Automated Reverse Engineering of Cryptographic Algorithms

Automated Reverse Engineering of Cryptographic Algorithms

In this article we present a practical case of automated reverse engineering of cryptographic algorithms. We first briefly recall how does our automated solution work. Then we explain step by step how it can be used in a practical case to identify and locate an AES implementation. Finally, we show how the localization results can be exploited by security experts to easily check the correctness of the cryptographic implementation.

A tale of 31C3 - Part 1

A tale of 31C3 - Part 1

The Chaos Communication Congress (CCC) is an enormous conference taking place each year from December 27th to 30th in Hambourg. This year was the 31st congress, named A new dawn in reference to the reaction towards Snowden's revelations, and it has received more than 12 000 attendees for more than 100 talks at the Hambourg Congress Center. Each year, the CCC is known for changing the rules of the hacker world in a security perspective. This year was no exception. In order for you to understand what the CCC looks like, we have written here after a summary of each great talk we attended. This is the first part of a serie of two articles, which summers up talks about firmware analysis, SMU or UEFI bypass, Thunderstrike vulnerabilities and crypto.
