At Asiacrypt 2004 Muller presents the first known preimage attack on MD2. The time complexity of the attack is about 2^104 and the preimages consist always of 128 blocks. We present a preimage attack of complexity about 2^97 with the further advantage that the preimages are of variable lengths. Moreover we are always able to find many preimages for one given hash value. Also we introduce many new collisions for the MD2 compression function, which lead to the first known (pseudo) collisions for the full MD2 (including the checksum), but where the initial values differ. Finally we present a pseudo preimage attack of complexity 2^95 but where the preimages can have any desired lengths.}, |
