摘要
电力卫星物联网刚刚起步,对于安全接入的保障还有待提高。文章以标识公钥为基础,结合电力卫星物联网的工作特点,提出了一种基于标志公钥的电力卫星物联网边缘安全接入机制。采用轻量级标识密钥体系来实现电力卫星物联网的安全接入与安全防护,该种物联网安全接入实现机制具有去中心化,无需证书颁发机构证书认证,且低功耗,适用于无线低带宽网络的特点,可以有效保障各类终端设备的合法性,防止设备的非法接入,且可以加强电力卫星物联网的安全访问控制和数据的安全性,使基于北斗卫星的电力通信安全性得到了有力的提升。
The power satellite Internet of Things has just started,and the security guarantee for security access still needs to be improved.Based on the identity public key and combined with the working characteristics of the ubiquitous power satellite Internet of Things,this paper proposes an IPK-based edge security access mechanism for the power satellite Internet of Things.Using lightweight logo key system to implement the power satellite Internet security access and safety protection,the Internet of Things security access mechanism implementation is decentralized,without the CA certificate authentication,low power consumption,suitable for the characteristics of low bandwidth wireless network,can effectively guarantee the legitimacy of all kinds of terminal equipment,to prevent illegal access of the equipment.The proposed access mechanism can strengthen the security access control and data security of the power satellite Internet of Things,and the power communication security based on Beidou satellite has been effectively improved.
