| Abstract: | Based on network coding,a packet filtering scheme against entropy and pollution attacks was presented, which can be used test the linear dependency of received data packets and determine the non-innovative packets according to the testing results,and then detect and eliminate polluted packets,thus preventing malicious behaviors.The analytical and experimental results showed that the scheme is secure and can rapidly improve throughput and transmission efficiency and decrease network load. |
