Abstract

The invention provides a smart power grid privacy protection and electricity stealing detection method based on a block chain. The method is reasonable in design, high in practicability, safe and efficient. The method comprises the following steps: 1) initializing a system; 2) requesting for data aggregation; 3) replying a data aggregation request; 4) generating a user report; 5) aggregating the security data; 6) data aggregation recovery; and 7) the control center CC detects and analyzes the power consumption data so as to detect the electricity stealing behavior of the user. According to the method, the intelligent electric meter with limited resources in practical application can be met, privacy protection and integrity protection in intelligent power grid communication are achieved, safe, efficient and traceable user group data are utilized, electricity consumption data are analyzed to detect the electricity consumption behavior of a user, the electricity stealing behavior is found, and a result is safely transmitted.

Description

technical field [0001] The invention relates to a block chain-based smart grid privacy protection and electricity theft detection method. Background technique [0002] In order to protect the privacy of users, many power grid privacy protection schemes use the semantically secure Paillier encryption algorithm to encrypt the ciphertext. However, the Paillier algorithm has a large amount of calculation, which increases the calculation burden of smart meters, and is not suitable for resource-restricted applications. limited smart meters. Although some solutions for privacy-preserving data aggregation in smart grids have been proposed, most of the existing works are based on computational overhead operations, and these methods are not suitable for smart meters with limited computing power and resource constraints. [0003] However, the above solutions all have the problem that it is difficult to find an aggregator that all users trust, and there are great challenges in the avai...
