摘要：
Hybrid signcryption can process the messages of arbitrary length, while public key signcryption cannot. In this paper, we extend hybrid signcryption technique to the certificateless setting, and construct a provably secure certificateless hybrid signcryption (PS-CLHS) scheme. In the random oracle model, we prove that the proposed scheme satisfies the indistinguishability against adaptive chosen-ciphertext attacks and unforgeability against adaptive chosen-message attacks under the hardness of the bilinear Diffie-Hellman problem and computational Diffie-Hellman problem. In addition, this scheme has lower computational complexity and is appropriate to applications in practice. ©, 2015, Science Press. All right reserved.
