Abstract

One or more embodiments of the invention provide a heterogeneous layered anonymous communication network construction method and device. The heterogeneous layered anonymous communication network construction method comprises the following steps of: acquiring an initial guard node and a plurality of guard nodes; constructing a guarding ring of an annular path; selecting a plurality of aggregation nodes of an aggregation ring to be constructed, and enabling each aggregation node and other aggregation nodes to generate a shared aggregation symmetric key; generating a hierarchical encryption datapacket, and connecting the aggregation nodes according to the hierarchical encryption data packet to construct an aggregation ring of an annular path; generating an aggregation confusion message encrypted by using the aggregated symmetric key to protect the message on the aggregation ring; and constructing an anonymous communication network based on information interaction between the aggregationring and the guarding ring, and executing anonymous communication by utilizing the anonymous communication network. According to the heterogeneous layered anonymous communication network constructionmethod and the device, properties of different nodes can be exerted, the guarding ring is used for protecting a sender and a receiver of the message, the aggregation ring is used for preventing message leakage, and the anonymity of the whole network is improved.

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...
