摘　　要：由于网络数据访问通常涉及多个节点、用户和数据之间的复杂交互,同时还要满足合法用户的访问需求,导致对其控制存在控制误判率高的问题,无法确保网络数据安全。为此,研究一种网络数据访问自动控制方法。设计一种用户行为信任评估算法,评估数据访问用户行为信任度;利用属性加密技术,加解密处理网络数据属性;根据访问自动控制权限裁决结果,判定用户是否具备访问权限,完成网络数据访问控制。对比实验证明,采用所提控制方法误判率得到有效控制,仅为1.36%,控制精度更高,对于促进网络中数据的安全性提升具有极大帮助。Because network data access usually involves complex interactions between multiple nodes,users and data,and also needs to meet the access requirements of legitimate users,it leads to the problem of high control misjudgment rate and cannot ensure the security of network data.Therefore,an automatic control method of network data access is studied.A user behavior trust evaluation algorithm is designed to evaluate the user behavior trust of data access.Attribute encryption technology is used to en-crypt and decrypt network data attributes.According to the result of access automatic control permission,determine whether the user has access permission and complete network data access control.Comparative experiments show that the error rate of the pro-posed control method can be effectively controlled,only 1.36%,and the control accuracy is higher,which is of great help to pro-mote the security of data in the network.
