Recent rank-based attacks have reduced the security of Rainbow below the
security requirements set out by NIST by speeding up repeated kernel finding
operations using classical mathematics techniques. If quantum algorithms are
applied to perform these repeated operations, the rank-based attacks may be
more threatening and could dramatically lower the security level of Rainbow. In
this paper, we propose a novel MinRank attack called Q-rMinRank attack, the
first quantum approach to the key recovery attacks on Rainbow. By designing
quantum …
