Problems solved by technology

[0003] However, there are many security threats in the P2P network, such as Eclipse attack, which means that the attacker adds enough false nodes to the set of neighbor nodes of some nodes by occupying the routing table of the node, so that these nodes need to send When sending messages outside, there is a high probability that they are sending to false neighbor nodes. Invalid message sending increases and valid message sending decreases. In extreme cases, these nodes are "isolated" from the normal peer-to-peer network
[0004] If the above-mentioned P2P network attack exists in the P2P network adopted by the blockchain, the isolated nodes will not be able to broadcast and send messages normally, which will affect the normal operation of the centralized blockchain network

Embodiment 1

[0026] figure 1 It is a flow chart of a peer-to-peer network routing implementation method provided by Embodiment 1 of the present invention. This embodiment is applicable to the technical solution of message routing by setting multiple routing tables in the peer-to-peer network, and this technical solution is especially applicable In a weakly centralized peer-to-peer network, such as a blockchain network with specific identity nodes. The so-called weak centralization means that each node in the peer-to-peer network has different priority communication requirements in message communication due to differences in functional identities. The method can be executed by a peer-to-peer network routing implementation device, which is implemented by software and / or hardware, and is specifically configured in a computer device carrying a P2P network node.

Abstract

The embodiment of the invention discloses a routing implementation method and device for a peer-to-peer network, equipment and a medium. The method comprises the steps of determining at least one setidentity routing table through a node upper layer, wherein at least one node in the set identity routing table meets a set identity condition; deploying the set identity routing table in a routing layer of the node, the routing layer being further deployed in a basic routing table; and when a message sending demand is generated, sending the message in the peer-to-peer network based on the set identity routing table and the basic routing table. According to the routing implementation method for the peer-to-peer network, the influence of the network attack on the normal operation of the networkis reduced, the disgusting difficulty of the network attack is enhanced, and the stability of the system is further improved.

Description

technical field [0001] The embodiments of the present invention relate to routing communication technology, and in particular, to a routing implementation method, device, device and medium of a peer-to-peer network. Background technique [0002] P2P (Peer To Peer, peer-to-peer network) network communication is used in mainstream open source blockchain systems. The nodes in the P2P network discover the routing information of the neighbor nodes through the routing protocol and form a routing table. When a message needs to be sent, the destination node is selected and sent based on the routing table. For the blockchain network, nodes need to broadcast messages to the blockchain network, so they also need to send broadcast messages based on the routing information of neighboring nodes in the routing table. [0003] However, there are many security threats in the P2P network, such as Eclipse attack, which means that the attacker adds enough false nodes to the set of neighbor no...
