Iso registration authorities are different from a maintenance agency. Maintenance agencies have the right to update certain elements in an international standard and, for political reasons, the secretariats of WADA`s bodies are part of the ISO system (member bodies or organisations to which a member body delegates certain tasks to its country). Accreditation and their operations are subject to approval by the technical committee. There are registration authorities for many standards bodies, such as ANNA (Association of National Numbering Agencies for ISIN), Object Management Group, W3C, IEEE and others. In general, all registration authorities perform a similar function by encouraging the use of a specific standard by facilitating its use. If so, this can be done by applying the standard or verifying customer compliance with a specific application. On the other hand, maintenance agencies can change an element of a standard based on defined rules. B , for example, creating or modifying a monetary code when a currency is created or revalued (for example. B, TRL in TRY for Turkish lira). The Object Management Group has an additional concept of a certified supplier, which is considered an organization that, on behalf of the registrar, is authorized to perform certain processes and procedures documented as part of the standard for such a role. When the customer acts as a registration authority, it encourages subscribers who receive certificates to comply with the terms of the DigiCert subscription contract found on www.digicert.com/subscriber-Vereinbarung.
Another example is the proper organization of Internet registrars of Internet standards Assigned Numbers Authority.  An ISO registration authority (RAs) does not have the right to update standards, but offers a registration function to facilitate the implementation of an international standard (e.g. B ISBN number for books). Often, facilitating the implementation of ISO requirements by nature is best suited to a unit, a NORME. This creates a de facto monopoly situation and therefore the functions and royalties must be taken care of in order to avoid any abuse of such a situation.  In most cases, there is a formal legal contract between the standards body, such as ISO`s general secretariat, and the selected registration authority. While registration authorities generally do not change for a given standard, the position is not formally guaranteed and is subject to verification and reassignment to another company or organization. In some cases, the concept of a registration authority may not exist at all for a standard. It does not apply to administrative workstations or consoles located within the certification body`s security perimeter or to certification centres used by RAs to support certificate management and subscribers.
PKI MULTICERT (Public Key Infrastructure MULTICERT): a set of services provided by MULTICERT, as a certification body or by the registrar, in accordance with the agreement to issue digital certificates relating to the issuance of DCS, on the basis of technology, applications, policies, practices and standards of MULTICERT and related management, in order to ensure security and trust in electronic communications.
