对Loidreau秩度量密码体制的Coggia-Couvreur攻击的扩展
Extending Coggia-Couvreur Attack on Loidreau's Rank-metric Cryptosystem
摘要：
Coggia和Couvreur最近的一篇论文提出了一个多项式时间的密钥恢复攻击Loidreau的加密方案，基于秩度量码，一些参数。Loidreau方案的秘密矩阵分量是在与秩度量码相关联的域的定义子空间上选择的。我们部分扩展Coggia-Couvreur攻击处理的情况下，定义子空间的维数大于2。
英文摘要：
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.
