Approval Profiles

Approval 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 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 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.

The Profiles and other documents have been copyrighted by tScheme. They, and any subsequently produced documents, remain the intellectual property of tScheme Limited, and should not be distributed or reproduced in any way without prior consent from tScheme Limited. Ordering a copy of a Profile in no way constitutes tScheme approval or membership. If you wish to submit a service for tScheme approval please contact tScheme directly. The Profiles are free for non-commercial use. By this we are not restricting access to businesses, but rather the Profiles must not be used in a way that directly generates revenue and does not lead to claims of compliance without undergoing an assessment by a tScheme-recognised assessor.
