#56 Fault Attacks on AES | Information Security 5 Secure Systems Engineering

 

Welcome to 'Information Security 5 Secure Systems Engineering' course ! This lecture focuses specifically on fault attacks targeting the Advanced Encryption Standard (AES), a widely used symmetric-key block cipher. It assumes viewers have a basic understanding of the AES algorithm. The lecture describes how an attacker can inject faults into the AES encryption process, typically targeting the last round of operations, to induce errors that reveal information about the secret key. It explains the concept of differential fault analysis (DFA) applied to AES, outlining how attackers can analyze the differences between faulty and correct ciphertexts to deduce key bits. Viewers will learn about the vulnerability of AES implementations to fault attacks and the techniques used by attackers to exploit these vulnerabilities.
