The Qatar Trusted List establishes the anchor of Trust and includes information about the trust service providers or qualified trust service providers, the trust services or qualified trust services they provide, the full history and their qualified status if applicable. The trusted list is the single authoritative source to verify the license status of trust service providers and qualified trust service providers and to confirm if CRA has granted a (qualified) trust service provider, and one or more of its services, with qualified status if applicable.
CRA electronically signs this “Qatar Trusted List” to guarantee its integrity and authenticity.
