Abstract. We provide the first proof of security for Tandem-DM, one of the oldest and most wellknown constructions for turning a blockcipher with n-bit blocklength and 2n-bit keyle...
We prove that Tandem-DM, one of the two “classical” schemes for turning a blockcipher of 2n-bit key into a double block length hash function, has birthday-type collision resist...
Abstract. In this paper, we give a security proof for Abreast-DM in terms of collision resistance and preimage resistance. As old as Tandem-DM, the compression function Abreast-DM ...
