  2. Kris Gaj • Research and teaching interests: • cryptography • network security • computer arithmetic • FPGA & ASIC design and testing • Contact: • The Engineering Building, room 3225 • kgaj@gmu.edu Office hours:Wednesday, 6:00-7:00 PM Monday, 7:30-8:30 PM

  3. NETWORK AND SYSTEM SECURITY • Advisors: Kris Gaj, Jens-Peter Kaps • ECE 542 Computer Network Architectures and Protocols– S.-C. Chang, et al. • ECE 646 Cryptography and Computer Network Security– K. Gaj, J.-P. Kaps– lab, project • ECE 746 Advanced Applied Cryptography– K. Gaj, J.P. Kaps – lab, project: C/C++, VHDL, or analytical • ISA 656 Network Security– A. Stavrou • ECE 699 Cryptographic Engineering– J.-P. Kaps, K. Gaj

  6. Lecture • viewgraphs / whiteboard • viewgraphs available on the web • (please, extend with your notes) • books • 1 required (Stallings) • 1 optional (all chapters available on the book web page) • articles (CryptoBytes, RSA Data Security Conf., CHES, • CRYPTO, etc.) • web sites - Crypto Resources • standards, FAQs, surveys

  7. Homework • optional assignments short programs vs. analytical problems or HDL codes • More time consuming • Most time spent on debugging • Relatively straightforward • Typically less time consuming • More thinking • Little writing

  8. Midterm exam • 2 hours 30 minutes • multiple choice test + short problems • open-books, open-notes • practice exams available on the web • midterm exam review session - optional Tentative date: Wednesday, October 27th

  9. Final exam 2 hours 45 minutes Multiple choice + several problems Wednesday, December 15 7:30 – 10:15 PM

  10. Laboratory • labs based on three major software packages • CrypTool • GnuPG for Windows or GnuPG for Linux • MAGMA Computational Algebra System • done at home or in the ECE labs: • software downloaded from the web • based on detailed instructions • grading based on written reports (answers to • questions included in the instructions)

  11. Project (1) • original • useful • depth, originality • based on additional literature • you can start at the point where former students ended • based on something you know and are interested in • software or hardware • may involve experiments • teams of 1-3 students

  12. Project (2) • about three weeks to choose a topic and write • the corresponding specification • regular meetings with the instructor • a few oral progress reports based on Power Point slides • draft final presentation due at the last progress report • written report/article, IEEE style • due Wednesday December 1 • short conference-style oral presentations • Wednesday, December 8 • contest for the best presentation • publication of reports and viewgraphs on the web

  13. Project (3) • Project reports/articles requirements • - IEEE style • - 15 pages maximum • - appendices possible but do not influence • the evaluation • Review of project reports • reviews done by your fellow students • reviews due, Sunday, December 5, midnight • final version of the report due Tuesday, • December 7, midnight

  14. Project (4) • Project presentations (Wednesday, December 8, 7:30-10:00PM) • - conference style • - open to general public (in particular, • students from previous years), ECE seminar credit • - 10 minutes for the presentation + 5 minutes for Q&A • - time strictly enforced

  15. “Typical” course difficulty time This course difficulty time
