GB/T 28455-2012

This standard specifies an entity authentication framework and access architecture that incorporates a trusted third party, defining protocols and security requirements for verifying identities in network environments. It is primarily applied in information security systems, such as secure network access control, e-government platforms, and enterprise authentication services, where reliable identity verification and access management are critical. The standard ensures interoperability and security in scenarios requiring third-party trust, like public key infrastructure (PKI) deployments or multi-domain authentication systems.
