近年來,無線感測網絡運用的層面越來越多元化,在不同的環境下有著不同的應用。無線感測網路中的基礎設施佈署之後,可於監測區域建立通訊和交換訊息。不過,在通訊的過程中,首要的問題是資訊的安全性。在這篇論文中,我們提出了適用於無線感測網路的一種植基於雙線性配對的動態金鑰管理及認證協定。我們使用動態金鑰管理和基於雙線性配對加密法(PBC)建立會議金鑰,基於雜湊函數的訊息驗證碼(HMAC),這些技術用以支援感測器與基地台之間的交互驗證。另外,我們也可以嵌入的全球定位系統(GPS)的能力於叢集結點中,透過叢集節點尋找出無線感測網絡的最佳路由路徑。我們提出的方案可以提供必要的動態密鑰管理、相互認證和會話密鑰保護安全;以及可以抵禦假冒攻擊、重送攻擊、蟲洞攻擊和消息操作的攻擊。
In recent years, wireless sensor networks have been used in a variety of environments; a wireless network infrastructure, established to communicate and exchange information in a monitoring area, has also been applied in different environments. However, for sensitive applications, security is the paramount issue. In this thesis, we propose using bilinear pairing to design dynamic key management and authentication protocol for the hierarchical sensor network. We use the dynamic key management and the pairing-based cryptography (PBC) to establish the session key, and the hash message authentication code (HMAC) to support the mutual authentication between the sensors and the base station. In addition, we also embed the capability of the Global Positioning System (GPS) to cluster nodes to find the best path of the sensor network. The proposed scheme can also provide the requisite security of the dynamic key management, mutual authentication and session key protection. Our scheme can defend against impersonation attack, replay attack, wormhole attack and message manipulation attack.
