TUGrazX: Physical and Advanced Side-Channel Attacks
|
Software-based and physical side-channel attacks have similar techniques. But physical attacks can observe properties and side effects that are usually not visible on the software layer. Thus, they are often considered the most dangerous side-channel attacks. In this course, we learn both about physical side-channel attacks but also about more advanced software-based side channels using prefetching and branch prediction. You will work with these attacks and understand how to mitigate them.
About this course
On the hardware side, we will mount power analysis attacks on the cryptographic algorithms RSA and AES. We will see that simple power analysis attacks and differential power analysis attacks are powerful enough to obtain fine-grained information such as cryptographic keys, user input, or secrets of the operating system. This skill set and knowledge will give you the ability to spot these side channels in hardware and software projects. We will then cover countermeasures and mitigation strategies that allow you to develop side-channel-resilient hardware and software and protect your security-critical applications and sensitive information.
On the software side, we will learn about branch prediction an prefetching. We will learn how these mechanisms can be subverted into powerful side-channel attacks. You will need programming skills (C, C++, Python) and we will provide you with the knowledge required beyond these, including basics on hardware design, computer architecture, operating systems, and cryptography.
You will learn which attacks are relevant in the concrete environments you are working with, extending to your risk assessment skills. In a set of small exercises, you will demonstrate that you understood the techniques behind simple power analysis, and differential power analysis, as well as prefetch side channels and branch-prediction side channels.
