Approval Profiles

New Profile review

Following the most recent review of the PKI-related Approval Profiles it was decided that a new Profile single was needed to cover a service providing the functionality of a Root Certificate Authority rather than, as currently, require such a service to use the Certification Authority Profile (tSd0102) and the associated 5 or 6 sub-service Profiles.

To participate in a review of the result of that process, please visit the review page.

Current Profiles

tScheme assessments relate to the creation and lifecycle management of credentials that are primarily used online to assert identity or other related attributes. The technology underpinning the credentials is either public key cryptography (PKI) or non-PKI (such as PIN/password, chip & PIN smartcards, etc).

The assessments are based on sets of requirements grouped according to the type of service to be assessed – for example a PKI-based service could relate to Certificate Status Management or a non-PKI-based service could relate to Credential Management. Each set of requirements is grouped in a document referred to as a Profile.

As a result there are two sets of Profiles – PKI and IdP (non-PKI) – each set having an overall service Profile – Certificate Authority Profile or Identity Provider Profile respectively – and this Profile then identifies the related sub-service Profiles as appropriate, which may also be provided by the organisation or by a third-party.

To complete an assessment a service provider, whether PKI or IdP, will also always be assessed against a set of requirements related to the actual organisation providing the service and this is known as the Base Profile.

These Profiles cover the criteria against which Electronic Trust Service Providers are assessed when applying for a tScheme Grant of Approval.

Building and maintaining tScheme profiles

Where the TSP is claiming compliance with the requirements of [eIDAS], then there are specific requirements included in the following PKI Profiles: Certification Authority, Registration Authority, Certificate Generation and Signing Key Pair Management (optional).
