The existing ID-based signcryption schemes have some drawbacks, such as the signcryption can not be public verified, the signcryption can be forged, the signcryption is not robust, and etc. This paper analyzes the security of the LHL scheme and adopts the bilinear parings to propose an ID-based signcryption scheme. This scheme can ensure the signcryption has some characters, such as public verifiability, unforgeability, robustness, non-repudiation and forward security. It only needs four pairs of operation and it is more efficient than other ID-based signcryption schemes.
