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.

On successful completion of this unit, you will be able to:
Late submissions will be accepted but will incur a penalty unless there is an approved Special Consideration request. A 12-hour grace period will be given after which the following deductions will be applied to the awarded assessment mark: 12 to 24 hours late = 10% deduction; for each day thereafter, an additional 10% per day or part thereof will be applied until five days beyond the due date. After this time, a mark of zero (0) will be given. For example, an assessment worth 20% is due 5 pm on 1 January. Student A submits the assessment at 1 pm, 3 January. The assessment received a mark of 15/20. A 20% deduction is then applied to the mark of 15, resulting in the loss of three (3) marks. Student A is then awarded a final mark of 12/20.

2 Indicative time-on-task is an estimate of the time required for completion of the assessment task and is subject to individual variation
Important! Please note that this is a BYOD (Bring Your Own Device) unit. You will be expected to bring your own laptop computer (Windows, Mac or Linux) to the workshop, install and configure the required software, and incorporate secure practices into your daily work (and play!) routines.
Each week you should complete any assigned readings and review the lecture slides in order to prepare for the lecture. There are three hours of lectures and a one-hour workshop every week. There uses hands-on exercises to reinforce concepts introduced during the lectures; you should have chosen a practical on enrollment. You will find it helpful to read the workshop instructions before attending - that way, you can get to work quickly!
For details of days, times and rooms consult the timetables webpage.
Note that Workshops commence in week 1.
You should have selected a practical at enrollment.
Please note that you will be required to submit work every week. Failure to do so may result in you failing the unit or being excluded from the exam.
This unit makes use of discussion boards hosted within iLearn . Please post questions there; they are monitored by the staff on the unit.

At the end of the semester, you will receive a grade that reflects your achievement in the unit
Your final grade depends on your performance in each assessment task and on your ability to perform well enough on the hurdle assessment tasks.
For each task, you receive a mark that reflects your standard of performance. Then the different component marks are added up to determine an aggregated mark out of 100. In order to pass the unit, this aggregated mark needs to be at least 50.
You also need to be achieve a minimum standard of performance on the hurdle assessment tasks.
Hurdle Assessment Task
Note that assignment submission in this unit is not a hurdle requirement. However, if you do not make a reasonable attempt at the two assignments, you will be unlikely to pass the unit.
Your final grade is then a direct reflection of the aggregated mark (provided that you satisfy the hurdle requirements) according to the following:
If you receive special consideration for the final exam, a supplementary exam will be scheduled in the interval between the regular exam period and the start of the next session. By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to submitting an application. You can check the supplementary exam information page on FSE101 in iLearn (bit.ly/FSESupp) for dates, and approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.
If you are given a second opportunity to sit the final examination as a result of failing to meet the minimum mark required, you will be offered that chance during the same supplementary examination period and will be notified of the exact day and time after the publication of final results for the unit.
