Abstract:In order to solve security threats such as eavesdropping, replay, interception and tampering caused by the wireless network transmission characteristics in the on-board edge computing network, this paper proposes a lightweight anonymous and efficient identity authentication protocol considering the limited resources of on-board terminal. This protocol is based on Chebyshev chaotic mapping algorithm, which avoids complex algorithms such as exponential and bilinear mapping used in most schemes, and effectively reduces the computational complexity in the process of identity authentication and key negotiation. In addition, the protocol can not only realize access authentication and handover authentication, but also realizes terminal anonymity, traceability, revocation and other security functions. The verification results of Scyther tool show that the protocol can meet the security requirements in the authentication process and resist various protocol attacks. Compared with the existing schemes, the total computing cost of the access authentication scheme proposed in this paper can be reduced by 67%, and the bandwidth cost can be reduced by 11%. In addition, compared with the access authentication scheme, the total computing cost and bandwidth cost of the proposed intra-domain handover authentication scheme can be reduced by 99.8% and 52%, respectively. The total computing overhead and bandwidth overhead of the inter-domain handover authentication scheme can be reduced by 80% and 37%, respectively. Performance analysis results show that the protocol has better computing and communication performance, so the protocol can solve the problem of efficient and secure terminal access and handover in the on-board edge computing network.
