Communication Network Security

5 February 2018 - 17 February 2018

This course provides an overall appreciation of secure communications when applied to activities on a communication network.

It covers the principles behind the most common forms of cryptography used in communication networks; teaches the generation of software to implement certain cryptographic mechanisms. 

The contents includes: the problem of security and its solutions; Classical cryptography: Substitution and transposition.  Block ciphers:  The DES algorithm; the AES algorithm.  Cipher modes of operation and message authentication codes (MACs).  Hash functions.   Public-key cryptography; the RSA algorithm, digital signatures, Diffie-Hellman key exchange, provable security, Paillier homomorphic encryption.


The module aims to enable students to develop a global view of security issues, threats and challenges as well as countermeasures developed in networked systems, with a focus on telecommunications networks. On completion of this module students should be able to evaluate telecommunication network security vulnerabilities and identify common security attacks, and interpret the principles behind the most common forms of cryptography and attack prevention used in communication networks and systems.
