                    摘   要:在跨域访问控制中,不同用户或应用程序可能根据各自的需求和权限,提出具有不同属性规格的访问
                    请求。传统的跨域访问控制方法无法有效处理这种差异化的属性规格,导致访问控制操作变得低效,且精度
                    有所降低。为此,提出了一种基于区块链技术的电网企业数据跨域访问控制方法。该方法首先构建以区块链
                    技术为基础的电网企业数据跨域访问控制逻辑架构,在该架构的支持下区块链模块对原始的访问申请进行预
                    处理,将访问请求信息转化为以属性集描述为基础的形式;然后根据访问请求信息的属性规格对电网企业数
                    据进行一次映射和二次映射处理,结合映射处理结果在电网企业数据库的标准属性表中确定请求域中涵盖的
                    属性集,为不同域的用户提供对应的数据,实现数据的跨域访问控制。试验结果表明,该方法的互操作性均值
                    始终处于较高水平,稳定在 0.95 左右,并且电网企业数据跨域访问控制准确率在 96%~98%,电网企业数据
                    跨域访问控制效果好。

                    Abstract:In cross-domain access control, different users or applications may submit access requests with varying
                    attribute specifications based on their respective needs and permissions. Traditional cross-domain access control
                    methods fail to effectively handle these differentiated attribute specifications, resulting in inefficient access control
                    operations  and  reduced  precision.Therefore,  this  paper  proposes  a  cross-domain  access  control  method  for  grid
                    enterprise data based on blockchain technology. It constructs a logical architecture for cross-domain access control
                    of  grid  enterprise  data  using  blockchain  technology.  Within  this  architecture,  blockchain  modules  preprocess
                    original access requests and transform access request information into a form based on attribute sets. Based on the
                    attribute specifications of the access request information, the grid enterprise data undergoes primary and secondary
                    mapping processes. The results of these mapping processes are combined to determine the attribute sets covered
                    in the standard attribute table of the grid enterprise database, thereby providing corresponding data to users from
                    different  domains  and  achieving  data  cross-domain  access  control.  Experimental  results  demonstrate  that  the
                    interoperability mean value of this method consistently remains at a high level, stabilizing around 0.95. Moreover,
                    the  accuracy  of  cross-domain  access  control  of  grid  enterprise  data  ranges  between  96%  and  98%,  indicating
                    effective performance.
