Fault Attacks exploit malicious or accidental faults injected during the computation of a cryptographic algorithm. Combining the seminal idea by Boneh, DeMillo and Lipton with Differential Cryptanalysis, a new field of Differential Fault Attacks (DFA) has emerged. DFA has shown that several ciphers can be compromised if the faults can be suitably controlled. DFA is not restricted to old ciphers, but can be a powerful attack vector even for modern ciphers, like the Advanced Encryption Standard (AES).
