| dc.description.abstract | 車載網路 (Vehicular Ad Hoc Networks，VANET) 是目前正在崛起的新興研究議題，隨之也發展出許多新的應用服務，提升交通運輸效率並增加行車安全。
VANET需要一種機制來管理快速增加的服務以免資源被浪費或成為攻擊工具，因此本研究從信任的角度出發，依據社會網路 (social network) 及其相關領域探討的「信任」概念以及結合資訊安全領域「存取控制」的原則設計出「以信任關係為基礎的存取控制」 (Trust Relation Based Access Control，TRBAC)，希望將社會網路的信任概念應用到VANET中，提供VANET管理其服務的可行方案。
本研究提出攻擊者散佈假訊息以及失竊車輛協尋兩個情境說明 TRBAC的使用情境。在攻擊者散佈假車禍訊息的使用情境進行模擬實驗，比較 TRBAC 與時間決(Freshest Message)、多數決(Majority Wins)兩種訊息傳播方式， TRBAC 能成功將車禍假訊息的數量抑制，比時間決減少約 60% ，比多數決減少約40% ~ 50%。本研究亦結合TRBAC 與行車記錄器提出新的車輛協尋服務流程，與傳統人力協尋相比在投入人力、資訊蒐集速度與資訊品質方面都具有優勢，可提升尋獲失竊車輛的機會。

| dc.description.abstract | VANET (Vehicular Ad Hoc Networks) is an Emerging research issues, and with it the development of many new applications improve transport efficiency and increase road safety.
It is necessary for VANET to develop a mechanism which is used to manage the variety of services so that resources could not be wasted or become attack tools. This research intends to use trust concept on VANET. We combine social network trust theory with access control design principle of information security areas and propose Trust Relation Based Access Control (TRBAC). This work defines trust on VANET and provides a scheme to manage the variety of services on VANET.
This research proposes tow scenarios for TRBAC, attackers spread false information and a new service for searching for stolen vehicles. For scenario 1, attackers spread false message, we compare the TRBAC and other tow modes of transmission messages, Freshest Message and Majority Wins. The results show that TRBAC successfully suppress the number false message than Freshest Message reduced by about 60%, less than Majority Wins about 40% to 50%.
For scenario 2, this work combines TRBAC with driving recorder and proposes a new service for searching for stolen vehicles. As compared with traditional service of searching for stolen vehicles, the new service is quicker when collecting information and provides good quality of information so that new service will enhance opportunities to find the stolen cars.
