Anonymous communication path selection method and network node

The invention discloses an anonymous communication path selection method, which comprises the following steps that: an anonymous communication initiation node determines the number N of intermediate nodes in an anonymous communication path, and selects a node 1 from own adjacent nodes, wherein the node 1 belongs to a network area which is different from that with the initiation node; the same operation is repeated until a node N-1 selects a set number M of nodes from own adjacent nodes, and transmits the M nodes to the initiation nodes, and the initiation node selects a node N from the M nodes, wherein the node N belongs to a network area which is different from those with the node N-1 and all the nodes in the established anonymous communication path; and the node N establishes connection with a target node of anonymous communication. By the method, each node in the path can be ensured to belong to different network areas, and the security and reliability of the anonymous communication path are improved.
