Teaching Rationale And Relationship

Lecture materials will be largely taught present-in-person and may include short podcasts or modified ReCAPs. They are to introduce the learning material, delivering content and for demonstrating the key concepts by example. Students are expected to follow-up lectures within a few days by re-reading and annotating lecture notes to aid deep learning. This will be aided by (1) scheduled online Q&A time via Zoom/Teams and (2) non-synchronized online discussion via Canvas.

Students aiming for 1st class marks are expected to widen their knowledge beyond the content of lecture notes through background reading (recommended textbooks).
Students are expected to spend time on preparing and completing the coursework and associated quizzes.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The examination tests the students' possession of knowledge as well as their understanding of the concepts and techniques that are relevant to cryptographic systems. The exam can be 24 hour take home if needed. The coursework allows them to assess their knowledge and understanding as the module progresses.
Study abroad students may request to take their exam before the semester 1 exam period, in which case the length of the exam may differ from that shown in the MOF.

N.B. This module has both “Exam Assessment” and “Other Assessment” (e.g. coursework). If the total mark for either assessment falls below 35%, the maximum mark returned for the module will normally be 35%.
