Riassunto

由於大量來路不明垃圾郵件(Spam mail)的氾濫，不但造成網路頻寬的浪費和郵件伺服器過濾系統的負擔過重，且導致收信人需花費更多的時間刪除這些垃圾郵件。根據Symantec的 統計數字顯示，垃圾郵件約佔郵件總量之70.5%，足見其氾濫是所有電子郵件使用者的困擾。垃圾郵件有77%是由殭屍網路(Botnet)中 的殭屍電腦所發送的，而垃圾郵件中夾帶的惡意程式碼感染使用者的電腦之後，產生更多的殭屍電腦，使得垃圾郵件氾濫的情況陷入惡性循環。 本研究在無法根絕殭屍網路的前提下，提出一套雲端認証服務，藉由 區分電子郵件的發送者的身份，過濾殭屍網路所發送的垃圾郵件。電子郵件的寄件者在登入 郵件系統時必須先通過身份認證，取得通行票證，後續每寄一封電子郵件皆憑通行票證向雲端服務索取認證碼，將認證碼附加在電子郵件的表頭裡寄出，收件端取出電子郵件表頭內的認證碼之後，透過雲端服務驗證認證碼的有效性。由於認證碼具有一次性與時效性，經過複製或變造的認證碼皆無法通過驗證。我們可以利用這些在雲端蒐集到的認證紀錄進行分析以偵測殭屍網路的分佈，依此建立黑名單，進一步的阻絕來自殭屍網路的垃圾郵件，也可以主動通知殭屍電腦的擁有者他的電腦已經遭到殭屍網路控制。 本研究在校內的私有雲上建置服務，在Apache的Hadoop分散式運算架構開放系統上開發基於雲端服務的反垃圾郵件服務，包括互動式挑戰 與回應認證、一次性認證碼以及殭屍網路黑名單等服務。
