醫療資訊安全是一個很複雜的過程，它包含了患者的身分以及藥物資料和病情數據儲存訊息。因此，當醫療資訊管理做出不正確的判斷或是在缺乏人力資源的狀況下使得訊息容易造成錯誤。並考量到透過無線通訊媒介傳送訊息之醫療資訊的安全管理，本文提出安全認證協定的無線感測器網路(WSNs)進一步保護資料的機密性與隱私權不被侵犯，並且符合醫院的IT基礎設施，其中提出的認證協定通過Verilog硬體描述語言組成系統硬體架構、波形模擬得知結果是否符合以及在Altera DE2-70開發板顯示驗證結果再與 Visual Basic 6.0 所建構的驗證系統模擬得之結果是否相符完成功能驗證。擷取其輸出訊號於16702A邏輯分析系統上完成功能驗證，最後使用 Synopsys Design Vision 軟體將設計之系統合成為邏輯(gate-level)電路圖，同時分析不同認證架構系統所消耗的功率。

Medication safety administration is a complicated process involved with the information of patients, drugs and data storage. As a result, the medication errors may easily occur due to the un-correct judgment or lack of the human resource. Taking medication safety into consideration, this paper presents a secure authentication protocol for wireless sensor networks (WSNs), which is fit for the IT infrastructure of hospitals. Performance of proposed protocol is evaluated and simulated via Verilog hardware description language. The functionality of the proposed protocol is verified using Altera Quartus II software, and implemented in Altera Cyclone II DE2-70 FPGA development module. The output data’s of the development board are verified by event-driven programming language, Visual Basic 6.0. Also the output signals from the FPGA are measured in 16702A logic analysis system to complete functional verification. The logic (gate-level) circuit of the proposed architecture is synthesized using Synopsys Design Vision software. The XOR operation is applied to achieve the purposes of data protection.
