摘要
针对电力工程质量管理中见证取样和检测数据在建设单位和施工单位等多部门之间共享过程中,存在不可信、难溯源和存储效率低等问题,文章提出了一种电力工程检测数据共享方案,方案中各参与单位组成联盟区块链,工程检测数据被加密后进行链上和链下混合存储,采用密文策略属性加密能有效地实现对密文数据跨单位安全共享,采用元数据与属性加密结合能够解决存储效率低的问题,也能解决溯源和隐私保护同时兼顾的矛盾。
Aiming at the problems of unreliability,difficult traceability and low storage efficiency in the sharing process of witness sampling and detecting data among the units of the proprietors and constructors in power engineering quality management,this paper proposes a power engineering detecting data sharing scheme,In the scheme,all participating units form an alliance blockchain,and the engineering detection data are encrypted for hybrid storage on and off the chain.Ciphertext-policy attribute-based encryption(CP-ABE)is used to realize the safe sharing of ciphertext data across units effectively.The combination of metadata and attribute encryption can solve the problem of low storage efficiency and the contradiction between traceability and privacy protection.
