Anonymous signcryption is a novel cryptographic primitive motivated from ring signature. It is an important method to realize the signcrypter identities' ambiguity. In this paper, we propose an identity-based anonymous signcryption scheme for multiple receivers in the standard model. The proposed scheme satisfies the semantic security, unforgeability and signcrypter identity's ambiguity. We also give the formal security proof on its semantic security under the hardness of Decisional Bilinear Diffie-Hellman problem and its unforgeability under the Computational Diffie-Hellman assumption.
