Course Description

This course aims to enhance students’ knowledge in cryptography as well as information security and privacy, in both theoretical and practical ways. The course introduces cryptography at an elementary level, enabling students to appreciate on its application to information security and privacy.

Daily applications of cryptography will be discussed, including digital certificate and Public Key Infrastructure (PKI), Virtual Private Network (VPN), wireless communication security, as well as security and privacy issues in online social networks.

This is the (pretty old) description from the university. In this semester, we aim to cover all the basics of cryptography, network security, web security, and system security. Students will gain a comprehensive understanding of these major areas of cyber security at an introductory level.

Learning Outcomes

At the end of the course, participants will:

  • Gain a comprehensive overview of cyber security;

  • Obtain essential knowledge about cryptography;

  • Understand protocols used to protect network security;

  • Have a basic understanding about web, system, and mobile security;

  • Be able to design and finish a project related to security and privacy.

Learning Activities and Assessments

  1. Two individual written assignments 20%: one for cryptography and one for network security. Each takes 10 marks.

  2. Group project presentation and report 30%: six students in a group (one or two groups could involve only five students). Besides giving a presentation in class (a maximum of 30 minutes each group), each group needs to write a report with a minimum of 4 pages (references included) in the ACM format (see its Latex or Word templates). A list of project topics will be specified in the project page.

  3. Final course examination 50%: Students must sit for the final examination in the end of the course.

  4. Participation in class (bonus).
