摘要
我国电网采购交易平台具有交易金额巨大、供应商数量众多、流程管控要求严格的特点.本文提出的电网采购交易数据平台,基于Hyperledger Fabric技术,结合数据库层面的数据哈希计算、数据指纹提取、权限访问控制、数据快速读取等方法,实现了覆盖采购交易数据全生命周期的多级数据防护与数据防篡改,可以有效管控由于采购交易平台各主体间的信息不对称可能导致的信任危机.最后,通过对该策略原型系统的防护性能进行试验分析,验证了该原型系统的可行性.
China’s transaction platform for grid procurement features a huge transaction amount,a large number of suppliers,and strict process control requirements.The transaction data platform for grid procurement proposed in this study is based on Hyperledger Fabric technology and methods at the database level,such as hash calculation of data,data fingerprint extraction,access control,and fast data reading.It can achieve multi-level data protection and data tamperproofing through the entire life cycle of procurement transaction data and can effectively control the trust crisis that may be caused by the asymmetry of information among subjects of the procurement transaction platform.Finally,the feasibility of the prototype system for the proposed strategy is verified by the experimental analysis of the protection performance of the system.
