The secure network communication is the key technology for IoT (Internet of Things). IoT devices are required to have high security and low power consumption. Cryptographic circuits and secure key storage are implemented on IoT devices in order to protect secret information. 
Recommended cryptographic algorithms are computationally secure, however, the attacker reveal secret information by analyzing the side-channel information such as power consumption and electro-magnetic field. Furthermore, the attacker could clone security LSIs by analyzing physical information. In our laboratory, we are researching tamper-resistant LSI which protect secret information, and Physically Unclonable Function for anti-cloning. In addition, we are studying in-vehicle security technology such as AI-assisted intrusion detection system and sensor fusion system.
