摘要: 针对一种基于身份一次性公钥的构造方案给出2种攻击方法,指出其是可伪造的。基于超奇异椭圆曲线并利用一般椭圆曲线签名算法对基于身份的一次性公钥方案进行重新构造,新的构造方案能够抵抗伪造性攻击,是安全高效的。由于用户每次可以使用不同的公钥,方案可用于解决Internet通信中的匿名认证问题,实现用户隐私的有效保护。

Abstract: Aiming at the construction scheme of the one-off public key, this paper proposes two attack forgeries, and indicates that their schemes are universal forger. It proposes a new construction of one-off public key, which is based on the super singular elliptic curve and only utilizes common elliptic curve digital signature algorithm. The scheme is robust against the two attack forgeries, with perfect security and high efficiency. As user’s public key is different every time, it can be applied to implementing Internet anonymous attestation for privacy protection.

Key words: anonymous attestation, one-off public key, bilinear pairing, elliptic curve signature algorithm
