Masked UOV Implementation

This is the C implementation of masked UOV (Unbalanced Oil and Vinegar) signature, and we implemented its pkc variant.

It is the artifact of the paper "Masked Solving of Linear Equations System and Application to UOV Signatures" (IACR TCHES 2026)

The unmasked part is built upon the UOV reference implementation.
