結合AES及RSA加密機制之無線生理訊號傳輸系統

本論文利用Ubiquitous healthcare (U-healthcare)觀念提出了一種體溫與血壓量測之生理訊號監測系統，我們將體溫與血壓等生理資料透過藍牙技術傳送至PDA顯示，再傳至後端管理伺服器建檔。為了保護患者的隱私及相關的生理資訊，我們利用AES及RSA之聯合加密演算法， AES演算法保護病患的生理資訊，及藉由RSA演算法保護AES的金鑰，並在安全性與運算速度上採取適當的妥協，此系統不僅提高人工抄寫記錄患者生理數據的效率，更能保護患者病例的隱私，此系統數據可由護理人員隨時隨地監看。最後，論文中我們以實做的方式驗證所提出的方法將可有效改善量測生理訊號之效率、正確性及安全性。

In this paper, we propose a measuring system of physiological signals including body temperature and blood pressure based on the concepts of ubiquitous healthcare. The physiological signals are transferred to a server via personal digital assistant (PDA) by Bluetooth technology. In order to protect the patients’ privacy and preserve the security of the relevant to measured signals, we use AES and RSA algorithms to encrypt the physiological data of the cared people and the key of AES algorithm respectively. The approach provides a well-compromise between the speed of encryption/decryption and the information security. In contrast to the conventional nursing, that is, via hand write and key-in the data to a computer, our proposed approach can effectively improve the efficiency, correctness, and security.
