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. </span>

In recent years, the secret place’s frequency occurrence of leaks has brought huge economic losses on the national security、 social stability and economic life, which not only seriously harmed the national interest, but also raised a range of negative social impacts. Therefore, implementing effective monitoring strategies to protect the secret place is of great significance. In the paper, the wireless short-range communication technology ZigBee was adapted to design a wireless monitoring system, the short-range communication technology ZigBee can network quickly and has many monitoring terminals, so it can monitor the equipments and materials, persons and the environment in the building and protect the security of buildings from the source.
