WitrynaAn improvement on the algebraic attacks called fast algebraic attacks was presented in [7]. These attacks have been further examined in [3,21]. The ﬂrst algebraic attack on a block cipher was discussed in [30]. In [11] Courtois and Pieprzyk showed that AES can be attacked by solving a system of quadratic equations.
