在离散对数问题的困难性假设下,提出了基于证书签名方案,并在最强的安全模型下证明了该方案的安全性.该方案只使用普通的Hash函数,其签名算法和验证算法都不需要复杂的双线性对运算,计算效率高,适用于无线传感器网络等能量受限的系统.
Under the difficult assumption of discrete logarithm problem, this paper proposes a certificate-based signature scheme and proves the security of the scheme under the strongest security model. The scheme only uses the ordinary Hash function, and both the signature algorithm and the verification algorithm It does not require complicated bilinear pairing calculation and has high computational efficiency. It is suitable for energy-limited systems such as wireless sensor networks.
