隨著無線感測技術的進步，生醫無線感測器網路已逐漸廣泛地運用在各種醫療照護產業相關的應用上，以有效的蒐集、監控與管理病患的生理醫療資訊。不僅可以藉此提供病患完整的持續性照護，提高醫療照護的品質；更可以改善現行醫療資訊系統運用的效能，進而增加醫療診斷的正確性。由於在生醫無線感測網路中，感測節點之間資料傳遞的方式具有無線傳輸開放的特性，有心人士可以在節點間傳送資料時，透過竊聽或捕獲節點的方式，來取得節點監控搜集到的病患生理醫療資料，造成病患的隱私權受到損害。因此為了提昇生醫無線感測網路傳輸的安全性，符合醫療照護環境下之用，必須要使用秘密的金鑰機制以維護節點之間的通訊保密安全。
本論文中針對醫療照護環境下的無線感測網路中，設計了一套可以實際在醫療院所運作高效率的金鑰管理安全架構。這套安全性架構至少必須達成以下的目標：（一）提高整體系統的可用性；（二）保障病患的個人隱私；（三）避免惡意攻擊造成的醫療資源損耗；（四）提供具有安全漫遊特性的金鑰管理方式。為達成上述目的，本論文透過深入瞭解傳統生醫無線感測器網路上的金鑰產生機制，並利用雜湊金鑰鍊的特性，提出一個以雜湊金鑰鍊為基礎的高效率金鑰管理協定，以降低金鑰計算成本；並進而提出一個具有安全漫遊特性的金鑰管理方式，以提高配置生醫監控感測器的病患在醫院行動漫遊時資料傳輸的安全性與完整性。

The advance of wireless sensor technology facilitates the widespread applications of biomedical wireless sensor network in medical care industry for the effective collection, monitoring and management of patients’ physiological and medical information. This provides complete and continuous care of patients, improves the quality of medical care improves the performance of current medical information system and increases the accuracy of medical diagnosis as well. In a biomedical wireless sensor network, the data transmission between sensor nodes features open wireless transmission. The malicious intruders may access a patient’s physiological and medical information by tapping to or capturing a node, thus impairing the privacy of the patient. Therefore, to increase the security of biomedical wireless sensor network transmission to fit into the medial care environment, it is necessary to maintain communication security with encrypted key mechanism.
A highly efficient key management security structure used in a hospital was designed for a wireless sensor network used in medical care environment. This security structure had to achieve at least the following: (1) to increase the overall system availability; (2) to protect patients’ privacy; (3) to prevent waste of medical resource due to malicious attacks; and (4) to provide a key management method that allows secure roaming. To achieve these, the key generation mechanisms commonly used in traditional biomedical wireless sensor networks. Hash chain was used to propose a highly efficiency, hash chain-based key management protocol in order to lower the cost of key calculation. A key management method was proposed featuring secure roaming to increase the security and completeness of data transmission when a patient equipped with biomedical monitoring sensor is roaming in hospital.
