Secure storage algorithm based on dynamic election and consensus mechanism

Abstract

The invention relates to the field of data storage security, particularly to a secure storage algorithm based on dynamic election and a consensus mechanism. An initial node is calculated and stored byrunning a security consensus service SCS; a security consensus area SCA basis of data storage is formed, and a security consensus service SCS realizes six mechanisms. The system comprises a securityauthentication mechanism SAF, a security communication mechanism SCF, a security election mechanism SEF, a security storage mechanism SSF, a security recovery mechanism SRF and a threat detection mechanism TMF. The security authentication mechanism SAF is called to identify and authenticate the legality of the new request joining node, the legal node is allowed to join a security consensus area SCA, and the security communication mechanism SCF is called to configure the node in the security consensus area SCA; according to the technical scheme provided by the invention, the defects that the security of the newly added node cannot be ensured and a security consensus mechanism cannot be established between the newly added node and the existing node in the prior art can be effectively overcome.

Description

technical field [0001] The invention relates to the field of data storage security, in particular to a security storage algorithm based on a dynamic election and consensus mechanism. Background technique [0002] In the current distributed and peer-to-peer communication technology, in order to increase the utilization and efficiency of data storage space, through the establishment of a peer-to-peer mechanism for storage nodes, nodes with computing capabilities can join the storage system as long as they run specified services and abide by specified communication protocols. , and can communicate with other data storage nodes. Although this method improves the efficiency and speed of data interaction, the security risks brought by joining nodes may lead to data being stolen by malicious nodes. At the same time, key nodes face the threat of potential attacks and the risk of losing control rights. [0003] Aiming at the above problems, a security consensus area algorithm based ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides a secure storage algorithm based on dynamic election and consensus mechanism, which can effectively overcome the inability to guarantee the security of newly-joined nodes in the prior art, and the relationship between newly-joined nodes and existing nodes. There is a defect that nodes cannot establish a secure consensus mechanism
