An algebraic attack for forging signatures of MPPK/DS

, Tsinghua University

Abstract

We give an algebraic attack to forge the signature of a scheme called MPPK/DS, which can be achieved by solving a linear system in 5 variables with coefficients on $\mathbb{Z}/2^x q \mathbb{Z}$ for some odd prime $q$ and $x ≥ 1$.
