Introduction - aircrft
IOT 現在較常發生的問題是 cloud 的 server 比較容易被攻擊,如果 server 被攻擊就會使用者的資料全部洩漏(Device 聽命於 Server)。
較常使用的案例就比如像是「門禁系統」,而常見的門禁系統使用的傳輸協定就是 HTTP,然而 HTTP 比較常遇到就是裡面夾雜的資料(未加密)就會直接洩漏出去。
如果加密的 key 是寫在 framwork 上,理論上是可以從中去反推(reverse)出資料原樣,只要藉由特定的規則去推倒就能出來。在 IoT 上面有些加密的東西通常是會寫在 docuemnt 裡面,只要找出當中的規則,推導出原本的資料內容只是時間上的問題。
