With the gradual deployment of the spacebased wireless network, security risks in the data communication between satellites and even the internal structure of a satellite become extremely important. In this article, we use the satellite’s internal communications security as an example to illustrate the space network security threats. We first provide a summary of the security requirements of space-based wireless networks. Then three typical attack approaches for satellite platforms based on MIL-STD-1553B bus are described. Subsequently, we present some attack simulation results and suggest some protective mechanisms.
