The RDIG-CA:
- accepts all requests validated by the registration authorities,
- creates and delivers certificates to registration authorities,
- publishes the issued certificates to publicly-accessible on-line stores,
- accepts all revocations from the registration authorities,
- issues and publishes a CRL,
- revoke any issued certificate if RDIG-CA possesses the proofs of
certificate compromise or certificate usage that violates the RDIG-CA CP/CPS.
The RDIG-CA Registration Authorities:
- authenticates the person requesting a person certificate,
- (for user certificate)
determines if the person has the right to have a RDIG-CA certificate,
- sends validated person certificate requests to the RDIG-CA,
- (for a host or host application certificate)
determines if the host has the right to have a RDIG-CA certificate,
- sends validated host and host application certificate requests to
the RDIG-CA,
- delivers certificates to the subscribers if it was not done by the
RDIG-CA itself,
- creates and sends revocation requests to the CA,
- communicates with RDIG-CA using signed electronic mail or via
voice conversations with known persons.
It is up to the Registration Authority to decide wheither user or host has the
rights to have a RDIG-CA certificate. In the process of making such a
decision, Registration Authority can contact the superior person of a requester
to verify the requester's participation in the RDIG consortium projects.
Subscribers:
- must be involved in the RDIG consortium projects,
- must provide accurate information in their certificate requests,
- (for a user certificate) must protect their private key with the
strong password, that is at least fifteen characters in length,
- (for a user certificate) must not keep their private key in
unencrypted form and must not keep private key password along with
the key itself,
- must immediately notify the RDIG-CA Registration Authority in the case
of actual or suspected key loss, disclosure or other compromise.
- must be familiar with the RDIG-CA CP/CPS document and follow the rules
of the certificate usage specified in the CP/CPS document.
- should ask for certificate revocation if the certificate is no longer
needed or the certificated entity is no longer takes part in the projects
of the RDIG consortium.
- should ask for certificate revocation if the data provided in the
certificate is no longer valid.
Relying party:
- must be familiar with this CP/CPS before making any decisions on a
thrustworthness of a certificate issued by RDIG-CA,
- must use the certificate only for purposes that are permitted by this
CP/CPS,
- must check the authencity of RDIG-CA root certificate before using it,
- must verify the current CRL before validating a certificate,
- should update local CRL copy at least once per day.
RDIG-CA will upload all issued certificates to the publicly-accessible
on-line repository. RDIG-CA will maintain Certificate Revocation List (CRL).
RDIG-CA may publish information about pending certificate requests.
The certification service is run with a reasonable level of security but is
provided on a best effort basis. RDIG-CA takes no responsibility for problems
arising from its operation or from the use of certificates it provides.
RDIG-CA denies any financial or other kind of responsibility for damages or
inpayments resulting from its operation.
No financial responsibility is accepted.
This document must be treated according to the current law of Russian
Federation. Legal disputes arising from the operation of the
RDIG-CA will be resolved according with the Russian Federation law.
No fees are charged.
RDIG-CA operates a public web site http://ca.grid.kiae.ru/RDIG/ that contains:
- the certificate for CA signing key,
- current Certificate Revocation List (CRL) signed by RDIG-CA,
- all certificates issued by RDIG-CA,
- past and current versions of RDIG-CA CP/CPS document,
- various information about RDIG-CA and certificates, that can be helpful
to users of RDIG-CA.
The user, host and host application certificates are published as soon as they
are generated. The new Certificate Revocation List (CRL) is issued after each
revocation and at least 7 days before expiration of previous CRL.
The CRL has 30 days validity time.
No access controls to these publications are performed.
RDIG-CA can be audited by the accredited EUGridPMA CA managers to confirm
its compliance to the EUGridPMA Minimum Requirements.
RDIG-CA collects subscriber's full name, organization and unit names and
electronic mailing address. Subscriber's organization, unit name and full name
is included in the user certificate. All collected information is not
confidential. RDIG-CA will not publish subscriber's electronic mailing
address in the list of issued certificates on the RDIG-CA web site.
RDIG-CA by no means wants to access user's, host's or host application's
private key.
Private key is generated only by users or host/service administrators
and must not be disclosed to anyone else. RDIG-CA by no means asks users
to pass their private keys along with the certificate requests.
RDIG-CA does not claim any intellectual property rights on issued
certificates and Certificate Revocation Lists.

3.1 Initial Registration
3.1.1 Types of names
RDIG-CA uses the following types of names for different types of certificates:
- distinguished names for a person certificate:
/C=RU/O=RDIG/OU=users/OU=Organisation/CN=Name,
- distinguished name for a host certificate:
/C=RU/O=RDIG/OU=hosts/OU=Organisation/CN=FQDN,
- distinguished name for a host application certificate:
/C=RU/O=RDIG/OU=services/OU=Organisation/CN=service name/FQDN.
CN component of distinguished name for a person certificate must contain the
person's first and last names.
An optional OU attribute can be inserted between OU=Organisation
component and the CN component in the cases, when organisation name
is not enough to clearly identify the administrative domain
for the certificate holder. One example of such a situation is the organisation
with rich administrative infrastructure and the loose administrative coupling
between its units.
All distinguished names are unique. In cases when user's
first name and last name coincide with existing certificate ones,
middle name or initial may be inserted into the CN field of the
distinguished name.
3.1.2 Method to prove possession of private key
Each request must be signed with the private key corresponding to the
public key provided in certificate request.
RDIG-CA will neither generate nor store any private keys for subscribers.
RDIG-CA Registration Authority verifies the organization identity by checking:
- that the organisation is known to participate in RDIG consortium,
- and the organisation is located in Russia or ex-USSR, by checking
organisational contact information.
3.1.4 Authentication of
individual identity
The RDIG-CA Registration Authority verifies the person identity and it's
affiliation with the claimed organisation entity by face-to-face meeting
with the person, who request the certificate.
Routine re-keying is allowed to current subscribers of RDIG-CA and must take
place before expiration of subscriber's current certificate. The re-key request
must be consisted of certificate request with the new key pair and is to be
signed with the private key of subscriber's current certificate. Resigning of
existing public key is not allowed.
RDIG-CA will not recertify a revoked key. User of a revoked certificate must
obtain a new one following the procedure of initial registration, described in
section 3.1.
3.4 Revocation request
Revocation request must be authenticated, unless RDIG-CA can independently
verify that a key compromise has happened. The preferred method for
authentification is electronic mail message, digitally signed with a non-expired
and previously non-revoked certificate issued by RDIG-CA.
If this is not possible, subscriber
must contact the RDIG-CA Registration Authority which verifies user's
identity using procedures simular to those described in section
3.1.2.
Applicants must generate their own key pair themselves; RDIG-CA will
never generate a key pair for an applicant. RDIG-CA will not accept
private key escrow responsibilities and will reject any certificate request
containing the private key.
The minimum key length for all applications is 1024 bits. The maximum validity
time for each certificate is one year and 31 days.
Generated certificate request must be sent by electronic mail to the
corresponding RDIG-CA Registration Authority. Mail message must be sent from
electronic mail address that does exists and can be mailed to.
RDIG-CA will reject all non-legitimate certification requests; in the case
of rejection applicant will be notified by electronic mail, except for obvious
nonsense requests that will be rejected silently.
Upon a receipt of a certificate request, that is qualified to be valid according
to this CP/CPS, RDIG-CA Registration Authority will verify the request
and authenticate applicant as described in section 3.1. After
successful verification and authentication, RDIG-CA Registration Authority
digitally signs new request and transfers it to RDIG-CA, where certificate
will be issued. The applicant will be notified of issuance by electronic mail
or using another means of communication, if requested by a subscriber. If
communication fails permanently, the certificate will be revoked without
further notice.
A certification request is normally handled in the period of one week, however,
during vacation or national holidays periods the response time can increase
to three weeks.
Valid certificate issued by the RDIG-CA must pass the following requirements:
- Certificate must not be expired.
- Distinguished name must be in the RDIG-CA name space, i.e. it must match
one of the name templates described in section 3.1.1.
- Certificate must have a valid RDIG-CA signature which can be validated with
RDIG-CA certificate, that is available on the URL http://ca.grid.kiae.ru/RDIG/cacrt.pem.
- Certificate must not be listed in the Certificate Revocaton List (CRL)
issued by RDIG-CA, that is available on the URL http://ice.grid.kiae.ru/ca/RDIG/cacrl.pem.
- The CRL must have a valid RDIG-CA signature and must not be expired,
- To guarantee the maximum level of security one should check for new CRL just
before validating the certificate.
A certificate will be revoked when
- the information it contains is no longer correct or proved
to be incorrect, or
- the private key is lost or suspected to be compromised, or
- the certification entity is no longer participated in the RDIG
consortium projects, or
- RDIG-CA have the proofs that certificate usage violates
RDIG-CA CP/CPS rules.
The certificate holder or any other entity presenting proof of knowledge of the
private key compromise or subscriber's data variation can request a
certificate revocation.
RDIG-CA will handle any revocation request, authenticated or unauthenticated.
If RDIG-CA can independently verify that a certificate has been compromised
or misused, RDIG-CA will revoke the certificate. In all other cases, the
revocation request will be authenticated as described in section
3.4.
Revocation request must be passed to the RDIG-CA Registration Authority
who signed the certificate request for the certificate to be revoked.
The rules for passing revocation request to the RDIG-CA
Registration Authority are described in section 3.4.
Revocation request can be canceled within 24 hours after it was received at the
RDIG-CA. But in the case of proved compromise the certificate will be revoked
immediately.
For cancellation of the revocation request the certificate holder
must contact the same RA, as for revocation request.
The rules for passing cancellation request to the RDIG-CA
Registration Authority are just the same as in section 3.4.
