摘　　要：针对电力企业中敏感数据保护和用户安全访问问题,提出一种在电网环境下的用户访问控制方案。当用户需要查询相关数据时,就必须与电力系统的内网服务器产生交互,从内网服务器获取需要的数据。在此过程中,恶意用户可能假冒合法用户的身份向服务器发出请求,非法获得数据。通过建立多授权机构,采用属性加密技术,对APP用户进行授权从而控制用户对数据的访问,防止恶意用户对电网系统造成安全威胁。通过对敏感数据进行加密处理,保证敏感数据的机密性。分析和评估结果表明,该方案具有较好的安全性,计算代价较低。For sensitive data protection and user security access issues in electric power enterprise,this paper proposes an access control scheme for user of electrified wire netting.When the user wants to query the data,he must interact with the network server in the power system,and obtain the required data from the internal network server.In this process,the malicious user may fake the legitimate user to make a request and obtains the data illegally.Users are authorized and controlled to access the data through building attribute authorities and using attribute-based encryption to prevent the malicious user from threating the power grid system.The scheme also encrypts the sensitive data and ensures the confidentiality of sensitive data.The results of analysis and evaluation show that the proposed scheme has better security and lower computing cost.
