Abstract: The design of certification authority establishment is completed successfully, and the functions of digital certificate are extended by means of building and encoding the authorized extensions items using ASN.1. Furthermore, the RBAC authorization information are appended to user’s certificate to control the owner’s access to objections. Some advantages of this mode are pointed out. The digital certificate avoids the insecure factor in traditional methods.
