Fast Algebraic Attacks and Decomposition of Symmetric Boolean Functions [PDF]

IEEE Transactions on Information Theory, 2011
In this correspondence, first we give a decomposition of symmetric Boolean functions, then we show that almost all symmetric Boolean functions, including these functions with good algebraic immunity, behave badly against fast algebraic attacks.

Some results on fast algebraic attacks and higher-order non-linearities

IET Information Security, 2012
In this study, the authors investigate the resistance of Boolean functions against fast algebraic attacks and deduce a bound between fast algebraic immunity and higher-order non-linearity (it is the first time that a bound between these two cryptographic

Rewriting Variables: The Complexity of Fast Algebraic Attacks on Stream Ciphers [PDF]

Lecture Notes in Computer Science, 2004
Recently proposed algebraic attacks [AK03,CM03] and fast algebraic attacks [A04,C03] have provided the best analyses against some deployed LFSR-based ciphers. The process complexity is exponential in the degree of the equations.
