This course is a research-oriented, graduate-level course, centering around both classic and state-of-the-art techniques on various aspects of compter and network security. The course involves both reading/discussing research papers and a term project/final report. The course aims to provide a thorough grounding on the computer and network security for the students who are interested in conducting research in this area, as well as a comprehensive background for those generally interested in networking or security. See below the completed paper list for the topics covered in the course.

Course Schedule

The papers will be presented as a seminar-style presentation in of 45 mins talk (including ~10 mins questions/discussions). (Note: You should consider the audience who are not expert in the relevant topic and provide a comprehensive and thorough technical background for the presented paper, which may require you adopt some materials not included in the paper.)

Presentations

Each student will give one full paper presentation selected from above pool. The slides used to present the paper in the class must be created by the presenters. Using materials from original authors or others is allowed but needs to be properly cited.

The slides should be sent to the instructor 2-3 days ahead of the presentation (a draft version will be fine), so the instructor can review the technical part and provide feedback, as well as arrange additional lecture for providing background if necessary.

---

Paper Reviews and Final Report

Each student is required to write two paper reviews. The Final report is either a research-oriented technical report or a survey paper for a specific topic within the scope of the course. Details and instruction will be given in the lecture and post later.

Grading and Policies

• 5% Class Participation
• 35% Presentations
• 20% Paper Reviews
• 40% Final Report
