| 摘要: |
| 本文证明了McEliece公钥体制中的公开钥矩阵实际上就是一个Goppa码生成矩阵，指出Adams和Meijer对McEliece公钥体制安全性分析的不合理之处．本文的结果对KorzhikTurkin攻击是一种理论上的支持，并与一类基于纠错码的公钥体制的安全性密切相关． |

| Abstract: |
| Contrary to the Adams_Meijer analysis，in this paper it is proved that the public matrix G'in the McElieee's cryptosystem and all other matrices in the R_equiva-lence class of G'are still generator matrices of Goppa codes．This result may be a theoreti-cal support to the Korzhik_Turkin attack while explaining why the Adams—Meijer analy-sis to the McEliece'S cryptosystem conflicts with the real situation． |
