论文摘要
在这项工作中，我们利用了Liu，Yang，Han和Wang的2019年作品的基于代码的签名计划的严重安全缺陷。他们调整了McEliece密码系统以获得新计划，最重要的是，他们设计了有效的数字签名。我们表明，即使具有更长的公共钥匙，基于Mceliece的新加密方案也不比标准钥匙更安全。此外，签名的参数选择会导致大幅改善性能，但在协议中引入了脆弱性。
In this work, we exploit a serious security flaw in a code-based signature scheme from a 2019 work by Liu, Yang, Han and Wang. They adapt the McEliece cryptosystem to obtain a new scheme and, on top of this, they design an efficient digital signature. We show that the new encryption scheme based on McEliece, even if it has longer public keys, is not more secure than the standard one. Moreover, the choice of parameters for the signature leads to a significant performance improvement, but it introduces a vulnerability in the protocol.
