QA

● Midterm brief survey 的要求?
A: brief survey 可以自行選擇有興趣的 Security-related topic，沒有主題或是格式限制，清楚明瞭佳，至少四頁。可以參考課程提及的reference。

● A brief Survey report about security issues 和 A brief Survey report about Techniques的差別?
A: 前者要求對某個有興趣的題目探討目前學術上的發展及問題，後者要求討論某項技術在目前應用的狀況或發展。

● Final Project 的形式?
A: applications realize/investigate 分組1~3人並要求30分鐘的 presentation 及 report。

● Mideterm brief Survey 與 Final Project Invertigate/Realize 的差別?
A: 我們建議 Final Project 可以作為 Miterm Survey 的延伸(不強迫)，所以應該要有更深入的內容以及自己的想法，
或是一些 implment 的實驗結果，簡單的 reproduce/分析/改進想法也可以
