Definition

Whirlpool is a cryptographic hash function outputting digests of 512 bits. The function structure is designed according to the Wide Trail strategy.

Background

Cryptographic hash functions are used to compress data in an irreversible way. The Wide Trail strategy to design secret-key ciphers was proposed by Daemen in 1995 [2]. The strategy became very popular after one of its products, Rijndael, was selected in 2000 to become the Advanced Encryption Standard [3].

Theory

Whirlpool iterates the Miyaguchi-Preneel hash scheme over the t padded message blocks m i , 1 ≤ i ≤ t, using the dedicated 512-bit block cipher W[k]:

$$\begin{array}{rcl}{ H}_{0}& =& IV, \\ {H}_{i}& =& W[{H}_{i-1}]({m}_{i}) \oplus {H}_{i-1} \oplus {m}_{i},\;1 \leq i \leq t, \\ \end{array}$$

where IV (the initialization vector) is a string of 512 0-bits. The 512-bit output of the hash function is simply the final state value H...
