The differences between Affiliate Registration Organisations and Affiliate Registration Authorities are primarily their position within the WISeKey PKI and the infrastructure required to operate them. Affiliate Registration Organisations provide the Registration functions for End Users as they identify certificate applicants, process certificate issuance, suspension, and revocation requests as well as maintain an archive of their provision of such certification services. Because of the basic infrastructure they are required to maintain, they have less autonomy than Affiliate Registration Authorities for localising and tailoring their certification services to specific needs.
