摘要
由于缺乏对跨域电力营销数据认证节点的有效过滤,导致认证安全性无法达到理想效果。对此,该研究设计新的跨域电力营销数据安全访问多级身份认证模型。通过计算节点权值结合不同节点的正贡献值,抽取可信度较高的认证节点。基于划分身份认证操作安全等级,并为不同等级的认证操作生成不同的复杂密钥,结合共识机制构建多级身份认证模型。在实验中,对提出的方法完成认证安全性的检验。最终的测试结果表明,采用提出的方法完成身份认证时,认证节点被攻击的概率较小,具备较高的认证安全性。
Due to the lack of effective filtering of crossdomain power marketing data authentication nodes,the authentication security can not achieve the ideal effect.In this paper,a new multi-level authentication model for secure access to cross domain power marketing data is designed.The node weights are calculated,and the positive contribution values of different nodes are combined to extract the authentication nodes with high reliability.Based on the classification of security levels of authentication operations and the genera-tion of different complex keys for different levels of authentication operations,a multi-level authentication model is built by combining the consensus mechanism.In the experiment,the security of the pro posed method is verified.The final test results show that the probability of authentication node is small to be attacked and has higher authentication security when the proposed method is used to complete identity authentication.
