Trust Mechanisms for Multi-owner Wireless Sensor Networks

Multi-Owner Wireless Sensor Networks are composed of devices used for different applications, each such application having its own Virtual Sensor Network. The different Virtual Networks must cooperate for multi-hop routing between nodes and for using each other´s services. This report analyzes the applicability of a trust model for secure routing, μRacer, which can be used to handle various attacks against the nodes and en encryption system based on the Skipjack algorithm to ensure data privacy. We evaluate these by implementing them in TinyOS and testing them using TOSSIM.
