Problems solved by technology

However, in the architecture described in the patent, the nodes follow the rule of receiving the vaccine first and then verifying whether the vaccine is needed, which may cause the node to waste bandwidth on some redundant or erroneous data reception
Once the node receives the vaccine and cannot judge its reliability, it will send it to the server for judgment. However, the literature does not give a method for the server to judge the reliability of the vaccine; when the node sends the vaccine to the neighbor node, it is sorted according to the degree of connection. This can ensure that nodes with high connectivity will be immune faster, but at the same time, nodes with high connectivity will receive connection requests at high frequency, and the literature does not give the method of which request the node chooses

Embodiment Construction

[0049] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0050] as attached image 3 Shown, the present invention carries out vaccine distribution according to the following steps:

[0051] Step 1) constructs a double-layer Chord ring network; the double-layer Chord ring network includes two different node rings: a server ring and a lower layer node ring, wherein each node in the server ring is managing a corresponding lower layer node as a server ring, and is fully connected to all lower nodes in the lower node ring; the server nodes in the server ring and the lower nodes in each lower node ring use the Chord protocol for communication;

[0052] The basic structure of the Chord ring is attached figure 1 Shown, the structure of the two-layer Chord ring network that the present invention builds is as attached figure 2 shown;

[0053] For ease of understanding, assume that a certain server node SaSa in the...

Abstract

The invention discloses a vaccine distributing method based on a double-layer Chord ring network, belonging to the technical field of computer virus prevention and control. In the invention, the resource of non-server nodes in the network is fully utilized to increase the efficiency of vaccine distribution by constructing one compound double-layer Chord ring network, and the safety problem of vaccine transmission is solved by establishing a trust mechanism. Compared with the prior art, the invention efficiently reduces the load of a server.

Description

technical field [0001] The invention relates to the technical field of computer network antivirus, in particular to a vaccine distribution method. Background technique [0002] With the emergence and rapid development of Internet technology, the way of life of human beings has been greatly changed, but at the same time a large number of computer viruses have also appeared. It has also become an important part of computer network technology. [0003] In computer virus prevention and control methods, immunization is the most widely used method, and the most important thing is how to spread the vaccine to the entire network as soon as possible and cut off the transmission route of the virus. Most of the existing vaccine dissemination methods are server-client mode, that is, vaccines are distributed to all clients through a centralized server, and the vaccine dissemination speed is relatively slow, and the load on the server is too heavy. [0004] A Chinese invention patent ap...
