Embodiment Construction

[0076] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0077] This application is mainly applied to anonymous communication scenarios, such as figure 1 A schematic diagram of an application scenario shown. It can be seen that communicator A and communicator B need to communicate. In the environment of anonymous communication, the communicator A communicates the communication data with the terminal B of the communicator B through the terminal A. At this time, if the communicator A and the communicator B are in an ordinary communication environment, it is very easy for a network attacker to obtain the routing path, so as to determine the identity information of the communicator A and the communicator B. In an anonymous communication environment, network attackers usually cannot obtain the identity information of communicator A and communica...

Abstract

The embodiment of the invention relates to a decentralized anonymous communication system. The decentralized anonymous communication system comprises a plurality of network nodes and a structured point-to-point network formed by the network nodes. Wherein each network node is internally provided with a trusted operation environment, and the system operates in the trusted operation environment. The first communication node sends the first communication data to the anonymous communication secret exchange node according to the first routing table, and the second communication node sends the second communication data to the anonymous communication secret exchange node according to the second routing table; and the anonymous communication secret exchange node sends the first communication data to the second communication node according to the third routing table, and sends the second communication data to the first communication node. According to the method, anonymous communication is performed through the network nodes running in the trusted running environment, and the anonymous communication secret exchange node is adopted between the two network nodes as the network node for data exchange, so that Dos attack and active flow analysis attack can be resisted, and the security of a communication system is guaranteed.

Description

technical field [0001] The present application relates to the field of communication, and in particular, to a decentralized anonymous communication system, method and device with low latency, high reliability and strong privacy protection. Background technique [0002] At present, people want to use a communication system that can ensure the confidentiality of messages and the anonymity of users while ensuring the quality of communication. Confidentiality means that the content of the sent message cannot be known by others. Therefore, only by guaranteeing confidentiality can personal privacy not be disclosed. Anonymity means that the identities of the communicating parties cannot be obtained by the outside world. In most scenarios, users do not want to reveal who they are communicating with. Obviously, only by guaranteeing anonymity can a large number of relatively confidential online applications (applications, APPs) be supported, such as bitcoin transactions. Therefore, ...
