Research on Satellite Network Security Mechanism Based on BlockChain Technology

Due to satellite physical constraints in terms of available power and area, data processing capacity is low, storage and security are limited. It is a challenge to protect satellite network from illegal information access and use storage space effectively. In this paper, a blockchain technology-based on authentication and privacy protection scheme is proposed for a satellite communication network. to this aim, an architecture consisting of both conventional and restricted devices connected to the blockchain via a wireless heterogeneous network is deployed. The communication is carried out through registration, authentication and revocation. In this scheme, the satellite will forward the collected information to the ground base station, which will record all key parameters on the distributed blockchain and all malicious node certificates will be cleared from the blockchain by the ground base station. The simulation results show that the scheme has been greatly improved in terms of communication security and communication overhead.
