Network coding allows intermediate nodes to encode data packets to improve network throughput and robustness. However, it increases the propagation speed of polluted data packets if a malicious node injects fake data packets into the network, which degrades the bandwidth efficiency greatly and leads to incorrect decoding at sinks. In this paper, insights on new mathematical relations in linear network...
Network coding allows intermediate nodes to encode data packets, which increases network throughput and enhances robustness. However, once a node injects corrupted data blocks into a network, the polluted data blocks will propagate quickly with network coding. Based on linear subspace and key pre-distribution, this paper proposes a HYBRID scheme against pollution attacks to network coding. Some typical...
