Research on the solution of PKI interoperability based on validation authority

It is important to implement the PKI (Public Key Infrastructure) interoperability in the process of digital certificate application of e-commerce and e-government services. The solution of PKI interoperability using VA (Validation Authority) is proposed to achieve the digital certificate validation in a dedicated server side. In this solution, the related clients do not have to implement the complicated path construction and validation. Moreover, the verification strategies can be uniformly achieved.
