A p2p network resource sharing method and system

Abstract

The present invention discloses a P2P network resource sharing method and system. Each network node includes an area to be detected, a safe area and a suspicious area. The method includes generating a first list of resources in the safe area of ​​all nodes; judging the first list Whether it contains the requested resource, if so, prioritize the nodes containing the requested resource according to the security degree, and judge whether the congestion degree of the corresponding node is greater than the congestion threshold; according to the order of priority from high to low, the nodes without congestion Count the number, stop counting when the counted number is greater than the number threshold, and establish a connection between the counted node and the first node. A P2P network resource sharing method of the present invention sets a waiting area, a safe area, and a suspicious area for each node, which ensures that the nodes share resources, improves security, overcomes the limitation of the detection ability of a single node, and avoids False information provided by malicious nodes.

Description

technical field [0001] The invention belongs to the field of P2P networks, and in particular relates to a P2P network resource sharing method and system. Background technique [0002] Along with the advantages of P2P network, the efficiency of resource sharing is improved. But at the same time, because the P2P network is an open and unrestricted network, nodes are connected in a loose and free manner. In such an environment, it is easy to be attacked by various malicious codes, or receive false information provided by malicious nodes. [0003] Therefore, users should only download shared resources on nodes they trust, otherwise the security of resources cannot be guaranteed, thus violating the openness and cooperation originally proposed by P2P networks. Contents of the invention [0004] In order to solve the problems in the prior art, the present invention provides a P2P network resource sharing method and system. [0005] In the first aspect, the embodiment of the pre...
