F-OWF — One-way function

F-OWF (One-way function) is part of Cryptographic Library and Symmetric Primitives in the UC functionality encyclopedia. Status: open — no accepted UC formulation exists yet.

This is one of several purely local, hardness-based primitives (alongside F-PRG, F-CRHF, and F-MHF) with no cross-party interface to idealize — the UC composition theorem gives nothing here that a standard hybrid argument doesn’t already provide. It’s included in this encyclopedia only to record that absence explicitly.
