Abstract

The invention discloses a method and a node for storing and routing data in a peer-to-peer (P2P) network on the basis of the node bottom layer security level. The method comprises the following steps of: determining the corresponding relation between the importance level of the data and the node bottom layer security level, and storing the key word level of the data into the node with the corresponding node bottom layer security level according to the importance level and the corresponding relation; and when the data is searched, searching the data in nodes with the same node bottom layer security level as the node in which the data is stored.

Description

technical field

[0001] The invention relates to the field of computers, in particular to a data storage and routing method and node in a P2P network based on a node bottom security level in a peer-to-peer (Peer to Peer, referred to as P2P) network. Background technique

[0002] In related technologies, the security of the P2P network has received more and more attention, but the research on the security of the P2P upper layer (Overlay) network is mostly limited to the Overlay layer itself, that is, the main research is due to the behavior characteristics of the Overlay itself. Multiple security threats and defenses. Since the Overlay network is built on the Underlay network, the nodes that make up the Overlay network are bound to be affected by infrastructure conditions such as operating systems and network protocols. That is to say, a trusted node on the Overlay layer may have weak security performance on the Underlay layer, making it easy for attackers to attack the node ...

Examples

Embodiment Construction

[0018] In order to solve the problem of how to implement the security defense mechanism scheme integrating Overlay and Underlay on the Overlay of the P2P network in the prior art, the present invention provides a data storage and routing method and a node in a P2P network based on the underlying security level of the node. The invention provides a specific realization of the security level division mechanism integrating overlay and underlay based on the underlay security level division mechanism in the P2P network, and improves the overall security of the P2P network on the basis of changing the original P2P network storage and routing mechanism as little as possible. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to illustrate the present invention, but not to limit the present invention.
