| Abstract | Biometric signcryption, which enables a user using his biometric information as the identity to fulfills both the functions of encryption and digital signature simultaneously, and it provides better overall security and performance. However, almost all biometric signcryption schemes that have been proposed in the literature do not satisfy forward secrecy, known session-specific temporary information security and public verifiability with confidentiality, also have the certificate management complexity or key escrow issues which are inherent in traditional public key and identity-based cryptography respectively. In order to solve these problems, a novel biometric signcryption using certificateless public key cryptography is introduced, the formal definition and security notion of the biometric certificateless signcryption (BCSC) are presented, and a concrete BCSC scheme is also proposed in this paper. The proposed scheme eliminates the above security shortcomings and it does not have the certificate management complexity and key escrow issue by exploiting the certificateless public key cryptography. Moreover, the proposed scheme only requires one bilinear pairing operation, which makes it applicable to the resource-constrained communication devices and the communication networks with high security requirements. |
