[edit] Cryptanalysis

Does anyone know of any current cryptanalysis for Serpent?

I came across this white paper Preliminary Cryptanalysis of Reduced-Round Serpent stating something about "...recover the key for Serpent up to nine rounds." and "...how to break six rounds of Serpent..." Zer0Nin3r (talk) 10:43, 9 June 2008 (UTC)

This should go in the article, but I believe the best current known attack against Serpent is for an 11-round reduced variant, see:

• Biham, Dunkelman, Keller (February 2003). "Differential-Linear Cryptanalysis of Serpent" (PDF/PostScript). 10th International Workshop on Fast Software Encryption (FSE '03): pp.9–21, Lund: Springer-Verlag. Retrieved on 2007-03-08. 

(The full version has 32 rounds...) — Matt Crypto 11:34, 9 June 2008 (UTC)
