Module content

The module is divided into the following areas:

• Introduction to security issues and security evaluation


• Introduction to cryptography


• Symmetric and Public Key schemes, in general


• Principles and details of symmetric cryptographic algorithms, e.g., Block Ciphers, MACs


• Asymmetric encryption and digital signatures, e.g. RSA/ElGamal


• Attacks and security of protocols


• Modern topics in security and applied cryptography, e.g. VPN, firewalls

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate their achievement of the learning outcomes.

All learning outcomes are assessed via coursework and formatively by labs.

Thus, the summative assessment for this module consists of:

The coursework is not fixed and varies year on year in the amount of practice vs theory.

• The first coursework covers the first half of the module (see descriptor) which is primarily applied cryptography.


• The second coursework covers the second half of the module (see descriptor) which is primarily security protocols and their analysis.

Grades for the coursework items are given against published assessment criteria with each piece of coursework.

Each coursework is an individual piece of work.

Formative assessment and feedback

Verbal feedback is given in lab sessions on the students attempts at the lab exercises and theoretical questions.

Written formative feedback is also given on the coursework.

Module aims

• develop the students understanding of computer security and its fundamental principles
• focus on the details of cryptographic mechanisms and how they are used to achieve security
• develop an understanding of the difficulties involved in achieving security and the approaches taken in analysing security solutions
• Introduce tools for exploring cryptography and for protocol analysis
• introduce elements of security proofs

Learning outcomes

Methods of Teaching / Learning

The learning and teaching methods include:

For each teaching week there will be

• Recorded/captured content


• Face-to-face lectures


• Face-to-face labs

There will also be a revision session to support the module.

 

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

Other information

Digital Capabilities

Computer Security is vital to all aspects of life and this module teaches both theory and practical skills to secure a system. These skills are now fundamental to developing solutions to problems as a computer scientist. Network systems are a part of most industries and the skills learned in this module will give students the knowledge to secure these systems

Employability

This module provides security, cryptographic theory and software skills that are vital in today’s industry. Students are equipped with theory practical problem-solving skills that allow them to work with and reason about security in computer and networked systems. These skills are highly valuable to employers.  Cyber Security experts are highly sought-after.

Global and Cultural Skills

Computer Science is a global language and the tools and languages used on this module can be used internationally. This module allows students to develop skills that will allow them to reason about and develop applications with global reach and collaborate with their peers around the world.

Resourcefulness and Resilience

This module involves practical problem-solving skills that teach a student how to reason about security in complex hardware and software systems through combining the foundation theory taught with practical technologies for systems that are in everyday use.
