The '''HAIFA construction''' ('''ha'''sh '''i'''terative '''f'''r'''a'''mework) is a cryptographic structure used in the design of [[Cryptographic hash function|hash functions]]. It is one of the modern alternatives to the [[Merkle–Damgård construction]], avoiding its weaknesses like [[length extension attack]]s. The construction was designed by [[Eli Biham]] and Orr Dunkelman in 2007.

Three of the 14 second round candidates in the [[NIST hash function competition]] were based on HAIFA constructions ([[BLAKE (hash function)|BLAKE]], SHAvite-3, ECHO). Other hash functions based on it are LAKE, Sarmal, [[SWIFFT|SWIFFTX]] and HNF-256. The construction of [[Skein (hash function)|Skein]] ([[Unique Block Iteration]]) is similar to HAIFA. Another alternative construction is the [[sponge construction]].
