1. Introduction
1.1 Overview
The SECOM Digital Certification Infrastructure Certification Practice Statement(hereinafter, "this CPS") stipulates the rules for operating the Digital Certification
Infrastructure provided by SECOM Trust Systems Co., Ltd. (hereinafter, "SECOM
Trust Systems).
The Digital Certification Infrastructure hereunder, which is operated by SECOM
Trust Systems, is a platform used for the operation of the certification authority(hereinafter, "Private CA users") of SECOM Trust Systems as well as the CA of theusers of SECOM Trust Systems Private CA Services.
The Digital Certification Infrastructure comprises certification infrastructure
systems, such as repository servers for publishing revocation information, CA
certificates, and other information, as a CA, as well as other servers on which theapplications for transmitting certificate signing requests from an RA (Registration
Authority) to an IA (Issuing Authority) are installed.
An organization or any other entity serving as operator of a CA may achieve a highly
reliable and extremely secure CA by building the CA server on the Digital
Certification Infrastructure.
Any CA operated on the Digital Certification Infrastructure has to provide for thetypes and usages of the certificates to be issued, as well as respective rules of practicespecific to that particular CA, as the certificate policy (hereinafter, "CP"). The CA
operated on the Digital Certification Infrastructure must comply with this CPS andthe CP in conducting the operation.
Any provisions in the CP inconsistent with this CPS shall prevail and any provisions
in a separate agreement or the like with SECOM Trust Systems inconsistent with the
CP shall prevail.
This CPS conforms to the RFC3647 "Internet X.509 Public Key Infrastructure
