The Hash Function Fugue is a cryptographic hashing algorithm, designed by Charanjit Jutla, Shai Halevi and Eric Hall from IBM T.J. Watson Research Center. Fugue was submitted to NIST as a candidate for the next SHA-3 hashing standard.
Fugue 2.0 is a tweaked version of the original Fugue Hash Function. It runs about two times faster for 256-bit output. It is based on additional security proofs, i.e. resistance to differential collision attacks, which makes even this faster version immune to differential attacks. Fugue 2.0 Specification.
