Mutant Differential Fault Analysis of Trivium MDFA
[chapter]
2015
Lecture Notes in Computer Science
In this paper we present improvements to the differential fault analysis (DFA) of the stream cipher Trivium proposed in the work of M. Hojsík and B. Rudolf. In particular, we optimize the algebraic representation of obtained DFA information applying the concept of Mutants, which represent low degree equations derived after processing of DFA information. As a result, we are able to minimize the number of fault injections necessary for retrieving the secret key. Therefore, we introduce a new
