| In this paper, we study the cryptanalytical techniques to perform Joux multi-collision, Kelsey and Schneier generic long message
second preimage attack and Kelsey and Kohno herding attack on the Merkle-Damgard construction as well as its variants with
XOR-linear/additive checksums and propose an advanced Merkle-Damgard construction, C-hash, by changing the feedback addition value, which can add the computation complexity of the
generic attacks, compared with Merkle-Damgard construction and its variants. |
