碩士 === 國立成功大學 === 資訊工程學系碩博士班 === 95 === Wireless　sensor　networks　(WSNs)　usually　are　applied　in　military　systems,　surveillance　systems,　etc.　Since　WSNs　always　are　deployed　in　open　environments,　the　security　mechanisms　in　WSNs　are　very　important.　Although　there　are　many　security　mechanisms　in　WSNs,　such　as　intrusion　detection　and　fault　tolerant　system,　few　of　them　are　proposed　to　detect　compromised　sensors.　In　this　paper,　we　propose　an　application-independent　compromise　detection　model,　distributed　cross-layer　compromise　detection　model　(DCCD),　making　use　of　a　distributed　mechanism　and　the　information　of　each　layer　in　the　communication　protocol　to　detect　which　sensors　were　already　compromised.　Due　to　the　characteristics　of　low　power,　low　computation　ability,　low　storage　space,　simplicity　and　high-efficiency　is　our　design　goal.　Only　when　compromised　sensors　can　be　detected,　the　WSNs　could　be　safer　in　practice.
