  • Learning & Teaching Activities
    Learning & Teaching Modes

    The course will be taught as a series of topics, and managed via MyUni. Each topic will involve a series of short video lectures, followed by quizzes to test understanding of the material, and provide students with immediate feedback.

    Fortnightly homework assignments help students strengthen their understanding of the theory and their skills in applying it, and allow them to gauge their progress.

    Weekly workshops provide opportunities to explore the theory in group discussions, and exercises to practice applying the theory.

    Weekly seminars run by the course coordinator are an opportunity to engage further with the topic in an active face-2-face setting.

    Students are expected to engage with all material on MyUni.

    Interaction with the course coordinator and discussion of any difficulties is strongly encouraged.

    Learning Activities Summary
    Cryptography is a vital aspect of cybersecurity. This course introduces modern cryptographic techniques in the context of information security in the workplace. It provides a sound understanding of the different types of cryptosystems available, the practical issues of applying cryptographic methods and key issues in the management of information security.

    The course considers the fundamental principles of cryptography, stressing the core information that a practitioner of cryptography needs to know. It does not focus on the mathematical details of current technology used in modern cryptography. The emphasis is on why cryptography is important, how it can be used, and issues relating to its implementation. Students will gain an understanding of issues relating to data security in the real world.

    The course does not assumed any prior knowledge of cryptography, and only assumes a limited mathematical background. There is no computer programming in this course.

    The topics covered in this course are:
    1. Introduction
    2. Historical cryptosystems
    3. Binary numbers
    4. Symmetric encryption (stream ciphers and block ciphers)
    5. Number theory (modular arithmetic and prime numbers)
    6. Public key cryptography (RSA and ElGamal)
    7. Overview (hybrid encryption)
    8. Data integrity (hash functions)
    9. Data origin authentication (message authentication codes)
    10. Digital signature schemes
    11. Entity authentication
    12. Key management
    13. Public key management
    14. Cryptographic protocols
    15. Secret sharing schemes

  • Student Feedback

    The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

    SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

  • Fraud Awareness

    Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student鈥檚 disciplinary procedures.
