Method for implementing IP credible route based on fault-tolerance and invasion-tolerance

Abstract

The invention discloses a method for realizing an IP credible route based on fault tolerance and intrusion tolerance, comprising the following steps: (1) when a data packet is transmitted to a node, the node is taken as a transmitting node which selects a receiving node to deliver the data packet, and then the receiving node carries out detection through trust detection and a trust extension route table; if the detection fails, the data packet delivery fails and step (2) is carried out; if the detection succeeds, the receiving node receives the data packet and a route is established successfully; and (2) routing recovery for the data packet which can not be delivered successfully is carried out. The realization process of the IP route is safe and credible; when a network encounters vicious attacks or breaks down, communication can be recovered quickly on the premise of minimum resource consumption; moreover, the method can eliminate damages to a network route caused by decrial attacks, two-faced behavior attacks, intermittent attacks and node failures, and has better fault-tolerant and intrusion-tolerant capability.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a fault-tolerant and intrusion-tolerant IP trusted routing implementation method. Background technique [0002] With the continuous development of computer network technology and the wide application of network, more and more attention has been paid to the security issues in network communication. People hope that the network can still provide normal services even when it fails or suffers malicious attacks such as viruses. Among them, the implementation method of trusted routing in IP network has also become a hotspot of extensive research. Trusted routing is an important idea in secure routing. It draws on the trust relationship in the human social network and applies it to the communication field to establish a "trust relationship" between routers. Whether it is their own errors or malicious behaviors, whether they use "trust" to decide whether to "communicate" with th...

Problems solved by technology

The disadvantages are: (1) It assumes that the watchdog mechanism only monitors adjacent nodes, which greatly simplifies the design of the watchdog mechanism, but it does not fully share the trust information between nodes

Therefore, the interaction of trust values, that is, the implementation algorithm of IP trusted routing is also crucial; (2) the watchdog mechanism does not precisely define the part of the decision module; (3) although the design of RFEN takes into account The aging problem of trust value, and define the aging weight to alleviate this situation, but there are still deficiencies
