| Module Description: |
Security has become a very important topic in Computer Science. Underlying security is often a cryptographic system. Developers often have to design and implement systems which involve an element of security, and cryptography is usually underpinning such systems. Managers often manage security systems, and, again, those systems rely on strong cryptography. This module will explore how modern cryptography works, how it is implemented, and how it is usually incorporated into protocols.

Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
|
|
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
|
| No incompatible modules listed |
Co-requisite Modules
