A Study on a Secure Wireless Link Creation Based on Multi-path Routing Combined with Transmit Antenna Directivity Control

This paper proposes a secure wireless link creation scheme based on a multi-path routing in a single-hop wireless transmission environment, where multiple paths are created by directive transmission using the multipath component of wireless link which the link possesses naturally on its own. Moreover a secret sharing method is employed to divide the transmitted information into pieces of shared information and sending each pieces of information separately through the multiple paths. Computer simulation clarifies that with the proposed scheme, information recovery of the transmitted information can be confined to a limited area in the wireless space, i.e., the transmitted information is less exposed to the adversary around the legitimate terminals.
