• review concepts in computational number theory and their relevance for the design of secure and efficient techniques in cryptography;
• describe and deploy common symmetric and asymmetric encryption algorithms used as standards in modern cryptosystems;
• compare and contrast the properties of hash functions and attacks on them, and be familiar with their use in digital signature algorithms and their role in security protocols;
• explain techniques for information hiding and secret sharing, and analyse their applications in security;
• analyse cryptographic protocols for implementing a wide range of security requirements; and
• critically discuss applications of cryptography including the latest and future trends.

This module provides an overview of a wide range of security aspects and techniques of computer networks, both cabled and wireless. It will introduce basic aspects of Information Security, comprising Security and Risk Management as well as Policies and Standards. It also covers Ethical and legal aspects of security and hence addresses the employability of the students in their future career. The module then goes on to the topic of Network Security, both from a theoretical and practical aspect: network attacks, vulnerabilities and controls are introduced and examined in practical lab sessions. Finally, cutting-edge topics such as Web and Cloud security complete the picture.

• Compare computer network architectures.
• Evaluate the performance of TCP under varying flow control and congestion conditions.
• Design an IP addressing scheme for a network.
• Define and calculate transmission performance over a communication link.
• Study and analyse characteristics of modulation methods.

60 credits

This module constitutes the major individual piece of work of the Masters Programme where the student carries out a project involving independent critical research, design and implementation (where applicable).

On successful completion of the module, students will be able to:

• Select, justify and use effectively the research methods and techniques appropriate for particular cases in order to carry out a literature search and an independent work of research
• Critically identify the need to position their research in the wider academic or business context and structure the dissertation format to agreed conventions
• Plan, manage and critically evaluate the project using the techniques and tools needed in order to bring it in successfully on time and within resourcing limits
• Identify and critically analyse real-world problems or knowledge gaps to which academic concepts and methods can be realistically applied to improve or resolve the problem situation
• Apply skills to show an ability to engage in academic and professional communication with others in their field through report and presentation
• Present critical awareness in applying appropriate legal, social or ethical obligations and when required, respond to the financial and other constraints of a corresponding business environment.

The module addresses theory and practice of wireless communication systems and networks, including the most recent wireless communications standards.

The first part will focus on the propagation characteristics of wireless channels and the main techniques for efficient communication, including modulation and channel coding. Characteristics and performance limits of wireless systems, techniques and tools to analyse them and methods for their design will also be covered.

The second part of the module will cover real-world wireless systems and networks, including wireless broadband systems and wireless sensor networks. It will provide practical and useful knowledge that can be readily applied in the wireless industry.

It covers the real-world, practical knowledge needed to understand, design, evaluate, deploy, test, validate and debug WLAN, WMAN and WPAN, as well as GPRS/ UMTS/ 3G and 4G and beyond networks and systems and Wireless Sensor Networks (WSN). Advanced technologies such as ultra-wideband communications and cognitive radio will also be addressed.

(For NCSC Certified Pathway)

This module will provide you with a comprehensive knowledge into the main areas of mobile computing and its security aspects. Mobile communication modalities will be covered, including 3G/4G communication networks, Wi-Fi and personal area networks, mobile privacy and ethical issues. The gained knowledge will be applied in different mobile computing business environments such as mobile healthcare (m-health), mobile commerce (m-commerce), mobile learning (m-learning) and mobile web services (m-WS). Mobile security assessment will be introduced in order to formulate appropriate security requirements. Key management protocols in typically ad hoc, wireless and location-dynamic environments will be presented and analysed. Emerging topics such as the Internet of Things (IoT), mobile clouds and distributed social network security will also be discussed. The module also provides hands-on practical exposure to apps development in location and context aware environments.

30 credits

The module addresses theory and practice of multimedia communication systems and networks, with a special focus on multimedia signals (audio, images and video) and relevant compression and transmission techniques.

The first part of the module focuses in particular on the representation of multimedia sources and on lossless and lossy compression methods for data, audio, image and video signals.

The second part of the module focuses in particular on the transmission of multimedia sources over communication systems and networks and on the strategies adopted to protect multimedia content from channel and network errors and losses.
