Improved Cross Authentication Model Based on Threshold Method in Wireless Network

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.
