what entity within a pki verifies user requests for digital certificates
Public key infrastructure The PKI role that assures valid and correct registration is called a registration authority (RA). An RA is responsible for accepting requests for digital certificates and authenticating the entity making the request.[2] In a Microsoft PKI, a registration authority is usually called a subordinate CA.[3]
Three certainties There is a requirement that the beneficiaries of a trust, known as the objects, be certain. Within express trusts this is a particularly complex area, because the test used to determine certainty varies between fixed trusts, mere powers and discretionary trusts.[24] Fixed trusts are trusts for a specific, named list of individuals, with Alastair Hudson giving the example of "Â£10,000 to be held upon trust equally for the complete team of 11 Sunderland Football Club players who started the 1992 Cup Final at Wembley". The test for fixed trusts is that the trustees must be able to give a complete list of the beneficiaries, as laid down in IRC v Broadway Cottages.[25] If there are any potential beneficiaries who the trustees are not certain of, or the trustees cannot compile a complete list, the trust is void for uncertainty.[26]
