摘 要: | 为了减少证书管理的开销,基于身份的公钥密码体制在基于证书的公钥密码体制诞生后出现,并且越来越受到关注。针对椭圆曲线上的离散对数分离难问题,利用生物特征信息产生密钥数据,提出了一种基于生物特征身份的签名方案,确保信息传输的完整性和真实性,并对其安全性进行了分析。

Abstract: | Since the appearance of certificate - based public key systems, muclhattention has .een paid to identity - based public key cryptosystems to decrease the cost of certificates management. Based on the CDHP, biometric information was applied to construct the public key. While analyzing its algorithm and security, a biometric identity- based signature scheme was also proposed to guarantee its information transmitting integrity and reliability. |

Keywords: | identity - based fingerprint data bilinear map digital signature |
