....p(x) 6= p(y) While the name saturation attack is new, such attacks have been known before. e.g. the Square attack (which was developed as a dedicated attack on the block cipher Square [3] is a saturation attack. It also works for other Square like ciphers such as the AES candidate Crypton [9, 10] and the AES nalist Rijndael [4] All these ciphers are 128 bit block ciphers with 8 bit data channels. The attack starts with a set of 2 8 plaintexts with one saturated channel, Supported by German Science Foundation (DFG) grant KR 1521 3 2. while all the other channels are constant. ....

....of the Rijndael key schedule and are faster than exhaustive search for up to seven rounds of Rijndael. 1 Introduction The block cipher Rijndael [3] has been proposed as an AES candidate and was selected for the secound round. It is a member of a fast growing family of Square like ciphers [2 6]. Rijndael allows both a variable block length of M 32 bit with M 2 f4; 6; 8g and a variable key length of N 32 bit, N an integer. In the context of this paper we concentrate on M = 4, i.e. on a block length of 128 bit, and on N 2 f4; 6; 8g, i.e. on key sizes of 128, 192, and 256 bit. We ....
