Outline of Final Research Achievements |
The IoT (Internet of Things) is now one of the most significant infrastructure and has to be secure against malicious accesses. In the CBAC (Capability-Based Access Control) model adopted to the IoT, device owners issue subjects capability tokens, i.e. a set of access rights on objects in devices. Objects are data resource manipulated by subjects. Data are exchanged among subjects and objects through manipulating objects. Here, even if subjects attempt to manipulate objects in accordance with the capability tokens issued, the subjects can get data which the subjects are not authorized to get, i.e. illegal information flow occurs. In this research, we implemented a protocol to prevent illegal information flow from occurring. In addition, we improved the protocol to reduce the electric energy consumption of devices supporting the protocol. In the evaluation, the electric energy consumption in the improved protocol can be reduced compared with the conventional protocol.
