摘要： 针对基于单一生物特征身份的签名方案在实际应用中存在的问题，提出一种基于多重生物特征身份的签名方案，研究基于椭圆曲线的n-挠群，对不同生物特征进行融合，介绍基于生物特征身份的公钥密码体制，仿真实验结果表明，该方案在安全性、稳定性以及可靠性等方面，均具有一定优越性。

Abstract: Aiming at problems in practical application of single biometric identity-based signature scheme, a novel multi-biometric identity-based signature scheme is proposed. The elliptic curve-based n-torsion groups are researched. Different biometric characteristics are syncretized. The biometric identity-based public key cryptosystem is introduced. Simulation experimental results show this scheme has better performances in security, stability and reliability, and is effective and feasible.

Key words: n-toison group, public key cryptosystem, digital signature
