The multivariate scheme HFEv- used to be considered a promising candidate for a post-quantum signature system. First suggested in the early 2000s, a version of
Multivariate cryptography is dominated by schemes supporting various modifiers to patch certain algebraic weaknesses. Typically these modifiers are linear in

The National Institute of Standards and Technology is in the process of selecting one or more public-key cryptographic algorithms through a public, competition
Currently the National Institute of Standards and Technology (NIST) is engaged in a post- quantum standardization effort, analyzing numerous candidate schemes
