Abstract (in Japanese) (See Japanese page) 
(in English) The lightweight block cipher Midori has been proposed as a cryptographic algorithm for low-power operation, which is important as a security measure for IoT devices with power supply issues. For IoT devices that require real-time performance as well as low-power operation, a low-latency hardware implementation is suitable. On the other hand, some lightweight cryptography is vulnerable to side-channel attacks, and tamper-resistance verification is very important. Also, a low-latency implementation of Midori128 with a block length of 128 bits has not been reported to be tamper-resistant to a power analysis attack, which is one of the side-channel attacks. Therefore, this study proposes a power analysis attack method for Midori128, and demonstrate that power analysis information occurs in Midori128.
