| Abstract | Network coding substantially improves the throughput of a network and possesses security superiority, but the security and performance of a network coding based wireless network are highly susceptible to malicious attacks such as pollution attack, dropping attack, lack of cooperation and selfish nodes collusion. This paper designs a secure network coding scheme that works in an adversarial environment, which can resist pollution attack, decrease the compromising probability of the message, and achieve tradeoff between security and performance by integrating the multipath and optimizing the coding packets allocation. Meanwhile, it also improves the fault tolerance of link failure or dropping attack by adding the finite redundancy coding packets. In addition, considering the selfish nodes of noncooperation communication, we design an incentive compatible protocol to stimulate forwarding packets and prove that only following the protocol honestly can obtain maximum utility. Furthermore, it is also proved that there is no collusion that can profit all colluding players. Finally, the simulation evaluation and security analysis confirm our theoretical results. |
