The invention aims at defense and protective problems in complex network safety, and discloses a complex network protective method oriented towards adding of protective links of key nodes. The complex network protective method is based on that original network connection is kept unchanged, utilizes the theory of building key balancing rings and key chains, and utilizes the strategies that the key balancing rings are built around the key nodes and key protective links are added among the key nodes. By means of the complex network protective method, a part of flow originally passing through the key nodes bypasses the key nodes, network loads tend to be balanced to a certain degree, jamming of the key nodes is effectively relieved, reliability and fault-tolerant capability of a network are improved, and the complex network protective method achieves good defense and protective effects on calculated attacks and high-load attacks in the complex network.
