Abstract: With the emergence of advanced communication technologies such as high-throughput satellites, the integration of power satellite and smart grid has become an inevitable trend, and its related security certification has become the focus of research. However, the existing authentication schemes are mainly studied under the isomorphic architecture focusing on ensuring the authenticity verification of entities. Therefore, a heterogeneous authentication scheme for smart grid based on power satellite is introduced. The proposed scheme realizes the authenticity verification of each communication entity in a heterogeneous environment, and provides a validity verification method for terminals. Security analysis confirms the correctness and security of the scheme, and performance analysis shows that the proposed scheme effectively reduce the time cost of authentication phase than the existing schemes.
