It is important to improve the efficiency of identity-based multi-signcryption schemes.There already have some schemes proposed.In this paper, we present an efficient identity-based multi-signcryption scheme which uses the bilinear pairing on elliptic curves and combines identity-based encryption algorithm with the multi-sender signature algorithm.We firstly present the framework of identity-based multi-signcryption schemes, then proved the correctness and analyzed the security and the computational efficiency of the new scheme in standard model.The results show that when the number of signcrypters is n (n>1), the new scheme reduced by n-1 exponentiations is a safe and more efficient multi-signcryption scheme.
