Fog computing-based power data privacy protection aggregation method and system

The invention provides a power data privacy protection aggregation method and system for fog computing, and relates to the technical field of privacy, and the method comprises the steps: an intelligent electric meter and an edge node generate a hash function based on the ID of the intelligent electric meter and the edge node, and send the ID of the intelligent electric meter and the corresponding hash function as a registration request to a key distribution center through a secure channel; the intelligent electric meter collects electricity utilization information of a user according to the received demand of the service center, encrypts the electricity utilization information by introducing a differential privacy mechanism into a generative adversarial network, and sends the encrypted electricity utilization information to the edge node; the edge node verifies the signature validity of the encrypted power consumption information, under the condition that the signature is valid, the verified and encrypted pow
