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 analyze the security of elastic block ciphers against key-recovery attacks. An elastic version of a fixed-length block cipher is a variable-length block cipher that supports an...
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...
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...
Understanding what construction strategy has a chance to be a good hash function is extremely important nowadays. In TCC'04, Maurer et al. [13] introduced the notion of indiff...
