Trusted improvement method of router

Abstract

The invention provides a trusted improvement method of a router. Mainly targeting on the trust value carried by a ToS (type of service) field (IPv4) or a TC (traffic class) field (IPv6) in the header of an IP (Internet protocol) packet and the source of the IP packet, the method can carry out the dynamic adjustment on the trust value under the guidance of the trust strategy and lead the router to carry out the related operations of packet classification, enqueueing management, queue scheduling and packet loss regulation according to the trust value, so as to give the first priority for the guarantee of the transmission reliability and rate of more trusted IP pockets in the network and actively delay or drop the packets with lower trust value to confront the potential unsafe factors, such as network congestion and attack, thus making the entire network more trusted and safer.

Description

technical field [0001] The invention relates to the field of communication security of IP networks, in particular to a scheme for trusted transformation and flow control of routers. According to the trust value information carried in the header field of the IP data packet in the IP network, the method performs marking, classification, queuing and necessary packet loss operations on the IP data packet in the network, so as to ensure the security and credibility of the network. Background technique [0002] With the increasing research on trust, especially trust management technology, network security is developing in the direction of network trustworthiness. In the future, network security is a trustworthy network that increases behavioral trustworthiness. This is also a new consensus in the field of network security research in recent years. . Trust management technology tries to achieve the same level of trust as traditional interaction means through network interaction th...

AI Technical Summary

Problems solved by technology

[0003] At present, the research on trust management technology is still only at the stage of modeling and optimization, and there is no more realistic scheme and implementation of trust management infrastructure to meet the security and trust requirements of the network.

Especially for the router, the most important physical connection device in the network, there is currently no scheme to apply the new research direction and idea of ​​trust management to the router to ensure the security and trustworthiness of the network during connection and transmission.
