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 propo...
