摘　　要：为了解决现有系统在用户解除访问权限后存在的入侵风险问题,提出了身份属性分类下电网设备故障数据访问控制方法。设计基于身份属性分类安全访问平台,采用基于权重的合成方法实现多个属性的身份验证。分析客户端和服务器之间的密钥传递关系,计算不同分类结果的私钥和密钥,结合AES算法,获取待访问数据密文,并输入访问结构树,设计数据访问控制过程。由实验结果可知,应用所提方法后数据入侵率由0.1降到0.06。所提方法能够加密、解密全部数据,具有良好的控制鲁棒性和访问安全性。In order to address the intrusion risk issue in existing systems after users have revoked access permissions,a method for accessing power grid equipment fault data under identity attribute classification is proposed.Design a secure access platform based on identity attribute classification,and use a weight based synthesis method to achieve authentication of multiple attributes.Analyze the key transfer relationship between the client and server,calculate the private key and key for different classification results,combine with the AES algorithm,obtain the ciphertext of the data to be accessed,input it into the access structure tree,and design the data access control process.According to the experimental results,the data intrusion rate of the proposed method has decreased from 0.1 to 0.06 after application.The proposed method can encrypt and decrypt all data,with good control robustness and access security.
