... algorithms in symmetric cryptosystems is arguable. It had been widely known that most symmetric cryptosystem’s security levels will be simply reduced by half due to the asymptotic behavior of the query complexity of ... See full document

... Independent to our work, Ashur [7] described a method for finding linear trails that work only against SIMON-like ciphers. This method finds a multivariate polynomial in GF(2) repre- senting the r-round linear ... See full document

... In this article, we propose a new technique named key-dependent sieve to further reduce the memory complexity of MITM attack. In particular, we apply this technique to attack on 9-round AES-192, 8- round ... See full document

... The direct algebraic attack is the most straightforward way to attack a multi- variate cryptosystem such as HFE(v-). In this attack, one considers the public equation P (z) = h as an instance of the MQ-Problem. In the ... See full document

... Despite of some basic evaluations carried out on KLEIN by the designers [1], its real security level is not determined without further external analysis. So far, some cryptanalyses have been published on KLEIN, most of ... See full document

... The linear cryptanalysis shown by the designers [6] did not consider the depen- dence of the S-box. The 126-round linear characteristic eliminated by 42-round linear approximation is not accurate, due to the ... See full document

... The above analyses assume that one only considers one byte of the subkey that is equivalent to the penultimate subkey. However, if we consider more bytes of the penultimate subkey then fewer δ-sets are required. An ... See full document
