自2003年Al-Riyami和Paterson首次提出无证书公钥密码体制的概念和第一个无证书签名方案以来,许多无证书签名方案相继被提出。汤永利等提出了9个无双线性对运算的无证书签名方案,并声称这些无证书签名方案在椭圆曲线离散对数困难性假设下可证明是安全的。通过对这些无证书签名方案进行安全性分析后,发现其中的5个可证明安全的无证书签名方案不能抵抗替换公钥攻击,并且这5个无证书签名方案中的3 个签名方案即使在不替换用户公钥的情况下,攻击者也可以利用用户的原始公钥对任意消息伪造出有效的签名。给出了具体的伪造攻击方法,证明了这5个无证书签名方案是不安全的。
Since Al-Riyami and Paterson proposed the novel concept of certificateless cryptography and the first certificateless signature scheme in 2003
a lot of certificateless signature schemes were proposed one after another.Recently
Tang et al proposed nine certificateless signature schemes without bilinear pairing.Although they demonstrated that their schemes were unforgeable under the assumption of elliptic curve discrete logarithmic problem
it can be found that five of their schemes could not resist the public key substitution attack
the attacker could use the user's original public key to forge a valid signature for three of these schemes.The attack methods are to demonstrate that prove five certificateless signature schemes are insecure.
