This page does not agree with the page on Confusion and Diffusion. While that page associates diffusion with dissipating the relationship between a plaintext and a ciphertext (as here), substitution is there considered to be a component of confusion not diffusion. IMHO the first paragraph here needs to be reworked. Dvunkannon (talk) 20:44, 21 November 2007 (UTC)[reply]

hashes

Note that for some hashes (like the simple s-box hash) the s-box is also an important technique in hashes to increase the avalanche achievement behaviour of relatively simple algorithms. —Preceding unsigned comment added by 213.61.9.74 (talk) 12:29, 26 January 2011 (UTC)[reply]

Cache timing attacks against S-boxes

djb wrote an interesting paper about cache timing available here. While the paper focuses on AES, the attack is applicable against most encryption algorithm using large S-boxes. —Preceding unsigned comment added by 24.1.63.132 (talk • contribs)

Expansion

This article needs expansion. It doesn't talk much about what a S-box is, or how it works, at all. I'd expand it, but I don't know myself. Surgo 05:32, 20 November 2005 (UTC)[reply]

I second this. 68.126.192.237 06:01, 30 October 2006 (UTC)[reply]

Title should be S-box

The "S" may stand for "substitution" but no-one ever talks about a "substitution box", only an "S-box". If we're to follow the terminology used in the field, we should title this appropriately. — ciphergoth 18:02, 25 November 2008 (UTC)
