Protocol-based Security Mechanism for Satellite Networks

A completely linked world with sixth generation (6G) networks is anticipated as a result of the convergence of terrestrial radio and satellite communications. Satellite physical restrictions on the amount of available power and space results in low computing power, constrained storage capacity, and compromised security. Data may therefore be susceptible to modification and contamination by others. Security concerns have arisen as satellite communications have become increasingly important to international communications networks. In satellite networks, it can be difficult to efficiently use storage and secure information access. With regard to satellite communication networks, this proposal suggests a privacy and authentication system based on QKD protocol. This is accomplished by implementing a wireless, heterogeneous network connectivity architecture that combines both open-source and commercially available devices. Registration, authentication, and revocation are the three processes that enable communication. Satellites transmit the gathered data to ground stations, which then record all significant parameters on the system's decentralized blockchain. All certificates from malicious nodes are removed from the blockchain by ground stations. It has been suggested for use with 6G networks in the future and beyond the Internet of Things, self-driving cars, and other quickly developing applications. Excellent security levels are provided by satellite-based blockchain and QKD systems.
