The Security for Power Internet of Things: Framework, Policies and Countermeasures

With many applications of internet of things (IoT) technology in smart grid, the power internet of things (PIoT) faces new issues in security, especially in sensing applications. This paper illustrates perspective of the PIoT and its security, and gives the security framework, security policies and appropriate countermeasures. Since the PIoT is a huge complex cyber-physical network, the study on the security of PIoT, especially the influence of the perception layer, is of importance from both the architecture and measures. Considering about the huge numbers of new technologies and intelligent devices, we propose a global perspective security framework from perception layer to application layer. Meanwhile, we also give the security policies and measures. Some of researches in this paper have been adopted in some projects, the results show that the design is effective.
