The class meets MW 11:50-1:20 in CDM 214.
My office hours are MW 4-5:30pm (CDM 749, loop campus).
If you want to set up an appointment at another time, or simply ask a question, send email to mschaefer@cdm.depaul.edu.
The textbook for this course is Paar and Pelzl's Understanding Cryptography, Springer, 2010. The book is available for free (electronically) as part of the Library's Springer Computer Science Ebook collection.
For general information, see the official class syllabus. The prerequisites for this course is discrete mathematics (MAT 140) and a second introductory programming course (CSC 242 or CSC 243 or IT 212) .
The following is a very rough schedule, and we might depart from it.
|
1 |
Overview and Mathematical Background |
|
2 |
Stream Ciphers |
|
3-5 |
Block Ciphers, DES & AES, and modes of operation |
|
6 |
Midterm |
|
7 |
Public-Key Cryptography, Diffie-Hellman, RSA, DL |
|
10 |
Advanced Topics: Elliptic Curves, Digital Signature Schemes |
Homework, quizzes: 40%, Midterm: 30%, Final: 30%.
Midterm will be in class, on Monday, 5/6/2018 during classtime. The final exam will be on Monday, 6/10/2019, 11:30-1:30pm.
I will use the following grading scheme:
| Grade | Percentage |
| A | 95-100 |
| A- | 90-95 |
| B+ | 87-90 |
| B | 83-87 |
| B- | 80-83 |
| C+ | 77-80 |
| C | 73-77 |
| C- | 70-73 |
| D+ | 65-70 |
| D | 60-65 |
| F | <60 |
Throughout the quarter there will be extra credit problems; extra credit does not directly make up for points lost on homeworks or exams; instead it is added in with a weight to the final grade (i.e. not doing extra credit won't harm you, but doing it can move you up).
The midterm will take place during class. No make-up exams.
The course adheres to the university Academic Integrity Policy, the following is an excerpt from the policy:
Cheating: Cheating is any action that violates university norms or instructor's guidelines for the preparation and submission of assignments. This includes but is not limited to unauthorized access to examination materials prior to the examination itself, use or possession of unauthorized materials during the examination or quiz; having someone take an examination in one's place-copying from another student; unauthorized assistance to another student; or acceptance of such assistance.
Plagiarism: Plagiarism is a major form of academic dishonesty involving the presentation of the work of another as one's own. Plagiarism includes but is not limited to the following:
- The direct copying of any source, such as written and verbal material, computer files, audio disks, video programs or musical scores, whether published or unpublished, in whole or part, without proper acknowledgement that it is someone else's.
- Copying of any source in whole or part without proper acknowledgement.
- Submitting as one's own work a report, examination paper, computer file, lab report or other assignment that has been prepared by someone else. This includes research papers purchased from any other person or agency.
- The paraphrasing of another's work or ideas without proper acknowledgement.
Complicity: Complicity is any intentional attempt to facilitate any of the violations described above. This includes but is not limited to allowing another student to copy from a paper or test document; providing any kind of material—including one’s research, data, or writing—to another student if one believes it might be misrepresented to a teacher or university official; providing information about or answers to test questions.
A charge of cheating and/or plagiarism is always a serious matter. If proven, it can result in an automatic F in the course and, in case of a repeated violation, possible expulsion.
For homework this means that while you can talk to other students about the class material in general, you cannot talk about homework problems, or your homework solutions; you cannot share your homework solutions, either in written or electronic form. Any work you submit with your name on it needs to have been prepared and created solely by yourself, and you need to be able to explain it fully. The only people you are allowed to talk to about your homework are the instructor, the lab tutor, and CDM tutors. The only resources (written or online) you should be using are the textbook, and the materials linked off the class web-page.
Using materials prepared for other purposes (e.g., another course or work) needs the course instructor's prior permission.
An incomplete grade is given only for an exceptional reason such as a death in the family, a serious illness, etc. Any such reason must be documented. Any incomplete request must be made at least two weeks before the final, and approved by the Dean of CDM. Any consequences resulting from a poor grade for the course will not be considered as valid reasons for such a request.
