power analysis attack for falsification detection cipher

The risk of IoT devices to be attacked by external networks has been reported. Therefore, falsification detection ciphers that can realize encryption and authentication simultaneously have attracted the attention of many researchers as a measure to prevent these attacks. Many studies have been reported on power analysis against AES. However, there are very few studies on power analysis against falsification detection ciphers. The present study proposes a method of power analysis against Minalpher, a falsification detection cipher. Experiments using an actual device prove the validity of the proposed method.
