HAIFA construction
This article needs additional citations for verification. (July 2017) |
The HAIFA construction (hash iterative framework) is a cryptographic structure used in the design of hash functions. It is one of the modern alternatives to the Merkle–Damgård construction,[1] avoiding its weaknesses like length extension attacks. The construction was designed by Eli Biham and Orr Dunkelman in 2007.
