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

This information will not be available until 8 weeks before term.
To see assessment details from an earlier availability, please search via a previous term.

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, including Unit Evaluation
Feedback
New concepts and tools to learn each week, combined with regular journal entries and multiple tests, leaves little time for an in-depth understanding of topics.
Recommendation
Reduce the number of tests during the term, and make it clearer that during busy weeks (e.g., when tests are held, key points in a project) the journal entries can focus on reflections on the test and project.
Action Taken
Number of tests reduced from 5 to 3. However the weight of the final test was higher than past offerings, which led to concerns about the high stakes assessment being due at same time as other large assessments in this and other units.
Source: Unit Evaluation and Unit Coordinator Reflection
Feedback
The connection between the ciphers and skills learnt in this unit and the technologies graduates will work with is not clear.
Recommendation
Include more activities on cryptography for web technologies in the project, and include a task towards the end of the term for reflecting on the relevance of the learnt knowledge/skills to future jobs.
Action Taken
The project was changed to focus on deploying, testing and analysing security protocols (e.g. HTTPS, SSH) in the cloud. The practical nature of the activities and in-depth analysis of the role of cryptographic mechanisms in real world scenarios was appreciated by students. A topic was also introduced covering careers in cyber security. Students self-assessed their cyber security and networking skills against select job profiles.
Source: Student evaluations
Feedback
Tests are stressful due to level of difficulty, high stakes, and variety of topics covered in short time.
Recommendation
Reduce the weight of the tests in the unit, adding more focus on the practical activities in the project and journal.
Action Taken
In Progress
Source: Student evaluations
Feedback
The quality of the learning materials was appreciated, however the time needed to study the content covered is high.
Recommendation
Continue with the diverse set of learning materials, but incorporate more guidance on depth of understanding needed of each topic, e.g. via more quiz questions for self-assessment.
Action Taken

Feedback
Active use of GitHub and Teams for group work usually leads to higher quality project outcomes.
Recommendation
Demonstrate the benefits of GitHub and Teams for teamwork early in the term and allocate more marks to their use for the project.
