Improved Impossible Differential Cryptanalysis of CLEFIA
Block ciphers cryptanalysis impossible differential attack
2009/6/2
This paper presents an improved impossible differential at-
tack on the new block cipher CLEFIA which is proposed by Sony Cor-
poration at FSE 2007. Combining some observations with new tricks,
we ...
Truncated differential cryptanalysis of five rounds of Salsa20
Truncated differential cryptanalysis five rounds Salsa20
2009/3/11
We present an attack on Salsa20 reduced to five of its twenty rounds.
This attack uses many clusters of truncated differentials and requires 2165
work and 26 plaintexts.
On Resistance of DES to Related-Key Differential Cryptanalysis
DES differential cryptanalysis related-key attacks
2009/1/21
The key schedule of the Data Encryption Standard is analyzed, and it is shown that the
properties of the permuted choice PC-2 transformation and the number of bits that are left
shifted during the k...
This paper studies the security of the block ciphers ARIA
and Camellia against impossible differential cryptanalysis. Our work im-
proves the best impossible differential cryptanalysis of ARIA and C...
Differential Cryptanalysis in Stream Ciphers
Differential cryptanalysis Stream ciphers RC4 A5/1
2008/8/22
In this paper we present a general framework for the application
of the ideas of differential cryptanalysis to stream ciphers. We
demonstrate that some differences in the key (or the initial state o...
PRESENT is proposed by A.Bogdanov et al. in CHES 2007 for extremely
constrained environments such as RFID tags and sensor networks. In this paper, we ¯nd
out the di®erential characteristic...
