Embodiment Construction

[0021] Kademlia protocol, Kad is a distributed hash table (DHT) technology, through the unique XOR algorithm (XOR) as the distance measurement basis, a new DHT topology is established, which can greatly improve the routing query speed.

[0022] Kad has now become the mainstream implementation of DHT, and the p2p network that the Mozi botnet parasitizes is also based on Kad. The Kademlia algorithm is a distributed hash storage and routing algorithm. Each node of the P2P network based on the Kad protocol stores some resources.

[0023] In the p2p network built by the Kademlia protocol, all information is stored in the form of hash table entries, and these entries are scattered and stored on each node, thus forming a huge distributed hash table in the whole network.

[0024] node distance. The data key value (Key) and node ID (NodeID) in the Kademlia network are represented by 160 bits, and the NodeID is randomly assigned when joining the network. The Kad protocol stipulates th...

Abstract

The invention provides a relay routing pyramid data storage method, which is applied to a P2P network comprising a plurality of nodes, and comprises the following steps: step 1, constructing a pyramid storage model which comprises N storage hierarchies, N being a positive integer greater than 3; step 2, receiving a relay routing node set, and analyzing to obtain node IDs of relay routing nodes; step 3, obtaining the first eight bits of the node ID of the relay routing node as a parameter A, taking the first eight bits of the specific subtree prefix of the P2P network as a parameter B, performing XOR calculation on the parameter AB according to the bits to obtain f(AB), when f(AB) is greater than 0, calculating to obtain a storage level L(A)=(N-log2(f(AB)) of the relay routing node, and storing the relay routing node to an L (A) layer; otherwise, storing the node at the Nth level.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and device for storing relay routing pyramid data. Background technique [0002] In recent years, DDoS botnet family activities are still dominated by traditional IoT Trojan horse families represented by Mirai and Gafgyt. These traditional IoT Trojans develop new variants by adding new vulnerabilities and communication control methods. In this iterative process, new IoT botnets such as Mozi and BigViktor have emerged, further exacerbating the infighting situation among botnets. What's more serious is that the Mozi botnet targets Internet of Things devices with security vulnerabilities. With the rapid development of 5G and IoT, how to monitor and defend against such new botnets has become an important task to grasp the security situation of the Internet of Things and ensure the security of the Internet of Things. [0003] In addition, when processing data ...
