In order to ensure the privacy protection and data security in the current power supply chain data sharing mechanism, inspired by the ability of attribute-based encryption technology to effectively realize the secure sharing and access control of data on the cloud. Proposes an anti-counterfeiting sharing model based on attribute-based encryption for the Blockchain of the Electric Power Material Alliance. First, in the private key generation phase, the data user entrusts multiple nodes to participate in the joint calculation and store part of the private key, while other data users cannot obtain the complete key, thereby improving the efficiency of private key generation; Finally, by constructing a shared chain with on-chain and off-chain collaborative computing and storage functions, the effective integration of attribute-based encryption and blockchain systems is realized. Security analysis and experimental simulation results show that the proposed model has certain optimizations in terms of key generation calculation efficiency and actual business scenarios, and meets the needs of power supply and application.
