適用於車載網路匿名性批次驗證研究

因應日益增加的行車安全與交通流量管控的需求，近年來車載網路(VANET)已成為相當重要且熱門的研究議題，隨著車載網路相關技術的發展與進步，車載網路中的通訊安全需求逐漸被重視，如何在快速且眾多的車輛間安全地傳遞資訊則成為一大挑戰，而其中值得探討的議題則是車載網路中的安全認證問題。在進行通訊之前，必須先確認通訊的對方是可以被信任的，因此裝置彼此之間需要有合適的認證機制，但在車載網路的環境底下，由於行車速度較快，故傳統的認證機制有可能因為較花費時間而無法適用。同時，在使用車載網路時，為了考量使用者的隱私性，避免使用者的位置暴露，故需要採用匿名的方式通訊。因此，本文基於批次驗證的匿名簽名(AKABA)來提出改進方案，增加車載認證的安全度。

According to the increasing traffic safety and control needs, developing applications in vehicular adhoc network (VANET) has become an important and popular research topic in recent years. How to securely and rapidly transmit the messages between the vehicles is a major challenge in developing applications of VANET. To resist various malicious abuses and security attacks, the users in VANET needs to have an appropriate authentication mechanism to help them confirm that whether the communication objects can be trusted before communicate with them. However, the transmission time allowed to communicate with other objects can be very short in VANET due to cars are moving fast. Hence, the conventional authentication mechanisms cannot be applied to vehicular communication network as they spend too much time. In addition, in order to protect the user's privacy and avoid to disclosing the user's location, anonymous communication techniques are needed in VANET. Therefore, we propose an Anonymous Batch Authentication Scheme (ABAS) based on an Anonymous Batch Authenticated and Key Agreement Scheme (AKABA) to increase safety in data transmission over vehicular communication network.
