Unit description	Unit description This unit provides an introduction to modern applied cryptography. It deals with the concepts and techniques behind cryptographic primitives, such as hash functions, symmetric-key ciphers, public-key cryptography and digital signatures. It then explains the concept of cryptanalysis before addressing important cryptographic protocols. The unit concludes with a review of existing applications including blockchain and cryptocurrencies, electronic voting schemes, executable code signing, full disk encryption, etc.

General Assessment Information

Late Assessment Submission Penalty

Students enrolled in Session based units with written assessments will have the following university standard late penalty applied. Please see https://students.mq.edu.au/study/assessment-exams/assessments for more information.

Unless a Special Consideration request has been submitted and approved, a 5% penalty (of the total possible mark) will be applied each day a written assessment is not submitted, up until the 7th day (including weekends). After the 7th day, a grade of '0' will be awarded even if the assessment is submitted. Submission time for all written assessments is set at 11:55 pm. A 1- hour grace period is provided to students who experience a technical concern.

For any late submission of time-sensitive tasks, such as scheduled tests/exams, performance assessments/presentations, and/or scheduled practical assessments/labs, students need to submit an application for Special Consideration.

Assessments where Late Submissions will be accepted

In this unit, late submissions will accepted as follows:

Assignments 1 and 2 – YES, standard late penalty applies

Module Exams 1, 2 and 3 - NO, unless Special Consideration is granted

Weekly tasks - NO

Hurdle Assessment

The weekly tasks, i.e., weekly quizzes, are the only hurdle assessment for this unit. There will be 10 weekly quizzes. You are required to attempt at least 6 of the 10 to pass the hurdle. Note that the hurdle is the attempt, not the marks obtained. For example, you may secure less than 50% masks in the quizzes, but you will still pass the hurdle if you have attempted 6 or more of them. This activity is a hurdle to ensure that you are regularly attending and keeping up with the lectures and workshops preceding the quizzes. There is no opportunity to resit the hurdle, as it only requires you to attempt the quizzes. In the rare event that you missed a couple of quizzes resulting in you failing the hurdle, please email the unit convenor and apply for special consideration.

Special Consideration

The Special Consideration Policy aims to support students who have been impacted by short-term circumstances or events that are serious, unavoidable and significantly disruptive, and which may affect their performance in assessment.

Written Assessments and Module Exams: If you experience circumstances or events that affect your ability to complete the assignments and module exams in this unit on time, please inform the convenor and submit a Special Consideration request through ask.mq.edu.au.
Weekly quizzes: To pass the unit you need to attempt 6 out of the 10 weekly quizzes. A Special Consideration should only be applied for if you miss more than four of the weekly quizzes.

Requirements to Pass this Unit

To pass this unit, you must:

Achieve a total mark of 50% or more
Attempt at least 6 out of the 10 weekly quizzies
