Abstract
We examine the security of the class of substitution permutation private key block ciphers with respect to linear and differential cryptanalysis. A new S box nonlinearity criterion is proposed and it is shown that S boxes satisfying this criterion and having good diffusion improve remarkably the ability of an SPN to resist linear cryptanalysis and differential cryptanalysis
