Anonymous communication method, system and device based on internet file storage service

Abstract

The invention discloses an anonymous communication method, system and device based on an internet file storage service, and the method comprises the steps: achieving the hiding of a user identity anda communication relation through a large number of user groups and access behaviors of an internet public file storage service; and using an internet public file storage service platform as an intermediate node for information forwarding, storing communication content in a data exchange file according to a specific file format, exchanging files between two communication parties in an asynchronouscommunication mode according to an agreed file exchange protocol, and achieving anonymous communication. The complete communication process comprises identity registration of a communication user, construction of a data exchange file by a sender, sending of the data exchange file by the sender, receiving of the data exchange file by a receiver, restoration of the data exchange file by the receiverand response of a communication result. The method, the system and the device can reduce the cost, guarantees the safety of communication contents and the anonymity of communicators and communicationrelationships, and can be widely applied to the technical field of network communication.

Description

technical field [0001] The present invention relates to the technical field of network security communication, in particular to an anonymous communication method, system and equipment based on Internet File Storage Service (IFSS). Background technique [0002] The existing anonymous communication systems are represented by Tor and I2P. Although the communication technology based on content encryption can protect the anonymity of the communicator and the communication relationship, most of these systems can only allow information to be distributed in a dedicated network composed of specially built nodes. transmission, which can lead to a series of problems. For example, building a private network requires a large amount of cost to purchase a large number of servers and bandwidth resources. If the budget for purchasing servers is low, it will not be possible to provide enough nodes to cover the identity of participants in anonymous communications, while a low bandwidth budget ...

Problems solved by technology

[0002] Existing anonymous communication systems are represented by Tor and I2P. Although the communication technology based on content encryption can protect the anonymity of communicators and communication relationships, most of these systems can only allow information to be distributed in a dedicated network composed of specially built nodes. transmission, which can lead to a series of problems

For example, building a private network requires a large amount of cost to purchase a large number of servers and bandwidth resources. If the budget for purchasing servers is low, it will not be possible to provide enough nodes to cover the identity of participants in anonymous communications, while a low bandwidth budget will lead to poor communication quality. good

However, it takes a lot of time to build and disassemble a large-scale network that can provide sufficient anonymity, and it is easy to attract attention

At the same time, these existing anonymous communication systems are often based on IP flow protocols, exchanging information among nodes with similar behaviors, usually with low asynchronicity and obvious time characteristics; the communication method is single, the data packet characteristics are obvious, and are easy to be identified by attackers. The problem is even more serious in the context of the reality of machine learning algorithm-assisted traffic identification
