A rapid review method to apply digital certificate based on CA-trust set

Abstract

In the information society where digital certificates are widely used, users probably own more than one certificate. Generally, users are required to apply certificates on-site so that RA can verify the authenticity of the information submitted by users. Online application can improve the efficiency of RA, but it is still necessary for RA staffs to manually check the information submitted online. In order to realize automated verification and improve the efficiency of RA further, a CA-trust set is designed for RA, of which every element is CA and is approved by the current RA. Users add a signature to the information submitted to RA with a digital certificate issued by some CA belonging to a CA-trust set, so that RA can complete the verification of information through checking the signature. © 2012 Springer-Verlag.
