The Internet of Things (IoT) is a concept that creates new value by connecting various devices that have traditionally not been connected to networks such as the Internet. IoT is regarded as a potential source of innovation by governments and companies around the world, with many IoT services being developed.
However, devices that have never been connected to a network have often been left unsecured. In fact, IoT security has become an urgent issue because of cyber-attacks on IoT devices. Typically, the data center which receives IoT device data is a physically secure facility. On the other hand, the IoT devices themselves are exposed to a very "weak" physical security environment. If the security of the IoT devices is insufficient, it becomes easy for an attacker to retrieve and read the internal data for the IoT services.
To solve these problems, we focus on cryptography and hardware security. By using encryption technology and establishing secure communications, the IoT devices can be protected from these threats. Hardware security technology can also prevent attacks that steal the core cryptographic "keys" from devices.
Independent of IoT, the overall goal of security technology is to ensure the reliability, safety, and security of systems and services. Intelligent Systems Laboratory describes these concepts as "trust". In order to establish "trust” in IoT, Intelligent Systems Laboratory continues to research cryptography and hardware security.
