Looking Back at a New Hash Function

摘要

We present two (related) dedicated hash functions that deliberately borrow heavily from the block ciphers that appeared in the final stages of the AES process. We explore the computational trade-off between the key schedule and encryption in a block cipher-based hash function and we illustrate our approach with a 256-bit hash function that has a hashing rate equivalent to the encryption rate of AES-128. The design extends naturally to a 512-bit hash function.
