Method and device for key group scattered management

Abstract

The present invention discloses a method and device for key group scattered management, including constructing a scattered network, dividing the scattered network into several scattered subnets in a grouping manner, and according to the client nodes received by the server, according to the scattered network Security level and subnet member scale status judge whether to add new nodes to open up new groups and generate group information, add the newly generated client node information and group information to the addressing table, and feed back some fields to the client nodes; choose scattered scheme, exchange and store keys between different client nodes; when a client node reads data, the server finds the node that stores the client key according to the scattered scheme and addressing scheme, and returns the key to the client, and then Decryption reads the data.

Description

technical field [0001] The invention relates to the technical field of key management, in particular to a method and device for key group scattered management. Background technique [0002] Nowadays, more and more important information and data are transmitted in the Internet. The key is the security guarantee for the confidentiality of important information and the authenticity of the data. However, key security management is the most intuitive and important link to realize the security guarantee. Among the huge number of Internet users, users without professional technical background account for a very large proportion. For this part of users, it is generally impossible to safely manage the keys they hold. Therefore, how to implement secure key management at low cost is the focus of most users. [0003] At present, common users use local storage or hand over to a third-party platform to securely manage the key. Due to the lack of professional management means, the securi...

AI Technical Summary

Problems solved by technology

Due to the lack of professional management means, the security of the key stored locally by the user is very low, and the possibility of being stolen is extremely high

Secondly, if it is managed by a third-party platform, users do not have the ability to identify and judge in terms of the credibility of the platform and the effectiveness of management

In addition, third-party platforms are risk-aggregating. Once the platform fails or data is leaked, the losses caused will be unimaginable
