COURSE MATERIALS:
Introduction to Cryptography with Coding Theory, 2nd Edition, By Wade Trappe, Lawrence C. Washington, ISBN-10: 0-13-186239-1, ISBN-13: 978-0-13-186239-5, Published by Prentice Hall, © 2006, Pub. Date: Jul 15, 2005

COURSE DELIVERY METHOD AND INSTRUCTIONAL METHODS:

• Course delivery will be through live lectures. Lectures will also be recorded and the video files will be made available after the lecture.
• Instructional methods will include the use of Lecture slides, notes, textbook, e-mail

CLASS ROOM POLICIES:

• Attendance: Attendance is strongly encouraged. If you miss a class, you are responsible to learn all the material that was covered in class.
• Academic Dishonesty: Students are expected to maintain academic honesty. Academic dishonesty can result in an F for that assignment or exam (minimum) to an F for the course grade. Academic dishonesty includes (but is not limited to) plagiarism, copying answers or work done by another student (either on an exam or on out-of-class assignments), allowing another student to copy from you, and using unauthorized materials during an exam.
• Use of Tablets in the Classroom (formerly called the WMCI Statement): The Tablet PC platform has been adopted across the DSU campus for all students and faculty, and tablet usage has been integrated into all DSU classes to enhance the learning environment. Tablet usage for course-related activities, note taking, and research is allowed and encouraged by DSU instructors. However, inappropriate and distracting use will not be tolerated in the classroom. Instructors set policy for individual classes and are responsible for informing students of class-specific expectations relative to Tablet PC usage. Failure to follow the instructor’s guidelines will hinder academic performance and may lead to disciplinary actions. Continued abuse may lead to increased tablet restrictions for the entire class.
• Freedom in Learning Statement: Students are responsible for learning the content of any course of study in which they are enrolled. Under Board of Regents and University policy, student academic performance shall be evaluated solely on an academic basis and students should be free to take reasoned exception to the data or views offered in any course of study. It has always been the policy of Dakota State University to allow students to appeal the decisions of faculty, administrative, and staff members and the decisions of institutional committees. Students who believe that an academic evaluation is unrelated to academic standards but is related instead to judgment of their personal opinion or conduct should contact the dean of the college which offers the class to initiate a review of the evaluation.
• Americans with Disability Act (ADA): If you have a documented disability and/or anticipate needing accommodations (e.g., non-standard note taking, test modifications) in this course, please arrange to meet with the instructor. Also, please contact Dakota State University’s ADA coordinator, Keith Bundy in the Student Development Office located in the Trojan Center Underground or at 256-5121, as soon as possible. The DSU website containing additional information, along with the form to request accommodations is http://www.departments.dsu.edu/disability_services/. You will need to provide documentation of your disability. The ADA coordinator must confirm the need for accommodations before officially authorizing them.
• Assignments: Late submissions will NOT be accepted. Assignments should be submitted through WebCT. No other forms of submissions (such as email or printouts) will be accepted. You are responsible to have a working computer with an active network connection before the submission deadline to be able to upload the assignments in time. Failure to submit an assignment through WebCT before the deadline will result in 0 points for the assignment.
• Exams: Exams will contain questions based on material contained in the text book (which is covered in class), and on other material supplied by instructors such as slides and handouts.
• Make-up Exams:  If, due to circumstances beyond your control, you are unable to take an exam at the scheduled time, please contact me prior to the exam. Proof of the circumstances (e.g. doctor's certificate) will be essential; make-up exams must be taken within one week. Unexcused absences on the day of the exam (i.e., failure to notify the instructor prior to the exam period) can result in an F for that exam.

COURSE GOALS:
Student Learning Outcomes:
Upon completion of this course, the student should be able to,

FREEDOM IN LEARNING

Under Board of Regents and University policy student academic performance may be evaluated solely on an academic basis, not on opinions or conduct in matters unrelated to academic standards. Students should be free to take reasoned exception to the data or views offered in any course of study and to reserve judgment about matters of opinion, but they are responsible for learning the content of any course of study for which they are enrolled. Students who believe that an academic evaluation reflects prejudiced or capricious consideration of student opinions or conduct unrelated to academic standards should contact the Dean, College of BIS to initiate a review of the evaluation.

NOTE: Please go through the syllabus and inform us if you do not understand something or if you feel changes are needed. We will promptly discuss the matter and explain to you or make appropriate changes. This page was last updated Sunday, August 20, 2006
