• 論文抄録 / 内容記述: As IoT has increasingly evolved in recent years, it has become more important to ensure security on IoT devices. Many of such devices are under the threat of side-channel attacks. To protect from the threat, the cryptographic implementation which offers security against side-channel attacks is important. However, such cryptographic implementations require a large number of clock cycles to execute and can only be resistant to certain types of side-channel attacks. In this paper, we aim to provide secure cryptographic implementation against side-channel attacks using space-hard ciphers which are secure in the white-box setting. Specifically, we first show that using a space-hard cipher is secure against side-channel attacks. After that, we propose a new family of space-hard ciphers dubbed Cubicle. This cipher has opted for the implementation on processors of ARM Cortex-M which are widely used for IoT devices. We show that Cubicle is secure against various attacks including side-channel attacks and the performance is about 4 to 5 times higher than one of the existing space-hard cipher, SPACE in devices powered by the Cortex-M processor.
