KASUMI is a block cipher which consists eight Feistel rounds with a 128-bit key. The confidentiality and integrity of UMTS, GSM and GPRS mobile communications systems depend heavi...
Abstract. Statistical Saturation Attacks have been introduced and applied to the block cipher PRESENT at CT-RSA 2009. In this paper, we consider their natural extensions. First, we...
Conventional cryptography uses encryption key, which are long bit strings and are very hard to memorize such a long random numbers. Also it can be easily attacked by using the brut...

Abstract. In this article, it is discussed how to construct a compression function with 2n-bit output using a component function with n-bit output. The component function is either...
We present several attacks against Achterbahn, one of the new stream ciphers proposed to the eSTREAM competition. Our best attack breaks the reduced version of the cipher with comp...
