To-do list for Substitution box: edit · history · watch · refresh

Here are some tasks you can do:

    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)

    [edit] 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)

    [edit] 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)

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