A method for secure sharing of multi-source data of smart energy system based on blockchain technology

Conventional multi-source data security sharing methods in smart energy systems mainly use ABE (attribute-based encryption) to encrypt attribute bases to generate access keys, which are susceptible to cloud storage single-point failures, resulting in poor sharing evaluation indicators. Therefore, this paper proposes a secure sharing method based on blockchain technology for multi-source data in smart energy systems. A multisource data security sharing center is generated, and blockchain technology is used to generate a multi-source data anonymous sharing algorithm for smart energy systems, thus achieving multisource data security sharing. Experimental results show that the designed smart energy system blockchain multi-source data security sharing method has better sharing effects, higher sharing indicators, reliability, and certain application values. It has made a certain contribution to promoting the transformation of energy structure and realizing the information management of smart energy.
