The invention discloses a credible routing method based on network coding, which comprises the following steps: allowing a key node of a network to carrying out the network coding; transmitting a packet on a link with high trust level after carrying out coding on the packet; and obtaining a packet lost in a link with low trust level through decoding at an intersection node of the route. The coefficient of the network coding is generated by a specific matrix provided by the invention, so the problem of difficult decoding in the existing network coding method can be solved, and the success rate of decoding can be ensured. Through the model of coordination transmission of the link with high trust level and the link with low trust level, the invention not only avoids network congestion, but also effectively solves the problem that the link with low trust level losses the packet, reduces the transmission delay, and has important practical value in the actual communication network route.
