OVERVIEW<br />

CHAPTER 2<br />

CERTIFICATE POLICY MAPPING CRITERIA<br />

201. Certificate Policies (CP) under which Certification Authorities (CA) are<br />

established and operate can vary as well the requirements for creating and managing<br />

certificates. Differences, if not known and managed, can introduce risks to entities<br />

exercising a CCA. Determining comparability and equivalence between CCEB National<br />

Defence certificate policies, is critical prior to moving forward with the crosscertification<br />

of PKIs.<br />

BASELINE REQUIREMENTS<br />

202. The CCEB Nations have agreed to a minimum set of standards that all NDPKIs<br />

must meet. This minimum set of standards is known as the CP Mapping Criteria (CPMC)<br />

and can be found in Annex A of this document. All PKI certificates issued by<br />

interoperable CCEB NDPKIs will be based on the Internet Engineering Task Force<br />

(IETF) Request for comments (RFC) 5280.<br />

SELF-ASSERTION<br />

203. Each CCEB nation will compare their CPs against the mapping criteria found in<br />

Annex A and confirm their compliance or equivalence to the requirements and any stated<br />

guidance listed therein. This process is called self-assertion.<br />

RECORDING AND DISTRIBUTING RESULTS OF THE SELF-ASSERTION<br />

204. The NDPKI Policy Management Authority (PMA) will notify the PMA’s of each<br />

CCEB NDPKI when they have completed their self-assertion and will make available the<br />

formal self-assertion to the NDPKI PMA that they plan to/or are cross-certified with.<br />

Additionally where a criterion in relation to the CPMC cannot be met entirely the NDPKI<br />

PMAs involved shall reach an agreement on the resolution of non-conformance. Such<br />

agreement will be documented and be made available to the other Participant of the bilateral<br />

cross-certification.<br />

Uncontrolled copy when printed<br />

FREQUENCY OF SELF-ASSERTION<br />

205. A CCEB nation is required to complete a self-assertion prior to entering into any<br />

CCA with another CCEB nation or issuing a cross-certificate from their NDPKI to<br />

another CCEB NDPKI. After the initial self-assertion, each NDPKI PMA in a bi-lateral<br />

arrangement shall revalidate the self-assertion on an annual basis and shall share the<br />

results with the other NDPKI PMA in the bilateral arrangement. Additionally, NDPKI<br />

PMAs shall reassert compliance against the CPMC when an applicable NDPKI CP is<br />

amended and shall notify the other NDPKI PMA if any areas of non-compliance have<br />
