The widely used countermeasures against fault attacks are based on spatial, temporal, or information redundancy. This type of solution is very efficient, but it can be very expensive in terms of implementation cost. Thus, trying to propose a secure and efficient countermeasure for a lightweight cipher is a hard challenge, as the goal of a lightweig...

... present, in Section 5, a way to construct the protected S-box. Here, we present the results on the PRESENT S-box represented by the Table 3. However, we use an alternative form of the S-box composed only by logical gates, the algebraic normal form. ...Context 2
... construction is explained in the Algorithm 12. With this method, the representation of PRESENT is shown in Table 3 and consists of 62 logical gates. Several S-Boxes (found with an exhaustive search) with good cryptographic properties were tested, and none has an ANF constructed with less than 94 logical gates (the biggest one was created with 124 logical gates). ...Similar publications
Algebraic Fault Analysis (AFA) is a cryptanalysis for block ciphers proposed by Courtois et al., which incorporates algebraic cryptanalysis to overcome the complexity of manual analysis within the context of Differential Fault Analysis (DFA). The effectiveness of AFA on lightweight block ciphers has been demonstrated. However, the complexity of the...
