Wireless Multihop Transmissions for Secret Sharing Communication

Abstract

This paper proposes a novel routing protocol called neighbor-disjoint routing protocol in wireless multihop networks for secret sharing communication where data messages are transmitted along multiple wireless multihop transmission routes. Here, all wireless nodes including wiretapping wireless nodes receive data messages transmitted along at most one transmission route, i.e., They never receive data messages transmitted along multiple transmission routes. This is realized by the proposed protocol which ensures that there are no or less wireless nodes whose locations are included in wire less transmission ranges of intermediate wireless nodes included in different wireless multihop transmisison routes. In order to assure this security property, it is assumed that there are no wiretapping wireless nodes around the source and the destination wireless nodes since multiple wireless transmission routes are neighboring.
