Research on Zero-Trust Based Network Security Protection for Power Internet of Things

For the new characteristics of power Internet of Things (IoT), the traditional perimeter-based security model could not satisfy the network security requirements of the power IoT. However, zero trust security model was proposed in the past decades to meet new security challenges of networks. In this paper, the technical characteristics of zero trust security architecture are studied and analyzed. The security protection technology of the power IoT based on zero trust security architecture is proposed. Through identity authentication, application agent, data encryption and other security protection technologies, a fine-grained security control of access mechanism is designed. Our propositions provide a solution and technical exploration for future security protection of the power IoT to help power enterprises build more secure network security.
