Data Security & Privacy Protection in IoT MGC Systems
Robert Huijie Deng · 2023
Many IoT and cyber-physical systems follow the MGC (eMbedded-Gateway-Cloud) architecture. In this architecture, embedded devices equipped with sensors send measurement data to a gateway which aggregates the data into appropriate records and upload them to the cloud for data access and analytics. An example application of the MGC architecture is infrastructure video monitoring, in which drones and robots with mounted cameras patrol physical operational environments for on-site monitoring, defeats inspection, etc, and videos are encrypted at a gateway and then uploaded to cloud for authorized access by various stake holders. In this talk, we will discuss the various data security and privacy issues in the infrastructure video monitoring system (and MGC architecture in general) and present a data security and privacy platform which supports flexible access control of encrypted data based on users’ attributes and time of access and supports multiuser-to-multiuser encrypted keyword search over encrypted data.
