Handover authentication enhancement scheme based on the chaos map and Chinese remainder theorem
As the next generation of the high-speed railway mobile communication system in China,the safety of 5 G-R is crucial for ensuring railway operation safety.Aiming at the problems of 5 G-R network handover authentication process,such as vulnerability to desynchronization attack,lack of forward security and high computing cost,an enhancement scheme based on chebyshev chaotic mapping and the Chinese remainder theorem for high-speed railway handover authentication is proposed.First,based on chebyshev chaotic mapping semigroup,a key negotiation mechanism is designed to realize bidirectional identity authentication between source base station which can effectively resist pseudo-base stations and desynchronization attacks and target base station during handover authentication.Then,by using the secret sharing principle of the Chinese remainder theorem,the session key of the train and target base station is derived,which ensures the secure transmission of link count value next-hop chaining count during handover,and overcomes the shortage of forward security in handover authentication.Finally,the security of the proposed method is verified by using the BAN logic formalization theory and Scyther security analysis tool,and the proposed method is compared with similar protocols for security and efficiency analysis.The results show that the proposed scheme has higher security and better performance than the comparison method in terms of communication and computing overhead,and can effectively meet the requirements of 5 G-R handover authentication security.
