中文摘要 車載網路是一種特別的行動隨意網路的型式,利用無線網路的環境來幫助車輛駕駛進行通訊,藉由快速的通訊,可讓駕駛者有較多的時間來對於突發的事件進行反應或提供補救措施,因此可以讓道路交通的安全性得到保障。但由於訊息的傳輸是透過無線網路來達到,因此讓惡意的攻擊者得以輕易的進行破壞、偷竊、竄改資訊…等惡意行為,故確保車載網路的系統可以提供匿名性、鑑別性、可追溯性、完整性、不可否認性、抵擋重送攻擊、車輛權限的廢旨、機密性、前後推安全這些安全性是極具重要性的,也是車載網路中的重要研究議題。在功能方面,一個完整的車載網路系統不僅僅提供路側基地台廣播訊息,更應該在車輛需要的情況之下,車載網路也能夠提供車輛進行廣播的動作,如此才能即時的提供的道路狀況,讓車載網路系統資訊更加豐富,保護人車行駛的安全。除了廣播的通訊之外,在本論文中,也提出點對點的通訊功能,若車輛在行進間,需要其通訊範圍內的其他車輛協助時,提供點對點私密的通訊功能,讓車載網路系統的功用更廣範也讓車載網路的使用者如魚得水。在本篇論文中,我們的貢獻為提供了廣播及點對點兩種通訊模式,並達到上述所有安全性的需求,這是以往的相關研究中無法完全提供的。
英文摘要 This paper proposes the vehicle communication scheme to ensure personal privacy security. VANET not only provides the road-side infrastructure units (RSUs) broadcast messages, but if vehicles require broadcasting messages, VANET also provides the ability for vehicles to broadcast to provide real-time road conditions. It makes the VANET more immediately and richer. It helps to achieve the main secure object that ensures the safety of people and vehicles traveling.
In addition to broadcast messages, this paper also proposes peer to peer communication. If the vehicle needs assistances of other vehicles in its communication scope while proceeding, both vehicles can exchange messages in an anonymous and secure way by taking P2P communication model. Non-repudiation and traceability makes the anonymous malicious vehicle can be traced and subject to legal sanctions on the premise of functionality and security. Including the vehicle authentication, anonymity, integrity, resistance of replay attacks, revoking vehicle, confidentiality, and forward and backward security, ten security functionalities in total in this paper. The scheme in this paper makes VANET apply more generously. Moreover, the communication channels and security are also more complementally.
