Topological information confusion method and device with hidden key nodes and computer equipment

The invention relates to a key node hidden topological information confusion method and device and computer equipment, and the method comprises the steps: carrying out the topological structure speculation of a to-be-protected real network through employing a topological structure measurement method which will be employed by an attacker, and obtaining a speculated topological structure; key nodes in the speculative topological structure are identified and hidden to obtain a false confusion topological structure, a corresponding false shared link matrix is obtained, and the false shared link matrix is input into a delay strategy model to obtain an optimal false link time delay vector; and obtaining a false path delay vector of the false confusion topological structure according to the false shared link matrix and the link delay vector, finally obtaining a delay strategy according to the false path delay vector and the delay vector of each path in the real network, and arranging nodes in the real network accord
