中文摘要 透過車輛間彼此交換訊息的特性,車載網路能提供駕駛者及車輛有較多時間來反應突發狀況,可以大幅提升交通安全,確保訊息的傳輸具備足夠的安全性以及維持駕駛者的隱私是近年來車載網路中重要的研究議題之一。雖然已有不少學者提出相關的研究,但是如何同時兼顧效率、保護隱私及安全性卻仍舊存在改善的空間,本篇提出車輛能自行產生廣播所需假名及公/私鑰配對方法以提供適當保護隱私並降低所需的通訊負載,同時本篇論文方法也提供在車載網路中廣播訊息應達到的安全功能。就效率、隱私與安全整體評估我們的方法較其他方法略勝一籌。
英文摘要 Vehicular ad-hoc network (VANET) can improve road safety by taking the advantages of the information which are interchanged among vehicles since vehicles have more time to respond unexpected condition. Therefore, ensuring the transmission of messages with adequate security and maintain the privacy of drivers of VANET is one of the important issues in recent years. Although there are many related researches, but how to give consideration to efficiency, privacy preserving and security synchronously still have room for improvement. This paper proposed a self-generate pseudonym mechanism with privacy preserving and satisfies the security requirements in communication of VANET, reducing the communication overhead simultaneously. Our method is better than other methods on the overall evaluation of efficiency, privacy preserving and security.
