Module summary

The module aims to provide a broad overview of modern cryptography. The module will cover the fundamental security goals achieved through cryptographic algorithms and protocols, how they are formalised, designs that enable achieving those goals, and how formal security arguments can be made for the design achieving the security goals.

Module aims

The module aims to provide a broad overview of modern cryptography. The module will cover the fundamental security goals achieved through cryptographic algorithms and protocols, how they are formalised, designs that enable achieving those goals, and how formal security arguments can be made for the design achieving the security goals.

Module learning outcomes

By the end of the module the students will be able to:

  1. describe and apply the fundamental security properties provided by cryptographic algorithms and protocols;

  2. describe how these security properties are formalised;

  3. describe the implications of cryptographic security arguments;

  4. identify security requirements for a given practical scenario and identify the appropriate cryptographic tools to achieve the security requirements;

  5. assess whether given cryptographic algorithms and protocols meet identified security requirements; and

  6. analyse the security and efficiency of cryptographic protocols from both theoretical and practical points of view.

The information on this page is indicative of the module that is currently on offer. The University constantly explores ways to enhance and improve its degree programmes and therefore reserves the right to make variations to the content and method of delivery of modules, and to discontinue modules, if such action is reasonably considered to be necessary. In some instances it may be appropriate for the University to notify and consult with affected students about module changes in accordance with the University's policy on the Approval of Modifications to Existing Taught Programmes of Study.
