Abstract

One or more embodiments of this specification provide a user node anonymous communication method and device, which can ensure the security of user node anonymous communication. The method includes: obtaining network node information, selecting a plurality of guard nodes from the network nodes; establishing a ring communication connection between the user node and the guard nodes, forming a ring including the user node and all the guard nodes The ring path is used to exchange information with the nodes outside the ring. The device includes: a node selection module, a path creation module and an information interaction module.

Description

technical field [0001] One or more embodiments of this specification relate to the field of information security technology, and in particular, to a method and device for anonymous communication between user nodes. Background technique [0002] Network anonymous communication is a privacy protection technology that uses measures such as message forwarding, data encryption, and traffic obfuscation to hide communication content and relationships. Network anonymous communication technology is mainly used in anonymous e-mail system, anonymous network storage system, anonymous publishing system, anonymous Web browsing system, etc. [0003] From the perspective of implementation mechanism, the basic implementation mechanism of network anonymous communication mainly includes the following three types: the anonymous implementation mechanism based on source rewriting technology, based on DC-Net problem and based on broadcast and multicast technology. Among them, anonymous technology...
