Certificateless Homomorphism Network Coding Signature Scheme

As an information transmission technology, network coding can reduce the transmission delay and improve the transmission efficiency with network performance. However, the nodes in network are vulnerable to the pollution and forgery attacks. Until now, most of network coding schemes are from pairing. Under the requirement of low computation complexity, we construct certificateless homomorphism network coding signature scheme (CL-HNCSS). In CL-HNCSS, certificateless technology avoids key management and key escrow for multi-source nodes, the homomorphism and scalar multiplication are used to reduce the computation cost. CL-HNCSS satisfies the unforgeability under the adaptive chosen-message attacks and can resist the pollution attacks. In addition, CL-HNCSS has very high communication and computation efficiency.
