Power data signature aggregation method and system

Abstract

The invention discloses a power data signature aggregation method and system. The method comprises the following steps: randomly selecting a safety parameter by utilizing a control center, and inputting the safety parameter into an elliptic curve parameter generator to generate a system parameter; determining a control center private key, a control center public key corresponding to the control center private key, a convergence terminal private key, a convergence terminal public key corresponding to the convergence terminal private key, an edge terminal private key and an edge terminal public key corresponding to the edge terminal private key; when data is reported, after edge reporting information is preprocessed, determining a reporting information ciphertext, a temporary public key and a signature value according to a private key, and packaging the reporting information ciphertext, the temporary public key, the public key and the signature value into edge terminal signature information to be sent to superior equipment; after the superior equipment receives the signature information, aggregating the signature information to obtain aggregated information, and verifying the aggregated information.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a power data signature aggregation method and system. Background technique [0002] With the integration and application of Internet of Things, cloud computing, big data and other technologies in power systems, the Internet of Things in power has developed rapidly.
