Module Learning Outcomes
On successful completion of this module, students will be able to:
- Demonstrate an in-depth knowledge of the Transport and Application Layers of the OSI reference model;
- Have a good understanding of number theory and basic cryptographic constructs used in symmetric and asymmetric cryptosystems;
- Have a good understanding of the application of cryptographic techniques in network security, privacy and electronic payment systems;
- Have a working knowledge of network programming, sockets and the use of cryptographic libraries for securing network traffic.
This module introduces students to advanced topics in the areas of data communications, number theory and cryptography. A detail study is made of the TCP protocol in terms of multiplexing, flow and congestion control to understand the effects congestion in a large distributed network such as the Internet. A number of Application Layer protocols such as HTTP, DNS, AJAX and Websockets are studied to understand how Web Applications are designed today.
The students are also provided with an in-depth knowledge of number theory and cryptography which gives them an appreciation of how to secure data communication messages over an open network such as the Internet. This part of the course is quite mathematical in content.
Specific topics addressed in this module include:
- Transport Layer Issues – Multiplexing, UDP, TCP, Flow Control, Congestion Control;
- Application Layer Issues – HTTP, DNS, Web Applications;
- Network Security – Symmetric and Asymmetric Key Cryptography, Key Agreement Protocols, X.509 Certs and Public Key Infrastructure (PKI), Digital Signatures, Discrete Logarithms, Elliptic Curve Cryptography, Authentication Protocols;
- Electronic Payment Systems – Ecash, Bitcoin, Micropayments.
Teaching and Learning Methods
There are three lectures a week. In addition, there are two substantial individual programming projects as part of which students are required to demonstrate their working prototype.
