摘要
随着信息化的大力发展及广泛应用,传统中心化电力交易与数据存储方式的缺点逐渐显现出来。基于去中心化的区块链技术,提出分布式电力交易方法。此外,为了实现电力数据的安全存储与访问控制,设计了一个多中心属性加密方案,各联盟节点分别管理不同属性,同时联合对用户进行密钥生成及授权,从而达到去中心环境下的电力数据细粒度访问控制机制。
With the rapid development and wide application of information technology,the disadvantage of the traditional grid decentralized transaction and data storage have gradually emerged.Based on the decentralized blockchain technology,we propose a distributed power trading method.In addition,in order to realize the secure storage and access control of power data,we designed a multi-authority attributed-based encryption scheme.Each alliance node managed different attributes respectively,and they jointly generated and authorized key to users,thus achieving the fine-grained access control mechanism of grid data in a decentralized environment.
