Policy Qualifier

Policy-dependent information that accompanies a certificate policy identifier in an X.509 certificate.

Registration Authority (RA)

An entity that is responsible for identification and authentication of certificate subjects, but that does not sign or issue certificates (i.e. an RA is delegated certain tasks on behalf of a CA).

Relying party

A recipient of a certificate who acts in reliance on that certificate and/or digital signatures verified using that certificate. In this document, the terms "certificate user" and "relying party" are used interchangeably.


A storage area, usually online, which contains published materials, such as lists of issued certificates, CRLs, policy documents, etc.

Set of Provisions

A collection of practice and/or policy statements, spanning a range of standard topics, for use in expressing a certificate policy definition or CPS employing the approach described in this framework.

Slovenian Grid Network (SiGNET)

Slovenian Grid Network is the root organisation providing grid and computational network services to Slovenian scientific, educational and research communities.

1.3 Community and Applicability

1.3.1 Certification authorities

SiGNET certificates are signed by SiGNET CA. SiGNET CA does not issue certificates to subordinate certification authorities.

SiGNET CA certificate is signed by itself.

1.3.2 Registration authorities

SiGNET CA manages the functions of its Registration Authority.

Additional registration authorities may be created by SiGNET CA as required. Such trusted intermediaries are formally assigned by SiGNET CA and their identities and contact details are published in an on-line accessible repository at the following URL: http://signet-ca.ijs.si/signet-ralist.txt.

RAs must sign an agreement with SiGNET CA, stating their adherence to the procedures described in this document. RAs are not allowed to issue certificates under this CP/CPS.

1.3.3 End entities

SiGNET CA will issue certificates to entities formally based or having offices in Slovenia, or participating in projects based in Slovenia, and are intended for cross-organisational sharing of resources in the fields of research and/or education.

Certificates can be issued to persons and computer entities (services or hosts). Organisations employing the person or owning the computer entity are not the end entities themselves.

1.3.4 Applicability

Certificates issued are of the following types:

(a) personal certificates:

authorised for document-signing, personal authentication, non-repudiation and encryption of communications

(b) host certificates:

authorised for object-signing, host authentication, non-repudiation and encryption of communications

(c) service certificates:

authorised for object-signing, service authentication, non-repudiation and encryption of communications

The certificates issued by SiGNET CA may not be used for financial transactions or for any commercial usage, including gifts.

3.1 Initial Registration

3.1.1 Types of names

The Subject Name is an X.500 distinguished name. Name forms are further defined in section 7.1.5.

Any name under this CP/CPS starts with C=SI, O=SiGNET. If the subject is part of an organisation, an O=organisation. An optional OU=organisational_unit must be appended if the organisation consists of multiple administrative divisions. (Changes in division name that do not change the organisational layout of an organisation do not constitute a reason to invalidate the current unit name.) The last part is the CN, which takes one of the following forms:

For a Person:

CN is the full name of the subject.The name must include at least one given name in full and the full surname. Only ASCII alphanumeric letters, space and dash may be used.

Example of a full subject name for a person from IJS:

 C=SI, O=SiGNET, O=IJS, OU=F9 CN=Janez Kranjski

A change in the name of the person does not invalidate the certificate and does not necessitate immediate change of the distinguished name.

For a Host:

CN is the host fully qualified domain name DNS name (FQDN). In case the host entity is not an internetwork entity or no such FQDN is assigned for other reasons, the entity is not eligible for certification under this policy.

FQDN domains may be different from organisation and organisational_unit fields since assigned FQDN does not always follow the structural layout of an organisation or network.

Example of a full subject name for a server:

 C=SI, O=SiGNET, O=IJS, OU=F9, CN=host.ijs.si
For a Service:

CN is constructed in the same way and under the same conditions as for hosts, but with a service identifier related to the service appended to the front.

Example of a full subject name for a service:

 C=SI, O=SiGNET, O=IJS, OU=F9, CN=ldap/host.ijs.si

3.1.2 Need for names to be meaningful

The subject name in a certificate must have a reasonable association with the authenticated name of the subscriber.

The common name CN in the certificate subject name must be obtainable from the real subject name. For persons it must be obtainable from a name of the person. For host certificates, the CN must be formed from the registered fully qualified domain name (DNS FQDN). For a service certificate, the CN must be related to the type of service the certificate is identifying.

The Organisation Name in the certificate subject name must be one of the organisations involved in SiGNET activities. Current list of values available for Organisation Names in the in the certificate subject name can be obtained from the URL mentioned in section 1.3.2.

3.1.3 Rules for interpreting various name forms

See section 3.1.1.

3.1.4 Uniqueness of names

The distinguished name for each certificate must be unique. In case of real subject name duplication, additional numbers and/or letters will be appended to the distinguished name to guarantee uniqueness.

Certificates must apply to unique individuals or resources. Users must not share certificates.

3.1.5 Name claim dispute resolution procedure

Name claim disputes are resolved by discretion of the first person named under section 1.4.2.

3.1.6 Recognition, authentication and role of trademarks

No stipulation.

3.1.7 Method to prove possession of private key

No stipulation.

3.1.8 Authentication of organisation identity

No certificates are issued directly to organisations. Certificate requests for entities such as hosts and services must be made by a secure online submission to SiGNET CA Public Server, signed with a valid personal SiGNET certificate. Alternatively, an e-mail message signed with a valid personal personal SiGNET certificate may be used.

SiGNET CA may take steps to ascertain that the user is indeed entitled to represent the organisation or entity which has the rights over the host or service on behalf of which the certificate request has been made.

If the name of an organisation is requested to be part of a subject name, SiGNET CA may take steps to ascertain that the organisation consents to such use.

In the certificate request, the generic e-mail for the host or service must be specified in the Certificate data part and the e-mail of the user requesting the certificate in the User data.

3.1.9 Authentication of individual identity

A user requesting a certificate must either meet in person with the RA and show their IJS access card, acceptable Slovenian photo ID or acceptable foreign photo ID recognised in Slovenia, such as a passport.

If the identification document is valid and the photo image corresponds to the bearer, the RA shall consider that the user is correctly identified.

The RA must forward a photocopy of the document for safekeeping in the CA.

Additionally, the RA may consider that the user is correctly identified if the RA has previously identified the user using the procedure described above and the user can prove possession of his/her secret key of an existing certificate issued by SiGNET CA. In this case the RA must check by telephone or personal conversation that the request originated at the known user.

If authentication is not completed within fifteen days of receipt of the certificate request by the RA, the request will be deemed to have expired. The process of submitting a certificate request and complying with the authentication procedure as per sections 3.1.8 and 3.1.9 shall have to be repeated.

3.2 Routine Rekey

Rekeying of certificates will follow the same procedure as an initial registration.

Additionally, rekeying of certificates of persons before their expiration can be requested by submitting a rekey request to the SiGNET CA Public Server, signed by the subscriber's current personal SiGNET CA certificate.

3.3 Rekey After Revocation

A public key whose certificate has been revoked shall not be re-certified.

Rekey of certificates after revocation follows the same rules as an initial registration.

3.4 Revocation Request

Unless SiGNET CA can independently verify that a key compromise has occurred, a revocation request must be authenticated before being accepted. Anyone can make certificate revocation requests by sending email to the CA. However, the CA will not revoke a certificate unless the request is authenticated, or it can be verified independently that there is reason to revoke the certificate. See section 4.4.

Authenticated certificate revocation requests may be made by


4.1 Certificate Application

Any certificate application request to SiGNET must follow the following provisions:

Maximal lifetime of a certificate is one year. The default validity period is one year.

Certificate requests are made via SiGNET CA's public web interface at http://signet-ca.ijs.si/. Alternatively, if the web interface can not be used, certificate requests can be made via e-mail with the attached public key in PEM-format at signet-ca.user@ijs.si.

Certificate requests are submitted also through any additional approved RA's as per section 1.3.2.

4.2 Certificate Issuance

The first step in the issuance process is the approval of the request by an RA (including SiGNET CA's own RA). The following requirements must be fulfilled:

If all the above requirements are fulfilled, then RA approves the request and passes on the request to the CA for issuance of a certificate.

The subject will be notified by e-mail. If the subject is a person, the e-mail will be sent to the address accompanying the request. Otherwise the e-mail will be sent to the address specified in the request. In the case of rejection, the e-mail will state the reason.

If the e-mail fails to be delivered in a period of 5 days, the certificate is revoked without further notice.

Once a certificate request has been approved by the RA, the certificate is normally issued by the CA within seven working days.

4.3 Certificate Acceptance

No stipulation.

4.4 Certificate Suspension and Revocation

4.4.1 Circumstances for revocation

A certificate will be revoked when the information it contains is suspected to be incorrect or compromised. This includes situations where:

  1. The subscriber's private key is lost, destroyed or suspected to be compromised;

  2. The information in the subscriber's certificate is suspected or confirmed to be inaccurate;

  3. The subscriber no longer needs the certificate to access Relying Parties' resources;

  4. The subscriber no longer fulfills the conditions for participation in SiGNET;

  5. The subscriber violated his/her obligations;

  6. The system or service to which the certificate has been issued has been retired.

In addition, the CA will revoke all certificates in the event that its key has been compromised (as per section 4.8.3) or in the event that the CA has been terminated (as per section 4.9).

4.4.2 Who can request revocation

A certificate revocation can be requested by the holder of the certificate to be revoked or by any other entity presenting proof of knowledge of circumstances for revocation, as described in section 4.4.1.

4.4.3 Procedure for revocation request

The entity requesting the revocation must send the revocation request with an authenticated deposition via the public web interface at SiGNET or by a signed e-mail to SiGNET CA or a SiGNET RA. If this is not possible the CA/RA must be contacted directly. Authentication can be performed as per section 3.1.9.

In both cases above, the requesting entity must specify the reason for the revocation request and provide evidence of circumstances as described in section 4.4.1.

4.4.4 Revocation request grace period

There will be no grace period associated with certificate revocation. SiGNET CA handles revocation requests with priority and a certificate will be revoked as soon as possible after circumstances for revocation, as described in section 4.4.1, are established.

4.4.5 Circumstances for suspension

There is no provision for certificate suspension.

4.4.6 Who can request suspension

No stipulation.

4.4.7 Procedure for suspension request

No stipulation.

4.4.8 Limits on suspension period
