Grid Security Infrastructure (GSI) is the most common security infrastructure for grid computing, which is also based on Public Key Infrastructure (PKI). Therefore, the process to issue certificates for grid users, which is usually including interviewing with Registration Authorities (RAs) for identifying the user in person, is complicate and difficult to ensure reliability. The authors could, therefore, rely on the certificate issuance process of national PKI, which includes RA system guaranteed by governments. However, it is not possible to adapt the national PKI on GSI without modifying security software due to technical and legal problems. Either certificate validation or certificate path validation will be fail in that case.
