In this paper the block cipher RC6 is analysed. RC6 is submitted as a candidate for the Advanced Encryption Standard, it has 128-bit blocks and supports keys of 128, 192 and 256 bits, and is an iterated 20-round block cipher. Here it is shown that versions of RC6 with 128-bit blocks can be distinguished from a random permutation with up to 15 rounds; for some weak keys up to 17 rounds. Moreover...

By ERIC 1 ONDER AND DELIA BARRETO T HIS PAPER is concermied with the way imi which the volumue and shape of human red cell ghosts, two properties relate to the structure of the ghost and probably related to the structure of the red cells from which they are derived, behave as the red cells fromn which the ghosts are prepared are stored for increasimig periods of time at 4 C.
