SHA-3 Derived Functions: cSHAKE, KMAC, TupleHash, and ParallelHash
Date Published: August 2016
Email Questions to:
NIST SP 800-185 specifies four types of SHA-3-derived functions: cSHAKE, KMAC, TupleHash, and ParallelHash, each defined for a 128- and 256-bit security level. cSHAKE is a customizable variant of the SHAKE function, as defined in FIPS 202. KMAC (for KECCAK Message Authentication Code) is a pseudorandom function and keyed hash function based on KECCAK. TupleHash is a variable-length hash function designed to hash tuples of input strings without trivial collisions. ParallelHash is a variable-length hash function that can hash very long messages in parallel.
