Abstract The most basic way to cryptanalyze Multivariate Public Key Cryptosystems (MPKC) is solving the equation system generated by the public key and the ciphertext. Most commonly used way to solve the equation system is computing the Groebner Bases. Usually F4, commonly used Groebner Bases algorithm is used. But since F4 is designed for general polynomial sets, Mutant Grobner Bases (MGB) algorithm is more suitable for MPKC.
It is more appropriate using MGB in evaluating the security of MPKC. |
