Sample subject outline - Semester 2 2013

Note: Subject outlines often change before the semester begins. Below is a sample outline.

Rationale

Cryptographic techniques are widely used to implement computer and network security. As an IT security professional you may be required either to evaluate or implement information systems using cryptographic algorithms and protocols. This elective unit covers the main cryptographic technical concepts including encryption, digital signatures and cryptographic protocols. We assume that you are comfortable with basic mathematical concepts but we will introduce all the specialist mathematical tools required.

Aims

This unit aims to give you:
(a) an understanding of the fundamental algorithms and protocols of cryptology, with emphasis on their major applications; and
(b) the ability to apply mathematical and cryptologic techniques to solve real world information security problems.

Objectives

On completion of this unit you should be able to:

1. Apply basic concepts of cryptology, including modern symmetric and asymmetric ciphers, digital signatures, mathematics related to cryptology, and basic cryptographic protocols (GC1);


2. Demonstrate critical and analytical thinking in the application of cryptologic fundamentals to information and network security problems (GC2);


3. Communicate effectively in an Information Technology context (GC3);


4. Work independently on technical problems (GC5).

Key: Graduate Capabilities
GC1 - Knowledge and Skills
GC2 - Critical and Creative Thinking
GC3 - Communication
CG4 - Lifelong Learning
GC5 - Independence and Collaboration
GC6 - Social and Ethical Responsibility
GC7 - Leadership and Change

Content

This unit introduces you to the background and fundamental concepts of cryptology, in the areas of both cryptography and cryptanalysis. Topics include elementary number theory, classical ciphers, symmetric and asymmetric ciphers, information and complexity theory, prime numbers and factorisation, discrete logarithms, digital signatures and cryptographic protocols.
Note that this unit assumes that you satisfy the following "level of competency". If you do not satisfy this "level of competency" you may need to do extra work to achieve a satisfactory level.
Level of competency expected:
You should be familiar with the following concepts (with relevant applications) at an introductory level: discrete probability; logic, sets and functions; number theory; matrices; Boolean algebra.

Approaches to Teaching and Learning

The content of the unit is delivered through lectures, tutorials, software tools, and the QUT Blackboard site. Lectures cover theoretical aspects of the unit, and tutorial sessions provide an opportunity to solve exercises, based on the current week's lecture. Tutorial staff will be available to provide assistance.
The unit emphasises a 'hands-on' approach to learning through the illustration of new concepts through worked examples and demonstrations. You will use software tools in your completion of the tutorial sheets and assignment questions. You are encouraged to discuss the difficulties you are having with the assignment with your student peers or tutor.

Assessment

You will submit weekly exercises and an extended assignment - details will be announced during the lectures. You are expected to work on the assignments independently, but you can ask for assistance from the teaching staff.You can obtain feedback on your progress throughout the unit through the following mechanisms:

• ask the teaching staff for advice and assistance during lectures and tutorials


• your major assignment will be returned to you before the end of semester with comments on your progress


• private consultation with teaching staff
