A Novel Roaming Hand-Off Authentication Scheme in Multi-Hop Wireless Network

摘要

It can be inescapable to solve the issue of hand-off authentication between the different trusted domains in the future wireless network development. By adopting threshold scheme, distributed hand-off authentication secure communication model is designed, then the process of cross certificate being issued and the steps of roaming hand-off authentication from node leaving former network to joining in new network are described and analyzed. Without CA (Certificate Authority), a new roaming hand-off authentication scheme between the different trusted domains in multi-hop wireless network is proposed, an efficient method can be provided for node's roaming hand-off and secure communication, the attack of single node being captured also can be avoided, which has better flexibility and security, and has important referenced value for the future application of wireless multi-hop network.
