This key technique is to solve the issue of mutual trust establishment between different PKI domains in the future wireless network development for clients. Without Certificate Authority, By adopting threshold scheme, a new roaming hand-off authentication scheme between the different trusted domains in multi-hop wireless network is proposed, then we described and analyzed 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. and it can provide an efficient method for node's roaming hand-off and...
