摘要

The trust provided by a PKI system rests on the fact that the digital certificates being used within the infrastructure are authentic and can be relied upon. As such, the process of validating certificates is central to the management of risks within a PKI and for resolving any disputes which may arise later. A major problem is that certificate validation is such a complex process, involving numerous convoluted steps, that implementing it properly has been difficult for application providers. This has hampered support for PKI within end-user application so much so that the full potential of PKI technology is not being realised. This paper shows that by transferring the task of certificate validation from end-user applications to dedicated trust servers, we can simplify the implementation and management of a PKI system. Moreover by adopting a delegate certificate validation approach, the ultimate vision of interoperability between disparate PKI "islands" can also be achieved easily. This has the potential of finally shifting PKI technology beyond closed user-groups to an open, inter-PKI communication environment.
