Security access control method for three-dimensional database of power grid engineering under high concurrent access

Le résumé fourni par la source

In order to reduce the avalanche effect value during secure access to the three-dimensional power grid engineering database and improve access throughput, this study designed a database security access control method for high-concurrency environments. Firstly, thread pool technology was introduced to implement user identity authentication in high-concurrency access scenarios. Secondly, based on the zero-trust principle, a secure access permission allocation architecture was designed to dynamically assign user access permissions by calculating user trust values, three-dimensional data quantification values and permission decision values. Finally, blockchain technology was employed to generate secure access control contracts. Experimental results demonstrate that after applying this method, the maximum avalanche effect value of the three-dimensional power grid engineering database was only 0.50, while the maximum database throughput reached 340 Tps.
