1 INTRODUCTION

1.1 Overview

This is part 3 Additional Requirements of the Programme of Requirements (PoR) of the PKI for the government and is called the Additional Requirements PKIoverheid. Set out in the PoR are the standards for the PKI for the government. This section of part 3 relates to the additional requirements laid down for the services of a Trust Service Provider (TSP) within the PKI for the government. Within the PKI for the government, a distinction is made between various domains. These additional requirements relate to all types of certificate issued under these domains, whereby the distinction is made in the corresponding PoR parts.

A detailed explanation regarding the background and structure of the PKI for the government, as well as the cohesion between the various parts within the PoR is included in part 1 of the PoR.

1.1.1 Design of the Certificate Policies

Part 3 of the Programme of Requirements of PKIoverheid consitis of the following elements:

  • Part 3 Basic Requirements: The basic requirements are applicable to all Certificate Policies in part 3 of the Programme of Requirements;
  • Part 3 Additional Requirements: Contains all additional requirements that are applicable to one or more CPs, but not all CPs;
  • Part 3 Reference matrix PKIoverheid and ETSI: An overview of PKIoverheid requirements with a reference to the applicable ETSI norm(s);
  • Part 3a through 3j: The Certificate Policies for the different PKIoverheid certificates. These CP’s govern the issueance of end entity certificates under the regular root, the private root and the Extended Validation root. These root certificates are broken down into different versions or generations.

The CPs in part 3 of the PoR are structured as follows:

  • Part 3a: Personal certificates in the Organization domain;
  • Part 3b: Services authentication and encryption certificates in the Organization domain;
  • Part 3c: Personal certificates in the Citizen domain;
  • Part 3d: Services certificates in the Autonomous Devices domain;
  • Part 3e: Website and server certificates in the Organization domain;
  • Part 3f: Extended Validation certificates under the Extended Validation root;
  • Part 3g: Services authentication and encryption certificates in the Private Services domain;
  • Part 3h: Server certificates in the Private Services domain;
  • Part 3i: Personal certificates in the Private Services domain;
  • Part 3j: Organization Validation certificates under the Extended Validation root.

All PKIoverheid requirements have a unique and persistant number which also contains a reference to RFC 3647. Furthermore, each PKIoverheid requirement can have a relation with one or more ETSI requirements for the issuance of PKI certificates. In a separate Excel tabsheet in the OoA template “Referentiematrix PKIoverheid and ETSI” this relationship is listed, aiding in interpreting the PKIoverheid requirements in the context of the ETSI requirements.

The PKIoverheid requirements are divided into the Basic Requirements and the Additonal Requirements. The Basic Requirements are applicable to all CPs. Additionally, each CP contains references to the Additional Requirments that are applicable to that specific CP. The CPs do not contain reference to the Basic Requirements or relevant ETSI standard, as these are automatically applicable.

To comply with a specific CP the applicable ETSI standard, the Basic Requirements and part of the Additional Requirements of PKIoverheid must be met.

Incorporated in chapters 2 to 9 inclusive are the specific PKIoverheid requirements. The table below shows the structure within which all PKIoverheid requirements (PKIo requirement) are specified individually.

Requirement Unique number of the PKIo requirement. In each paragraph, consecutive numbering is used for the PKIo requirements. In combination with the RFC 3647 paragraph number, this forms a unique label for the PKIo requirement.
Description Description of the PKIo requirement that applies to this domain of the PKI for the government.
Comment To provide a better understanding of the context in which the requirement has to be placed a comment has been added to a number of PKIo requirements.

1.3 PKI participants

1.3.1 Certification authorities

In this document the distinction is made between the term Certification Authority (CA) and Trust Service Provider. In international usage, "CA" is an umbrella term that refers to all entities authorized to issue, manage, revoke, and renew certificates. This can apply to the actual CA certificate as well as the organization. In this CP, the organization which holds a CA is refered to as a TSP. The term CA is used to refer to the infrastructure and keymaterial from which a TSP issues and signs certificates.

All TSPs issuing PKIo certificates are mentioned in the relevant parts of the PoR 3a through 3j.

1.3.2 Registration authorities

Registration Authorities (RAs) are entities that approve and authenticate requests to obtain, renew, or revoke certificates. RA tasks within PKIoverheid are as follows:

  • Identify and authenticate subscribers
  • Verify that subscribers are authorizated to request or revoke certificates
  • Approving individuals, entities, and/or devices that are to be included in a certificate.

After performing the tasks listed above they will authorize and/or request a TSP to issue, renew, or revoke a certificate.

1.3.3 Subscribers

Subscribers within the PKIoverheid hierarchy are defined as organizations or individuals (working for organizations) to whom a TSP has issued (a) PKIoverheid TRIAL certificate(s). Before issuance of the first certificate the subscriber has to agree to a Subscriber agreement supplied by the TSP. Requirements for this subscriber agreement are listed in relevant sections of this CP.

The terms and conditions for users that are made available to the relying parties have to state that the relying party has to check the validity of the full chain of certificates up to the source (root certificate) that is relied on.

The terms and conditions must also state that the subscriber is personally responsible for prompt replacement in the event of an approaching expiry of validity, and for emergency replacement in the event of a private key compromise and/or other types of emergencies relating to the certificate or the higher level certificates. The subscriber is expected to take adequate measures in order to safeguard the continuity of the use of certificates.
Comment

The validity of a certificate does not indicate the certificate holder's authority to perform a specific transaction on behalf of an organization or pursuant to his or her profession. The PKI for the government does not arrange authorization; a relying party has to convince itself of that in a different manner.

It is advisable to inform the subscriber to take into account the “ICT beveiligingsrichtlijnen voor de transport layer security (TLS)” of the NCSC when using PKIoverheid server certificates. This advice can be obtained online via the website of the NCSC.

6.5.1 Specific computer security technical requirements

6.5.1-pkio114 —

Description

The TSP has to use multi-factor authentication (e.g. smartcard with personal certificates and a personal password or biometry and a personal password) for the system or all user accounts which are used to issue or approve certificates. This is also mandatory for systems or the user accounts with which data validation takes place.

The TSP may waive this measure for systems or user accounts with which data validation takes place, provided that it has implemented technical measures, as a result of which a user account can only validate certificate requests on the basis of a pre-approved list of domains or e-mail addresses.
Comment Multi-factor authentication tokens cannot be connected permanently or semi-permanently to the system (e.g. a permanently activated smartcard). That is because this would enable certificates to be issued or approved (semi) automatically, or for non-authorized staff to issue or approve certificates.

6.5.1-pkio115 —

Description The staff of external Registration Authorities (RA) or Resellers may not have access to the system or the user accounts of the TSP which enables issuance or approval of certificates. This function is restricted to authorized staff of the TSP. If an RA or a Reseller does have this access, the RA or the Reseller will be seen as part of the TSP and it/they have to comply with the PKI for the government Programme of Requirements fully and demonstrably.
Comment -

6.5.1-pkio116 —

Description

The TSP SHALL prevent unauthorized access to the following core services:

  • registration service,

  • certificate generation service,

  • subject device provision service,

  • dissemination service,

  • revocation management service,

  • revocation status service.

To this end, these core services are separated either

  • physically or logically from the non-PKI network domains, or

  • physically or logically from the PKI network domains that do not meet the Network Security Guidelines of the CA/B Forum, or

  • physically or logically from the PKI network domains that do not meet the network related PKIoverheid requirements from RFC3647 paragraph 6, “Technical Security Controls”.

The TSP enforces a unique authentication for each core service mentioned above.

When the physical or logical separation of the network domains described above is not feasible, the various core services must be implemented on separate network domains, where there has to be a unique authentication for each core service mentioned above.

The TSP must document the organization of the network domains, at least in a graphical manner.

This requirement does not apply to other environments, such as acceptance and test.

RFC 5280 KeyIdentifier The value MUST include the SHA-1 hash from the authorityKey (public key of the TSP/CA).
IssuerAltName A No This attribute allows alternative names to be used for the TSP (as issuer of the CRL) (the use is advised against). RFC 5280 The DNS name, IP address and URI could potentially be entered into this field. The use of an rfc822 name (e-mail address) is NOT allowed.
CRLNumber V No This attribute MUST contain an incremental number that provides support when determining the order of CRLs (the TSP provides the numbering in the CRL). RFC 5280 Integer
DeltaCRLIndicator O Yes If 'delta CRLs' are used, a value for this attribute MUST be entered. RFC 5280 BaseCRLNumber Contains the number of the baseCRL of which the Delta CRL is an extension.
issuingDistributionPoint O Yes If this extension is used, this attribute identifies the CRL distribution point. It can also contain additional information (such as a limited set of reason codes why the certificate has been revoked). RFC 5280 If used, this field MUST fulfil the specifications in RFC 5280
FreshestCRL O No This attribute is also known by the name 'Delta CRL Distribution Point'. If used it MUST contain the URI of a Delta CRL distribution point. This is never present in a Delta CRL. RFC 5280 This field is used in complete CRLs and indicates where Delta CRL information can be found that will update the complete CRL.
authorityInfoAccess O No Optional reference to the certificate of the CRL.Issuer. RFC 5280 id-ad-caIssuers (URI) MUST conform to 5.2.7 of RFC 5280.
CRLReason O No theCRLReason MUST indicate the most appropriate reason for revocation of the certificate, as defined in the CPS of the TSP. The field MUST NOT contain the certificateHold value. RFC 5280 reasonCode Explains the reason for revocation.
holdInstructionCode N No Is not used. RFC 5280 OID The PKI for the government does not use the 'On hold' status.
invalidityDate O No This attribute can be used to indicate a date and time on which the certificate has become compromised if it differs from the date and time on which the TSP processed the revocation. RFC 5280 GeneralizedTime
certificateIssuer A Yes If an indirect CRL is used, this attribute MAY be used to identify the original issuer of the certificate. RFC 5280 GeneralNames

10.4 Profile OCSP

10.4.1 General requirements in relation to OCSP

  • If the TSP supports the Online Certificate Status Protocol (OCSP), OCSP responses and OCSPSigning certificates MUST fulfil the requirements relating to this stipulated in IETF RFC 6960.

  • OCSP Signing certificates MUST correspond with the X.509v3 standard for public key certificates. General requirements in relation to certificates are listed in RFC5280

  • The [X.509] standard allows unlimited extension of the attributes within a certificate. In connection with interoperability requirements, this may not be used within the PKI for the government. Only attributes indicated in this appendix as Compulsory (V), Optional (O) or Advised Against (A) may be used.

  • OCSP Signing certificates must fulfil the profile for services certificates set out in part 3b of the Programme of Requirements PKIoverheid, with the following exceptions:

10.4.2 OCSP Signing certificate attributes

Field / Attribute Criteria Critical? Description Standard reference Type Explanation
Issuer V MUST contain a Distinguished Name (DN). PKIo An OCSPSigning certificate MUST be issued under the hierarchy of the PKI for the government.
KeyUsage V Yes

The attribute extension specifies the intended purpose of the key incorporated in the certificate. In the PKI for the government, for each certificate type various bits are incorporated in the keyUsage extension.

In OCSPSigning certificates, the digitalSignature bit MUST be incorporated and the extension marked as being critical. The non-Repudiation bit MUST NOT be included.

 RFC 5280, RFC 2560 BitString
CertificatePolicies V No MUST contain the OID of the PKIoverheid certificate policy (CP) as described alongside, the URI of the CPS, and a user notice. The OID schedule to be used in the PKI for the government is described in the CP - Services. RFC 3739 OID, String, String

The OID for OCSP certificates (for all domains) under the G2 is: 2.16.528.1.1003.1.2.5.4.

The OID for OCSP certificates under the G3 is as follows:

- Organization Person: 2.16.528.1.1003.1.2.5.1

- Organization Services: 2.16.528.1.1003.1.2.5.4

- Organization Servier: 2.16.528.1.1003.1.2.5.6

- Citizen: 2.16.528.1.1003.1.2.3.1

- Autonomous Devices: 2.16.528.1.1003.1.2.6.1

The OID for OCSP certificates under the EV is 2.16.528.1.1003.1.2.7

The OID for OCSP certificates under the Private Root is as follows:

- Private Services/server: 2.16.528.1.1003.1.2.8.4

- Private Persons: 2.16.528.1.1003.1.2.8.1
ExtKeyUsage V Yes MUST be used with the value id-kp-OCSPSigning. RFC 5280
ocspNoCheck V/O

The CA/B Forum Baseline Requirements require the use of the ocspNoCheck for publicly trusted server and EV certificates.

For the other PKIoverheid certificates the use is optional.

 RFC 2560

The CA/B Forum Baseline Requirements require the use of the ocspNoCheck. It is therefore not clear how browsers are to react on OCSP responder certificates without a ocspNoCheck extension.

Browsers will most probably not check the status of an ocsp signing certificate without the extension.
