Cryptanalysis of the Huang-Liu-Yang Cryptosystem from PKC 2012
Yosuke Todo and Keita Xagawa
Abstract
This short note describes a key-recovery attack against a multivariate quadratic cryptosystem proposed by Huang, Liu, and Yang (PKC 2012). Our attack is running lattice-basis reduction algorithms on a lattice constructed from the keys in the cryptosystem. The attack takes less than 20 minutes for the proposed parameter sets which are expected to be 80-bit and 128-bit security.
