Embodiment 1

[0042] In this embodiment, we propose a new and improved method to realize the central authorization control function in the P2P transmission process in the non-centralized directory mode.

[0043] For the P2P file transfer mode of the non-centralized directory mode, that is, multiple nodes (Peers) of the group do not use the central directory server, but use a full peer-to-peer structure: each node records the IP addresses of multiple other nodes, Breadth-first or depth-first search is carried out by covering the network. After a certain range is searched, the result matching the search condition is returned to the user, and the file is directly exchanged between two nodes (Peers).

[0044] A device for performing central authorization control in P2P file transmission in this embodiment includes a plurality of nodes composed of multiple client computers participating in P2P file transmission, and the nodes perform data interaction through a communication network, Each client ...

Embodiment 2

[0082] In this embodiment, we propose a new and improved method to realize the central authorization control function in the P2P transmission process of the centralized directory mode.

[0083] The difference between this embodiment and Embodiment 1 is that a device for performing central authorization control in P2P file transmission in this embodiment also includes a central directory server used by multiple nodes, and the central directory server includes a single or multiple CPUs and memory devices, and the central directory server performs data interaction with each login node through a communication network.

[0084] As shown in Figure 3, a kind of method for central authorization control in the P2P file transmission of this embodiment comprises the following steps:

[0085] Step 1: Node A logs in to the ticket server;

[0086] Step 2: Node A logged in to the ticket server generates a pair of temporary keys (public key Ktu+private key Kti);

[0087] Step 3: The ticket ...

Abstract

The present invention provides a novel device for doing central authorization controlling in the transmission of the P2P document and the control method, which settles the problem that the authority of the transmitter can not be controlled in the transmission of the P2P document. Thereby administer is allowed to has the ability of restricting the accessing by the non-authorized user to the sharing document of other person. In the invention the device which does central authorization controlling in the transmission of the P2P document includes a plurality of crunodes which are composed of a plurality of client terminal computers that participate in the transferring of the P2P file, the crunodes does data alternation with the communication network, and each customer end computer includes an input device, a display device and a computer mainframe which are connected together; wherein: the device which does central authorization controlling in the transmission of the P2P document is provided with a bill server that does authorization to the transmission of each crunode and controls the document transmitting content, the bill server includes a single or a plurality of CPUs and internal memory equipment, and the bill server does data alternation to each crunode with the communication network.

Description

technical field [0001] The invention relates to computer data transmission control technology, in particular to a device and method for central authorization control in P2P file transmission. Background technique [0002] P2P technology is a technology that uses distributed resources in a non-centralized manner to complete key tasks. Different from the computing technology of the previous client / server model, the object of providing resources is not only certain servers, but on the contrary, each node has the same status, has the dual characteristics of client and server, and can serve as a service at the same time users and service providers. In the file transfer application of the Internet, the use of P2P technology can effectively reduce the transfer load of the server and improve the speed when users download a large number of files. However, due to the distribution and anonymity of P2P technology itself, it is difficult to implement effective authorization control whe...
