Nonlinear Approximations in Cryptanalysis Revisited

Nonlinear Approximations in Cryptanalysis Revisited

This work studies deterministic and non-deterministic nonlinear approximations for cryptanalysis of block ciphers and cryptographic permutations and embeds it into the well-understood framework of linear cryptanalysis. For a deterministic (i.e., with correlation ±1) nonlinear approximation we show...
