This course provides the necessary tools for analysing systems and security protocols.

In security I, you learned about the adversarial environment and how difficult it is to secure IT systems. In security II, you learn about the foundations of cryptography and security protocols and ways to analyze their security.  You will learn how security properties are not compositional; that security is not absolute, that is, any "secure" system leaves residual assumptions, especially about trust.
Specifically, this course provides the theoretical and practical foundation for understanding and working the area of Cybersecurity: 

  • cryptography
  • security protocol design techniques
  • tool-based practical verification, e.g., using Proverif 
  • formal techniques in computational and symbolic models
  • security policies and properties, including IndCPA and IndCCA security 
  • case studies 

Formal prerequisites

Security I (7,5 ECTS), elective course on the MSc in Software Design

Discrete Mathematics (7,5 ECTS), mandatory course on the MSc in Software Design

Introduction to Programming (15 ECTS), mandatory course on the MSc in Software Design

Intended learning outcomes

After the course, the student should be able to:

  • Design and analyze cryptographic protocols for adversarial environments
  • Analyze basic cryptographic protocol designs in the computational model
  • Explain and apply proofs by reduction to prove the security of cryptographic constructions
  • Explain cryptanalysis and timing attacks
  • Analyze the properties of security protocols using tools
Learning activities

The course comprises lectures, lab sessions. In parallel, a project runs throughout the course. There will be 12 weeks of lectures, 2 weeks of project work only.

15 April ´20: The exam form change from A11 (4 hours) to C22 (8 hours) due to the Covid19 situation + Fraud check after the exam submission.

Mandatory activities
There will be six quizzes on Learn-IT. To be eligible for the exam you must reach at least a 50% average (of all quizzes total).

At the end of the course, you must submit as a group a project to Learn-IT, which will be evaluated pass/fail. To be eligible for the exam, you must pass the project.

The student will receive the grade NA (not approved) at the ordinary exam, if the mandatory activities are not approved and the student will use an exam attempt.

Course literature

The course literature is published in the course page in LearnIT.
