The development of global communication networks depends on satellite communication. Due to its lower stability and reach, satellite communication networks have garnered a lot of attention recently as a means of reducing the limitations of terrestrial networks. Numerous inconveniences exist, including inadequate storage space, security, and data processing capacity. Illegal entry turned out to be the difficult one. Satellite physical limitations in terms of available power and area result in limited data processing capability, storage and security limitations, and the data may be exposed to alteration or contamination by intruders. Since satellite communication has become more crucial in the development of global communication networks, there have been worries regarding its security. This project proposes to use the QKD protocol, which relies on identification and privacy protection, along with blockchain technology to create A network of satellite communication. To accomplish this, an architecture that consists of conventional and constrained devices connected to the blockchain via a wireless heterogeneous network has been developed. The communication is conducted by registration, authentication, and revocation. After receiving the data from the satellite, the terrestrial base station will log all important parameters on the distributed blockchain and remove any certificates belonging to rogue nodes. The proposed Chain and QKD system, which is based on satellites, offers a high degree of security for rapidly growing applications such as self-driving cars, future 6G and larger networks, and the Internet of Things.

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.

The fusion of terrestrial radio and satellite communications will result in a world completely connected with sixth-generation (6G) networks. But there is a limitation of power and space available on satellites due to low computing power, limited storage space, and insufficient security occur. It is critical to utilize information storage and access protection in satellite networks efficiently to prevent data tampering and alteration. Satellite communications play an increasing role in global communication networks, creating security problems. Based on the Quantum Key Distribution (QKD) protocol, this proposal suggests a security and authentication method for satellite communication networks. A wireless and heterogeneous network architecture utilizes both open-source and commercial hardware to enable communication. The three stages of registration, authentication, and cancellation facilitate communication. As data is transmitted to satellites from ground stations, all measurements of significance are then logged on a decentralized blockchain. All certifications generated by rogue nodes are subsequently cleared from the blockchain by ground stations. It has been suggested that the technology be used with upcoming 6G networks, as well as the Internet of Things, self-driving cars, and other rapidly expanding applications.
