Overview

The popularity of the Internet, coupled with the explosive growth of mobile computing devices (phones, personal digital assistants (PDAs) and laptops), has led to the world of universal electronic connectivity. In this connected world, people access data and services on the Internet and communicate with each other anywhere and anytime. While this level of connectivity may bring us many benefits such as improving our quality of life and running services with global presence but with reduced costs, it does open vast opportunities for unauthorised access to data, services and other resources and for fraud and forgeries in commercial and business activities. Therefore, it is of paramount importance to increase both awareness and knowledge in protecting data and resources from unauthorised disclosure, in guaranteeing the authenticity of data in transit, and in protecting networked systems against attacks.

Aims

This course unit introduces students to the principles and practice of cryptography and network security, exploring popular cryptographic methods and security protocols and their applications for countering network-based security threats and attacks.

The course is designed for students who have some understanding of computer networks and protocols, but no background in security.

Syllabus

Introduction to Security

basic notions of security, security properties (confidentiality, integrity and availability), security vulnerabilities, threats and attacks, the use of attack trees in evaluating and classifying security vulnerabilities and threats, security models, policies and mechanisms

Cryptographic methods (or primitives)

classical encryption techniques, Feistel encryption and decryption, symmetrical (or conventional) ciphers, block cipher and stream cipher principles and operations, introduction to number theory, asymmetrical (or public-key) ciphers

cryptographic hash functions, Message Authentication Code (MACs), digital signatures

Establishing trust, cryptographic (or security) protocols

Diffie-Hellman key exchange, symmetric key distributions, digital certificates and Public Key Infrastructures (PKIs), user identification and authentication, single sign on, cryptographic protocol analysis and design

Network and Internet Security

IP security, web security, email security, Wireless Local Area Network (WLAN) security, e-commerce security, Cloud computing security

 

Feedback methods

Via question/answer sessions.
