Overview
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.

Pre-requisite: COIT12202 Network Security Concepts
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. See details in the Assessment Policy and Procedure (Higher Education Coursework).
Offerings For Term 1 - 2027
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).

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.
Feedback from Student and tutor feedback
Some tutorial activities were too time consuming, making it hard to spend time exploring issues in depth.
Update tutorial instructions to include more realistic estimates of time required for tasks, and increasing time for discussion in class.
Feedback from Unit Coordinator reflections
When students used the class-wide Teams channel to complete group tasks in tutorials, observing the progress of students across different campuses was a motivation for students and useful feedback for the teaching team.
Include Microsoft Teams chat as a requirement in more tutorial tasks, e.g., sending encrypted messages, exchanging keys, conducting adversary-in-the-middle attacks.
