摘要

近來無線隨意網路中群體通訊是越來越明顯趨勢，這些在網路中群體之間會透過彼此路由相互溝通，然而當網路中群體數目越來越多的時候，在進行資料傳遞之前的認證佔整個傳輸過程一個很大的部份，而且群體的分布也會影響到傳輸的效率。我們建構了一種安全轉運路由機制來取代傳統的認證方式，這機制分成兩個階段，分別是建立安全通訊管道以及監督整個網路運作，來保證整個資料傳遞的安全性，同時省去認證以及只透過同群體之間路由的限制。從實驗的結果來看，我們這種方法在資料傳遞有較小的延遲、在能量上消耗的較少，能夠提升整個無線隨意網路的運作效率。

Secure group-aware communications only transmit data among group members. However, group members might separate into several sub-groups due to the natural of location. It is necessary to allow relay by a un-trust friends. In this thesis, we proposed a secure relay scheme called AFRS. It integrates two phase schemes: one for end-to-end secure channel establishment and the other for relay behavior monitoring. The transmitted data would be protected under the end-to-end secure channel. Attacks of routing are monitored and provide a countermeasure in the monitoring phase. As the experimental results, AFRS provides an efficient way to relay data securely.
