Blakley, G.R. (ed.) et al., Advances in cryptology. Proceedings of CRYPTO ’84 (a workshop on the theory and application of cryptographic techniques held at the University of California, Santa Barbara, August 19–22, 1984). Berlin: Springer. Lecture Notes in Computer Science 196, 359-376 (1985).
Summary: New general properties in the $$S$$-boxes were found. Techniques and theorems are presented which allow to evaluate the non-substitution effect in $$f$$ and the key clustering in DES. Examples are given. Its importance related to the security of DES is discussed.
