Abstract: In 1994, Peter Shor developed an algorithm that could theoretically defeat all number theory based cryptography (RSA, DSA, Elliptic curve) if a quantum computer can be built. Due to this concern, NIST (National Institute of Standards and Technology) is beginning a process to develop new cryptography standards that would be secure against both quantum and classical computers. In this talk, I would like to present new attack methods to two NIST post-quantum standardization candidates that both belong to MPKC (multivariate public key cryptosystem). One is called Himq-3 signature scheme proposed by Kyung-Ah Shim et al (2017). The other is LUOV (Lifted Unbalanced Oil Vinegar) signature scheme by Ward Beullens et al (2017).
