MULTI2 is the block cipher used in the ISDB standard for scrambling digital multimedia content. MULTI2 is used in Japan to secure multimedia broadcasting, including recent applicat...
SFLASH is a signature scheme which belongs to a family of multivariate schemes proposed by Patarin et al. in 1998 [9]. The SFLASH scheme itself has been designed in 2001 [8] and ha...
At ISW’99, Nishioka, Hanaoka and Imai proposed a digital signature scheme on ID-based key-sharing infrastructures. That signature scheme is claimed to be secure if the discrete l...
This paper shows that the actual proposal for an unbalanced Feistel network by Schneier and Blaze is as vulnerable to differential cryptanalysis as the DES. 1 McGuffin Schneier and...
