摘要: 证明了2003年邓仰明等提出的一种数字签名方案存在安全漏洞:任何人仅利用签名用户的公钥就可以破译部分私钥,从而成功地实现伪造签名。然后指出具有类似公钥构成的数字签名体制都可以仅凭借公钥获取部分私钥。

关键词: 数字签名, 纠错码, 密码分析

Abstract: The existence of a security leak in a digital signature scheme proposed by Deng Yangming in 2003 is proved.It is shown that in this digital signature scheme anyone can obtain partial secret key just by resorting signatory’s public key,therefore,he may successfully forge a signature.Then it is pointed out that anybody can achieve partial secret key just by employing public key in the digital signature schemes whose design of public key is similar to the above proposed scheme.

Key words: digital signature, error-correcting codes, cryptanalysis
