论文摘要
Coggia和Couvreur最近的一篇论文提出了基于级别代码的Loidreau加密方案的多项式时间键恢复攻击，用于某些参数。 Loidreau方案的秘密矩阵组件是根据与等级代码相关的字段的定义子空间选择的。我们部分扩展了Coggia-Couvreur攻击，以应对定义子空间尺寸大于2的情况。
A recent paper by Coggia and Couvreur presents a polynomial time key-recovery attack on Loidreau's encryption scheme, based on rank-metric codes, for some parameters. The secret matrix component of Loidreau's scheme is chosen over a defining subspace of the field associated with the rank-metric code. We partially extend the Coggia-Couvreur attack to deal with the case when the defining subspace has dimension greater than 2.
