An Online Certificate Status Query Method Based on Limited Priority Dynamic Scheduling Grouping Algorithm

Abstract

The invention provides the technical scheme of an on-line certificate state query method for a dynamic packet scheduling algorithm on the basis of a limited priority level. The scheme is based on the limited priority level dynamic packet scheduling algorithm; when a CA (certificate authority) center issues an updated-state digital certificate, the algorithm is utilized to dynamically group and store the updated digital certificate into a CA database, and a characteristic identifier is correspondingly added; and when the digital certificate state is queried, the characteristic identifier is matched to look up the priority level group corresponding to the digital certificate to obtain the real-time state of the digital certificate. According to the method, the query time of the data base is reduced, the query time is shortened, the query efficiency is improved, and the on-line certificate state query method has a good applicability for the financial stock exchange and the bank in which the effectiveness of the digital certificate is frequently verified and the state of the digital certificate changes frequently.

Description

technical field [0001] The invention relates to a database classification query method, in particular to an online certificate status query method based on a limited priority dynamic scheduling grouping algorithm. Background technique [0002] In the prior art, the known technology is that with the continuous development of e-commerce, transactions based on electronic networks are becoming more and more frequent. Since e-commerce completes transactions through the Internet, there is no need for face-to-face transactions between transaction parties. Realize fast and accurate two-way data and information exchange. However, the security and reliability of e-commerce has always been a concern. Since the identities of both parties to the transaction are identified electronically, and electronic information itself is reproducible and tamperable, making it possible to counterfeit identities. It is particularly important to determine the authenticity and reliability of the counterp...

However, the security and reliability of e-commerce has always been a concern. Since the identities of both parties to the transaction are identified electronically, and electronic information itself is reproducible and tamperable, making it possible to counterfeit identities. It is particularly important to determine the authenticity and reliability of the identity of the counterparty

Since the CRL list is issued at a certain period, it cannot reflect the status of the certificate to be verified in this period in real time. Although the online certificate status query solves this defect, it is highly dependent on the transmission speed of the network and the design of the database. Improve the efficiency of online certificate status query, which is the deficiency of the existing technology
