摘要 在椭圆曲线中的GDH群上,利用B-DH难解假设和安全的双方计算协议,构造了一种新的高效指纹匿名方案.由于方案是基于椭圆密码体制的,因而具有较短的密钥.另外,双线性映射保证了运算的高效性. In the gap Diffie-Hellman group, based on the bilinear Diffie-Hellman intractable assumption and the security two-party computation protocol, a new efficient anonymous fingerprint scheme is proposed. This scheme is not only short in key size due to the use of the elliptic cryptosystem, but also efficient in computation because of bilinear mapping.
