论文摘要

我们对DME密码系统提出了结构性攻击(3,2,Q)。攻击恢复了第一个线性图的12个系数中的10个。我们还表明,如果已知这12个系数,则可以通过求解仅两个变量的二次方程的系统有效地获得其余的私钥。

We present a structural attack on the DME cryptosystem with paramenters (3,2,q). The attack recovers 10 of the 12 coefficients of the first linear map. We also show that, if those 12 coefficients were known, the rest of the private key can be efficiently obtained by solving systems of quadratic equations with just two variables.
