This was the official course website for TTM4205 Secure Cryptographic Implementations during Fall of 2023.

Course Description

The course covers how to implement, analyse, attack, protect and securely compose cryptographic algorithms in practice.
It goes in depth on how to implement computer arithmetic, attacking implementations using side-channel attacks and fault
injection, exploit padding oracles and low-entropy randomness, utilise techniques to defend against these attacks, and how
to securely design misuse-resistant APIs.

Portfolio Assignment

The evaluation in this course will consist of two assignments of 100 points total.

Weekly problems (40 points)

This assignment will contain the following kind of problems:

The submission deadline is December 10th at 23:59.

The problems are available here: PDF (updated 23/11)

Special Topic Project (60 points)

This assignment is to write a paper about either a topic not covered
by the lectures, or to cover a topic from the lectures more in-depth.

Most important guidelines:

Latex-template for the presentation:

The project description is available here: PDF (published 18/8)


You must pass both assignments to pass the course; at least 40% on each.

We will use the official NTNU grading scale to assign combined grades.

Lecture Plan

We have the following sessions this semester:
