Machine-fixed multi-node integrated authorization management method

Abstract

The invention relates to a machine-fixed multi-node integrated authorization management method. The method comprises the following steps: (a) networking a fixed information service center and a plurality of maneuvering edge information service nodes; (b) performing identity authentication between the fixed information service center and the plurality of maneuvering edge information service nodes based on an identity authentication model improved by a Kerberos protocol; and (c) performing cross-node data transmission between the fixed information service center or / and the plurality of maneuvering edge information service nodes. Identity authentication between the fixed information service center and the plurality of maneuvering edge information service nodes is carried out by adopting an improved identity authentication model based on a Kerberos protocol so as to be used for cross-node data transmission, so that the security of identity authentication authorization is greatly improved.

Description

technical field [0001] The invention belongs to the field of network authorization, relates to a multi-node integrated authorization method, in particular to a machine-fixed multi-node integrated authorization management method. Background technique [0002] When managing cross-node data, the multi-node mobile information service center needs to realize the synchronous update of multi-node versions in view of the intermittent weak connection characteristics of specific environments, so as to solve the version consistency management problem caused by data distribution. In 2008, Tan Minghui analyzed and studied the incremental storage of versions. According to the characteristics of version control in process management, he proposed a process version incremental storage model that balances space efficiency and time efficiency, and proposed two conflicts: Solution: First, use the concurrency control method combining exclusive lock and authority management; second, version repli...

AI Technical Summary

Problems solved by technology

[0003] The existing process management version consistency methods mainly have the following problems: (1) non-real-time connection between edge information service nodes and between edge information service nodes and back-end cloud platform; (2) edge information service nodes often lack professional operation and maintenance personnel , do not have the experience and ability to operate and maintain complex information systems; (3) Due to the requirements of anti-destructive backup and random access, data needs to be distributed synchronously among multiple edge information service nodes, due to high network delay and network disconnection In other cases, there will be inconsistencies between the versions of multiple copies of a piece of data
