Signature Scheme in Eisenstein Ring Based on Multi-Biometric Characteristic Identity
Feng Li, Qingzhen Xu · 2016
In order to implement a secure and effective curves cryptosystem, a signature scheme for conic curve over Eisenstein ring is given. The security is based on the difficulty in computing discrete logarithm on Abel group Cr(a, b). Because of the limitations of single biometric identity-based signature scheme used in practical application, a multi-biometric identity-based signature schemes is proposed. This paper introduces a biometric-based key generation technology "fuzzy extractor", in which different biometric characteristics are aggregated. The research finds that it is easy to embed plaintext, implement and secure reliable.
