Abstract
A novel cross authentication model is proposed based on (t, n) threshold method in Layered and Grouped Structure (LGS) wireless multi-hop network, the issues of cross authentication and secure communication between nodes in different trusted domains are settled. With no CA, new scheme of cross certificate being issued and validated is designed, by which, the node identification can be authenticated in different trusted domains.
New Cross Authentication Mechanism
A double-layer Layered and Grouped (LGS) network structure has been designed based on the character of monolayer and multilayer wireless network structure [1]. At present, as for cross authentication mechanism, many researches emphasize particularly on wire network or centralized network configuration, while the detailed implement project on cross authentication in distributed wireless multi-hop network is little mentioned. This paper solves the problem of mutual trust establishment between different PKI domains, an efficient method is provided for node's mutual cross authentication and secure communication between different domains, and the node's identification authentication between domains is achieved.
