Power IoT Data Interaction System Based on Edge IoT Agent and Identification & Resolution

Internet of Things (IoT) technology is widely used in power grid systems. The enormous scale of IoT power needs to be properly engineered to ensure efficient and secure data collection, storage, and processing. An efficient and security-enhanced data interaction system based on edge IoT agent and Identification & Resolution is proposed. Terminal devices in the system need to register their information in the IoT management center in order to obtain the identity and key of the terminal devices. In the key ex-change protocol, the integration of identity and timestamps for sig-natures with the real needs of the agent and terminal devices. Once the key negotiation is complete, the terminal device collects the data and transmits it encrypted. The data is decrypted by the IoT agent and then securely stored using an attribute-based encryption protocol, ensuring efficient and secure data querying capabil-ities.
