摘要：

Network coding can make the intermediate nodes encode the messages, and it has the merits of large network throughput, high resource utilization rate and strong system robustness. Traditional certificateless ring signcryption cannot be used in the network coding environment, so we construct one certificateless ring signcryption for multi-source network coding (MSNC-CLRSC), in which actual signcrypter can anonymously signcrypt a message on behalf of a group of users including himself. MSNC-CLRSC is provably confidential and unforgeable under the hardness of the co-decisional bilinear Diffie-Hellman and co-computational Diffie-Hellman problems in the random oracle model; moreover, it can resist the pollution attacks and has relatively low computation complexity.
