Cryptography Review

Overview

Computer networks are vital infrastructures needed for our day to day lives. Our increasing reliance on computers and networks of computers calls for robust measures to secure this infrastructure from malicious intents.

Present day networks face continuous threats from hackers. An understanding of the potential perils, and the strengths and  limitations of existing solutions to this problem is relevant not only for students specializing in
security, but for every person for whom a computer is an indispensable part of life.

Cryptography, once considered to be solely restricted to the realm of spies and secret service agencies, is an increasingly important building block for realizing computer and network security. An understanding of the principles of cryptography is therefore essential for comprehending approaches to realize secure networks.

The course will introduce private and public key encryption, key distribution (Kerberos, public key infrastructure), cryptographic hash functions, digital signatures, IP Security, Secure Socket Layer, WEP (Wired Equivalent Privacy
for wireless networks),  intrusion detection, Firewalls, denial of service, spam, email viruses, phishing, and an overview of many attacks that the Internet has experienced, especially in the last decade.

  2. The student could be tested on any material provided in the reference text and supplemental material provided by the instructor. Material beyond the scope of this course in the text and supplemental material will be explicitly pointed out by the instructor. There will be 4 quizzes, a midterm, and a final examination. The midterm and final exams will be comprehensive.
  3. Regular homeworks may be assigned on Tuesdays or Thursdays. They will be due on the Thursday of the following week. The penalty for late submission will be 10 percent for every day or part of day.
  4. All assignments / term papers submitted by the students should be in pdf format. Source codes if any should be attached as ASCII files.
  5. Graduate students may be required to answer additional questions in quizzes and exams.


Academic Honesty

Unless explicitly specified, it is to be understood that all homework assignments and tests are to be performed without collaboration. The departments academic honesty policy applies to this class and can be

Add / Drop Policy

Add/drop without penalty
A student has through the fifth class day into the semester to add a course and through the tenth class day to drop a course without being assessed a fee or academic penalty.

Drop after the tenth class day through the 30th class day into the semester

A student cannot drop courses after this period except in documented cases of serious illness, extreme hardship, or failure of the instructor to provide significant assessment of his/her performance. A request to drop a course during this period must be approved by the student's adviser and academic dean. The dean who permits the drop will specify its effective date. A student receiving permission to drop will receive a W on his/her academic record and be assessed a fee.
