Handover Authentication Mechanism Based on Consensus and Ticket for Space Information Network

Space information network is a key development object in the future communication field. However, the high-speed movement of satellite nodes causes frequent handover, and it is necessary to quickly verify the identities and permissions of handover parties to ensure the safety and reliability of the handover process. However, the traditional handover authentication technology in wireless network cannot well adapt to the characteristics of high dynamic topology and high link delay of space information network. To solve this problem, this paper proposes a handover authentication technology based on distributed consensus and Ticket. First, the user trust state is registered to the RSM network node using an improved Raft algorithm. Secondly, the Ticket tool is designed to assist in authentication. Finally, a safe and efficient handover authentication scheme is developed. Experimental results show that the proposed scheme can effectively reduce the handover delay and ensure the handover security.
