Preliminary Cryptanalysis of Reduced-Round Serpent
Serpent is a 32-round AES block cipher finalist. In this paper we present several attacks on reduced-round variants of Serpent that require less work than exhaustive search. We at...

Related-Key Cryptanalysis of the Full AES-192 and AES-256
In this paper we present two related-key attacks on the full AES. For AES-256 we show the first key recovery attack that works for all the keys and has 299.5 time and data complex...

Stronger Security Bounds for OMAC, TMAC, and XCBC
OMAC, TMAC and XCBC are CBC-type MAC schemes which are provably secure for arbitrary message length. In this paper, we present a more tight upper bound on Advmac for each scheme, w...
