Energy transaction data sharing system and method based on cloud chain fusion

The invention discloses an energy transaction data sharing system and method based on cloud chain fusion, and the system comprises a data sharer, a data acquirer, a cloud service provider and a block chain, the data sharer is mainly responsible for collecting system operation information, carrying out the classification and encryption of the information, and transmitting the information to the block chain and the cloud service provider. The data acquirer mainly refers to a node having an acquisition demand for shared data in the system, the cloud service provider performs credible verification and encrypted storage on the shared data uploaded by the data sharer, and the block chain stores key information and a sharing result of the shared data. The method comprises the steps of initialization parameter setting, information encryption, index generation, trap door generation, shared data search and data verification. According to the energy internet data sharing system under cloud chain fusion, the storage comp
