| Title | Access Control Architecture for Smart City IoT Platform |

| Abstract | Smart city is a concept that leverages IoT (Internet of Things) for efficient operations. Many use cases have been proposed, for example efficient garbage collection, smart traffic control, improvement of safety and security of cities, and disaster recovery. To provide better services, information from several domains need to be integrated. For example, in a case of a disaster recovery from an earthquake, a traffic control system and a medical emergency system should collaboratively work for efficient ambulance delivery to patients. However, such inter-domain collaboration imposes security risks regarding confidentiality. Especially, information leakage of privacy-sensitive data such as medical information must be prevented. Another risk is integrity of the information. An IoT platform needs to ensure that only privileged persons can update the information. Unfortunately, it is not clear what type of the access control is required in smart city. In this paper, we analyze use cases of smart city and clarify requirements of access control for the smart city IoT platform. We also examine attribute-based access control to satisfy the requirements. We further investigate requirements of internal access control of smart city IoT platform, and proposes an access control mechanism based on information flow history to control information flow between components of the platform. |
