In this poster, we present a Jasmin implementation of Mayo2, a multivariate quadratic (MQ) based signature scheme. Mayo overcomes the disadvantage of the Unbalanced oil and vinegar (UOV) scheme by whipping the UOV map to produce public keys of sizes comparable to ML-DSA. Our Jasmin implementation of Mayo2 takes 930 \(\upmu \) s for keygen, 3206 \(\upmu \) s for sign, 659 \(\upmu \) s for verify based on the average of 100 runs of the implementation on a 2.25 GHz x86 64 processor with 256 GB RAM. To this end, we have a multivariate quadratic based signature implementation that is amenable for verification of constant-time, correctness, proof of equivalence properties using Easycrypt. Subsequently, the results of this endeavor can be extended for other MQ based schemes including UOV.

摘要

In this poster, we present a Jasmin implementation of Mayo2, a multivariate quadratic (MQ) based signature scheme. Mayo overcomes the disadvantage of the Unbalanced oil and vinegar (UOV) scheme by whipping the UOV map to produce public keys of sizes comparable to ML-DSA. Our Jasmin implementation of Mayo2 takes 930 \(\upmu \) s for keygen, 3206 \(\upmu \) s for sign, 659 \(\upmu \) s for verify based on the average of 100 runs of the implementation on a 2.25 GHz x86 64 processor with 256 GB RAM. To this end, we have a multivariate quadratic based signature implementation that is amenable for verification of constant-time, correctness, proof of equivalence properties using Easycrypt. Subsequently, the results of this endeavor can be extended for other MQ based schemes including UOV.
