Abstract

One or more embodiments in this application provide a method and device for constructing a heterogeneous and hierarchical anonymous communication network, including: obtaining the initial guard node and several guard nodes; constructing a guard ring of a ring path; selecting the aggregation to be constructed Several aggregation nodes of the ring, so that each aggregation node and other aggregation nodes generate a shared aggregation symmetric key; generate hierarchical encrypted data packets, connect the aggregation nodes according to the hierarchical encrypted data packets to build an aggregation ring of ring paths; generate aggregation rings using aggregation Aggregation and obfuscation messages encrypted with symmetric keys to protect messages on the aggregation ring; an anonymous communication network is constructed based on the information interaction between the aggregation ring and the guard ring, and the anonymous communication network is used to perform anonymous communication. This application can take advantage of the characteristics of different nodes, use the guard ring to protect the sender and receiver of the message, use the aggregation ring to prevent message leakage, and improve the anonymity of the overall network.

Description

technical field [0001] One or more embodiments in this application relate to the technical field of anonymous communication, and in particular to a method and device for constructing a heterogeneous and layered anonymous communication network. Background technique [0002] Anonymous communication implementation mechanisms in the prior art include: source rewriting technology-based, DC-Net problem-based and broadcast-multicast technology-based anonymous implementation mechanisms, wherein the anonymous communication network based on source rewriting technology consists of a series of forwarding nodes , the message is transmitted between the sender and the receiver through several intermediate forwarding nodes, and each forwarding node encrypts and decrypts the message, randomly delays it, etc., thereby hiding the address information, length information, etc. of the message. The existing anonymous communication network adopts the idea of ​​isomorphic design in the design of the...
