  abstract  = {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.},
