Course Description and Objectives:
The objective of this course is to provide students with fundamental concepts and
principles in the areas of computer and network security, including public and private key
cryptographic algorithms and their applications, authentication protocols, hash functions,
network access control mechanisms, network attack techniques and methods to defend
against them, characteristics of typical security architectures and protocols.

Grading Policies
Grades will be based on the following:
Attendance
Homework:
Project:
Midterm:
Final:
5%
10%
10%
30%
45%
No makeup exam will be given due to personal reasons.
The final grade is on curve. The cut off for undergraduate students is 5 points lower than
that of graduate students. For example, if the cut off for undergraduate students to get A
is 80, the cut off for graduate students to get A is 85.
Assignments: Compared to graduate students, undergraduate students will have less
coverage on the written assignments.
Project: Compared to graduate students, undergraduate students’ projects will have less
implementation of the basic algorithms.
Student with Disabilities
This course complies with university policies on disabilities. Please see the Student
Handbook for more details.
Academic Honesty:
Scholastic dishonesty will not be tolerated. We encourage discussion of homework and
class projects. However, the final product submitted for the grade must be the individual
work of the person turning it in. If codes from two or more students are essentially
identical, the assignments may be rejected with no credit for any of the students involved.
Cheating and plagiarism in tests and quizzes will receive the same penalty.
Late policy
All assignments must be turned in at the beginning of the class on the due date specified.
Late assignments will be penalized 10% per day and will be accepted within maximum 2
days after the due date. Assignments that are more than 2 days late will not be
accepted. All assignments should be typed. Handwritten assignments will not be
accepted.
