Abstract. In this paper, we propose a 2/3-rate double length compression function and study its security in the black-box model. We prove that to get a collision attack for the com...
Abstract. We provide the first proof of security for Abreast-DM, one of the oldest and most wellknown constructions for turning a block cipher with n-bit block length and 2n-bit k...
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...
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 ...
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...
