PseudorandomFunctionsSummary: A pseudorandom function (PRF) is a keyed function $F : {\\\mathcal K}imes{\\\mathcal X}ightarrow{\\\mathcal Y}$ where, for a random key $k\\\in{\\\mathcal K}$, the function $F(k,\\\cdot )$ is indistinguishable from a uniformly random function,...
Pseudo-random functions (PRFs) introduced by Goldwasser, Goldreich, and Micali (FOCS 1984), are one of the most important building blocks in cryptography. A PRF family is a family of seeded functions {fs}, with the property that no efficient adversary can tell the difference between getting ...
Pseudorandomness is a central tool in complexity theory and cryptography. A pseudorandom generator (PRG) is a deterministic function G : {0, 1} n →{0, 1} m which stretches a short random seed into a longer output which looks random to any computationally bounded distinguisher. The question...

As a secure pseudorandom function (a.k.a. keyed hash function), SipHash can also be used as a secure message authentication code (MAC). But SipHash isnot a hashin the sense of general-purpose key-less hash function such as BLAKE3 or SHA-3. SipHash should therefore always be used with...
