Constructions and Attacks on Hash Functions

This paper presents a study about the construction models that are used to build hash functions. The study covers Merkle-Damgård, Sponge, HAIFA, Wide-Pipe, and Parallel-Tree constructions. Moreover, attacks on hash functions are also discussed in this paper. The major attacks on hash functions are presented with counter-attack methodology from the literature. This work helps the researchers in the area of cryptography hash functions to avoid any possibility of security threats in future designs.
