Power analysis attack for a fast authenticated encryption MORUS

Since Internet of Things (IoT) is widely used, IoT security is very important. Therefore, authenticated encryptions, which realize data encryption and the authentication between devices simultaneously, have been attracted attention. MORUS is one of the most popular authenticated encryptions. Regarding hardware security, the threat of power analysis attack is pointed out. However, power analysis attack for MORUS has not been reported. Therefore, this study proposes a new power analysis attack for MORUS. Experiments using a field programmable gate array prove the validity of the proposed method.
