COIT13240 - Applied Cryptography

General Information

Unit Synopsis

In this unit, you will learn techniques for securing information and communications against adversaries, in particular with regards to confidentiality, integrity and authentication. Informed by the history of cryptography, you will learn the cryptographic primitives that are used to secure information today such as symmetric key encryption, message authentication codes, public key cryptography and digital signatures. You will also study future issues in cryptography, including the challenges raised by quantum computing. While you will learn and use basic mathematics, this unit will focus on cryptographic concepts relevant to cyber security specialists, rather than the mathematical underpinnings of the algorithms. This practical treatment of cryptography will be highlighted in laboratory tasks, where you will use software to attack and secure information in various realistic scenarios.

Important note: Students enrolled in a subsequent unit who failed their pre-requisite unit, should drop the subsequent unit before the census date or within 10 working days of Fail grade notification. Students who do not drop the unit in this timeframe cannot later drop the unit without academic and financial liability.

Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. In-class Test(s) 40%
2. Written Assessment 20%
3. Project (applied) 40%

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%).

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Source: Student feedback
Feedback
In-class tests varied significantly in the level of difficulty and time required to complete, making it difficult for students to prepare for the tests
Recommendation
Review the timing and questions in each in-class test, and provide additional guidance to students in advance about what they can expect in each test.
Action Taken
Nil.
Source: Student feedback, reflection of Unit Coordinator
Feedback
Even after completing self-study preparation tasks, students found some concepts difficult to comprehend during class
Recommendation
Allocate more time at start of class to review and discuss core concepts
Action Taken
Nil.
Source: Student feedback, reflection of Unit Coordinator
Feedback
Security project was very time consuming, mainly due to extra time needed to learn Python
Recommendation
Provide additional Python coding exercises and examples early in the unit
Action Taken
Nil.
Unit learning Outcomes

On successful completion of this unit, you will be able to:

  1. Discuss principles used to design secure cryptographic algorithms
  2. Explain the operation of attacks on cryptographic algorithms
  3. Compare the strengths and weaknesses of different cryptographic algorithms and their implementations
  4. Design secure information services using a variety of cryptographic algorithms.

The Australian Computer Society (ACS) recognises the Skills Framework for the Information Age (SFIA). SFIA is adopted by organisations, governments and individuals in many countries and provides a widely used and consistent definition of ICT skills. SFIA is increasingly being used when developing job descriptions and role profiles. ACS members can use the tool MySFIA to build a skills profile.

This unit contributes to the following workplace skills as defined by SFIA 7 (the SFIA code is included)

  • Information Security (SCTY)
  • Security Administration (SCAD)
  • Specialist Advice (TECH)
