Abstract (in Japanese) (See Japanese page) 
(in English) Side-channel attacks utilize side-channel information such as power consumption in addition to plaintext and ciphertext to illegally obtain secret information from cryptographic devices.
Due to the proliferation of IoT devices, side-channel attacks have become increasingly serious threats to cryptographic devices.
The key technique to succeed in side-channel attacks is to reduce the noise of the acquired side-channel information.
Autoencoder, a machine learning technique, is often used for noise reduction
and has already been applied to a side-channel attack scenario in previous research.
However, it could only be available for a limited type of implementation.
To address this issue, we propose a generalized autoencoder that can be applied to various scenarios.
To evaluate the effectiveness of the proposed method, we conducted an attack combining the proposed noise reduction method with a conventional CPA to our obtained power traces.
The experimental results show that the proposed attack can successfully recover the secret key with 50% fewer power traces than the low-pass filter-based noise reduction method.
