AI Technical Summary
Existing digital certificate authentication systems suffer from problems such as difficulty in cross-domain authentication, slow authentication speed, high maintenance costs, and slow speed in querying certificate revocation lists in cloud and big data application scenarios.
A cross-domain digital certificate authentication method based on consortium blockchain is adopted, which uses multiple certificate authorities as ledger nodes. Distributed hash tables and Bloom filters are used to achieve distributed storage and fast query of certificate data, generate distributed hash tables and improved certificate revocation lists, and improve certificate authentication efficiency and revocation query speed.
It enables fast, secure, and reliable authentication of cross-domain certificate data, reduces overall system overhead, improves the efficiency of certificate retrieval and revocation queries, breaks down information barriers, and supports efficient cross-domain authentication.
