Abstract: In order to solve the application unsecure problems for provable secure encryption scheme of random oracles model, an identitybased multireceiver signcryption scheme (IBRSC) under standard model was proposed. In the IBRSC, identitybased encryption algorithm and multireceiver signature algorithm were combined with bilinear pairing on elliptic curves to form the ID-based signcryption scheme for multiple receivers scheme and security concept. A new secure, efficient identitybased multireceiver signcryption scheme was proposed. The signcryption scheme was proved to be secure against adaptive chosen ciphertext attacks and adaptive chosen message attacks based on decisional bilinear Diffie-Hellman assumption and computational Diffie-Hellman assumption, respectively. The results show that the proposed scheme is fully secure without random oracles, and can efficiently improve the security of multireceiver network and reduce computing consumption of bilinear pairing.
