Course Description: This is an introductory level course on the concepts and principles of data and network security. The focus of this class is on practical

aspects and application of cryptosystems in security protocols for networks such as the Internet. The basic topics to be covered include: Applications of cryptography

and cryptosystems for digital signatures, hash functions and message digests. Authentication, discussing the benefits and pitfalls of different authentication schemes,

e.g. PKI and Kerberos. Secure group communication, including key distribution and key management. Network security protocols for wired and wireless networks

e.g. IPsec, SSL/TLS, WEP, WPA. Cyberattacks and countermeasures, (Distributed) Denial of Service attacks, firewalls, Email filtering, viruses, worms. Security in

wireless ad hoc and sensor networks and Grid/Cloud security. Security for mobile phones and end-user devices.

Course Handouts: Any handouts distributed in class will also be in the class website listed above.

Class Account: The handin directory for this class is on cse.unl.edu and will be called "cse496". To submit homeworks online, please use webhandin. If you

See "Textbooks" and "Additional Resources" sections on the class homepage for other texts, websites etc.
Articles from recent journals and conferences will be assigned throughout the semester. Relevant chapters from other textbooks will also be made available,

as necessary.

Homework Assignments: There will be 3-4 homework assignments in this class. There will usually be a programming

part in each homework.

Project/Term Paper: This is your opportunity to demonstrate your understanding of the subject material and your abilities as a researcher. The project report/term

paper should be no more than 15 pages long and should be about an active area of research in data and network security. The project report may describe

(1) Implementation of a network security protocol or secure application in Java, C++, Perl, Tcl/Tk etc., or

(2) Simulation-based study of network/security characteristics, or

(3) Critical study of specific network-security issues.

Students registered for CSCE896 credit must complete a project and submit a report. Students registered for CSCE496 credit may submit a term paper or a project

report. Up to 2 students can be part of a project team. A special emphasis this semester will be on projects involving mobile phone app development (for iPhone,

Android or Windows Phone 7 environments).

Academic Integrity: All submitted work must be your own contribution and nobody else's! Collaboration in homeworks and exams are not allowed. Unless you

are part of a team, collaboration in a project is also not allowed. You may, however, discuss project ideas with others before you turn in your project proposal. The

department's academic integrity policy is at http://cse.unl.edu/undergrads/academic_integrity.php.

Exams

Midterm exam I and Midterm exam II, one before spring break and one after (Dates TBA) (in class). There will be no final exam in this class. However, there will

be project presentations during dead week and finals week. Examination must be taken at the time above; there are no make-up examinations, except for health reasons

or other emergencies.

Regrades In general, papers/assignments to be considered for regrades must be turned in no later than one week after the graded papers/assignments were made

available, not from when the student picked up her or his paper. Similarly, any misrecorded grades must be reported within a week of their posting, except as will

be announced at the end of the semester. Note, that you may not (re)submit any material during the regrading process.

Questions? Please send e-mail to me, byrav@cse.unl.edu (to be read by the instructor only!) or post them on the class mailing list, for the class (preferred!).
