Research on satellite communication authentication technology based on CL-PKC

Abstract： With the continuous development of satellite communication technology, satellite communication networking technology has received more and more attention, and its related security problems are more prominent. This paper studies satellite communication authentication technology, analyzes the characteristics of satellite network and security authentication requirements, and proposes an authentication scheme based on identity password system, which realizes identity authentication and key negotiation，and protection of the identity information of legitimate users. Simulation experiments are carried out to verify the security and feasibility of the protocol, and the results show that the proposed scheme achieves secure and efficient authentication effect.
