In satellite communication systems, satellite power and processing capacities are limited, which means that storage and security are also constrained. Satellite communication channels are extremely vulnerable to hackers and external interference signals. Protecting satellite networks from illegal information access and use can be extremely challenging. In this paper, an architecture composed of satellite and ground equipment is developed that integrates communication network authentication and

In the proposed scheme, the communication, registration, authentication, and revocation of information are achieved through stages to improve communication security. The satellite forwards the collected information to a ground base station, which has a strong data processing capacity. The ground base station records all the key parameters in the distributed blockchain, and all malicious node certificates are removed from the system. To further enhance data transmission security, the key is transferred using an asymmetric encryption algorithm. To measure the robustness of using the proposed network architecture, under the same attack condition, an invulnerability analysis is performed. After conducting simulation experiments, the results show that the proposed scheme greatly improves communication security and protection.

According to satellite communication protocols, the use of space in satellite communications can be developed independently to enhance communication security. Recommendations have been proposed to further increase the unity and compatibility of communication protocols for space. A single security mechanism is insufficient to meet the security requirements for satellite communication services [2] . In this paper, blockchain technology is introduced to analyze the security of satellite communication networks in terms of access control, confidentiality, and security authentication. FIGURE 1.
