Introduction to Cryptography and Computer Security
The overall goal of the course is to provide a solid theoretical foundation and hands-on experience in applying the theory to practice for cryptography, computer and communication security. The course materials cover common attack techniques, application of cryptography in security, authentication and authorization, network security, enterprise network defense, web security, and economics of cybersecurity. Besides the mechanisms for enhancing security that will be taught, a significant part of the course is dedicated to discussions on how design flaws in a system can be exploited to compromise security and, in general, the circumstances that lead to things going wrong. Students will have the opportunity to work on course projects that cover both the defense and offense aspects in the cyber space. Interesting research topics may be derived from course projects.

Operating systems (e.g., EECS 678 or EECS 750) and computer networking (e.g., EECS 563 or EECS 780), or the instructor's approval. In other words, a basic understanding of computer systems, including operating systems, networking, compilers, data structures, etc. This is a course that is primarily targeted at graduate students and at junior/senior-level undergraduate students in computer science and computer engineering.
If you experience any problems with lab equipment or your EECS account, contact the Engineering Technical Support Center immediately. Please be polite and as detailed as possible: Ticket Form
See the KU Registrar for important dates involving adding, drops, and refund information.
There will be on average one assignment per week, which could be a written homework, a programming project, or a reading assignment. At the end of the semester, you must also turn in a final report that focuses on a specific problem in computer and information security. The topics for the report will be seeked out by the students and approved by the instructor. There will also be a final exam. The break down of the final score of the course is:
|Programming assignments & homeworks||50%|
(includes recorded presentation & questions)
|A-||88% - 89%
|B+||86% - 87%
|B||80% - 85%
|B-||78% - 79%
|C+||76% - 77%
|C||70% - 75%
|C-||60% - 69%
|D/F|| 0% - 59%
Usually assignments are due at 11:59PM Central Time via Blackboard (unless otherwise specified) according to the date posted in the assignment. In general, expect a 20% per day penalty for late submissions. One minute or 23 hours still count as a whole late day. Each calendar day counts as a late day. In case a solution will be made available by the instructor, late submissions will no longer be accepted.
After successful completion of this course, students should be able to:
Cheating and plagiarism will not be tolerated and will be treated severely
whenever found. Unless an assignment explicitly states otherwise, all work
submitted for credit must be the student's own and is subject to the
provisions of the University of Kansas policies. Sharing your work or
copying is cheating, and submitting a work that is not all yours is also
considered cheating. Any cheating activities will result in an F for the course for
all parties involved. Reports of such detected academic misconduct will
also be made to your major department, school/college, and university,
which oftentimes will result in more serious sanctions. Students should
review the university policy on
"Academic integrity is a central value in higher education. It rests on
two principles: first, that academic work is represented truthfully as to
its source and its accuracy, and second, that academic results are obtained
by fair and authorized means. Academic misconduct occurs when these
values are not respected. Academic misconduct at KU is defined in the
University Senate Rules and
KU Student Affairs
From Section 2.6.1 of the University Senate Rules and Regulations: Academic misconduct by a student shall include, but not be limited to, disruption of classes; threatening an instructor or fellow student in an academic setting, giving or receiving of unauthorized aid on examinations or in the preparation of notebooks, themes, reports or other assignments; knowingly misrepresenting the source of any academic work; unauthorized change of grades; unauthorized use of University approvals or forging of signatures; falsification of research results, plagiarizing of another’s work; violation of regulations or ethical codes for the treatment of human and animal subjects; or otherwise acting dishonestly in research.
Citing Sources: If you use any code, such as a library or existing codebase, you must cite it. Not doing so is considered plagiarism and cheating.See Lecture 1 slides and video for more details on the collaboration policy. If you are in doubt, please ask.
The Academic Achievement & Access Center (AAAC) coordinates academic accommodations and services for all eligible KU students with disabilities. If you have a disability for which you wish to request accommodations and have not contacted the AAAC, please do so as soon as possible. They are located in 22 Strong Hall and can be reached at 785-864-4064 (V/TTY). More information can be found on the Student Access Services website. Please contact the instructor privately in regard to your needs in this course.
The instructor, Alexandru G. Bardas, considers the Zoom meeting environment to be a place where you will be treated with respect as a human being - regardless of gender, race, ethnicity, national origin, religious affiliation, sexual orientation, gender identity, political beliefs, age, or ability. Additionally, diversity of thought is appreciated and encouraged, provided you can agree to disagree. Activities within the University of Kansas community, including this course, are governed by the Code of Student Rights and Responsibilities. It is the instructor's expectation that ALL students experience the Zoom meeting as a safe environment.
