Solution method for coping with information center network malicious content transmission

Abstract

The invention provides a solution method for coping with information center network malicious content transmission, and belongs to the technical field of communication. The method mainly comprises the steps that a user sends a request, a content provider replies with the content object, the content object verification nodes are decided, key nodes are verified, and the like. The malicious content provider follows the inverse path of an interest packet router to reply the user with a data packet. A middle node determines whether the data packet needs to be verified based on the verified node determining strategy, the to-be-verified nodes are decided, the node verification process is carried out, corresponding operation is conducted to the content object based on the verification result. According to the solution method for coping with information center network malicious content transmission, the router mode based on the content is used for making the middle router able to verify the content target to find out fake content as soon as possible, and stop the transmission of the fake content to the downstream, therefore the squandering of internet resources caused by the transmission of fake content is avoided. The method can guarantee the service quality. At the same time, the computation burden of the nodes in the internet is alleviated, and the time delay caused by multiple nodes obtaining secret keys.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a segmentation forwarding strategy of content objects in a content-centric network. Background technique [0002] Information-Centric Networks (ICNs) is an important part of the future network. ICN aims to establish a simple, general and flexible communication architecture, which is content-centric rather than host-centric. ICN is more concerned with the content itself rather than the geographic location where the content is stored. One of the typical features of ICN is the built-in cache of the network. High-speed storage devices are deployed on the router to cache some content objects in the network. When the user requests the cached content, the router will directly reply the content to the user without requesting the upstream content provider. In this way It can shorten the time for users to obtain content and improve QoS. Content-Centric Networking (CCN) is one of the ...

Problems solved by technology

[0005] ①The network cannot provide correct content, causing users to repeatedly send requests for the same content, resulting in waste of network resources and even congestion;

[0006] ②The network cannot provide correct content for a long time, which will greatly reduce the service quality of the network and lead to the loss of customer sources

[0008] ①Consumers are busy verifying the signature of false content, and the resources on the consumer side are seriously consumed;

[0009] ②Consumers have repeatedly obtained false content, which greatly reduces user experience

[0013] The above two schemes have their own advantages and disadvantages. Since all the data packets passed through the network verification are not desirable at least in the CCN system discussed so far, we propose a compromise scheme, the key node verification scheme
