Abstract:

The rapid development of the IoT and the ubiquitous connection and intelligent interaction of a large number of heterogeneous terminals have made the network boundaries of the power IoT blurred, and the network structure is more complex, and the security risk points and exposed areas have increased significantly. This paper abandoned the traditional security mechanism of connection before authentication and put forward a kind of security protection scheme for the power IoT with the zero trust security mechanism, while applying the SPA to effectively solve the problems of identity authentication, resource hiding, and access control of power IoT terminals. Finally, the scheme was compared and analyzed from security and communication performance. The results show that the proposed scheme can effectively resist multiple types of network attacks, and save computing and communication resources, and effectively solve the problems of identify authentication existing in the power IoT.

Key words: power IoT, SDP, SPA, secure access, identity authentication
