Abstract |
|
|
| The signcryption scheme plays an important role in the applications which need privacy and authentication simultaneously. In order to get high efficiency in one-to-many communication environment and simplify the management of keys, a novel biometric signcryption scheme, identity-based and group-oriented, is proposed in this paper. In the scheme, the sender signcrypts the message and broadcasts it, but only the members of the receiver group can unsigncrypt the cipher text correctly. The implement of the scheme does not need bilinear pairing computation and modular exponentiation computation, hence it is very efficient. The analysis results show that the scheme is secure. |
