泛在电力物联网可信安全接入方案

为全面提高全业务泛在电力物联网安全综合防御能力，解决目前全业务泛在电力物联网安全防护指导和终端认证机制的缺失和不足，本文提出一种泛在电力物联网可信安全接入方案。首先给电力物联网终端层设备确定一个唯一标识的指纹信息；然后结合该指纹信息，采用身份标识密码技术实现终端层设备的接入认证，阻断非法终端的接入；最后设计合法终端的身份信息安全传递机制，根据身份信息对合法终端的异常行为进行溯源。

Trusted Secure Access Scheme of Ubiquitous Power IoT

In order to comprehensively improve the comprehensive security defense capability of all-service ubiquitous power Internet of Things(IoT), and solve the lack and deficiency of the security protection guidance and terminal authentication mechanism of all-service ubiquitous power IoT, this  paper proposes a trusted secure access scheme of ubiquitous power IoT. Firstly, a unique fingerprint information is determined for the power IoT terminal layer equipment. Then, combined with the fingerprint information, the identification and password technology is used to realize the access authentication of terminal layer equipment and block the access of illegal terminals. Finally, the security transfer mechanism of legal terminal identity information is designed to trace the abnormal behavior of legal terminal according to the identity information.
