Common eIDAS components

Component	Role	Short description of its use
eIDAS connector	Authentication connector	The component Member States implement to connect to the eIDAS network as a relying party. The connector accepts authentication requests from the service providers of the Member State and forwards the requests to the Member States that needs to authenticate the user. After authentication, the eIDAS connector receives the authentication results and sends them to the requesting service provider (relying party).
eIDAS proxy	Authentication proxy	The component Member States implement to allow authentication with their (notified) eID for services provided in other Member States. The eIDAS proxy receives authentication requests from relying Member States and coordinates authentication. The eIDAS proxy then sends the result to the requesting eIDAS connector.

Common OOP TS components

Component	Role	Short description of its use
Information Desk configuration file	Data requestor and data transferor	The diploma issuing authorities can be located at a national level (Slovenia, Spain) or university level (Portugal). The information will be stored in a configuration file in the DE4A connector for MVP.
SMP	Data requestor and data transferor / central	For each evidence request and response, information on the receivers Access Point (URL) and its certificates are needed. It is expected there will a common project SMP for the test phase, while each Member State will host an SMP for the close-to-production phase. Before sending a request or response, the sending party queries the SMP of the receiver to get this info.
DNS & SML	Data requestor and data transferor	As there are multiple SMPs, the sending party needs to know where to find the SMP of the receiver to get the actual metadata. This location can be found in the centrally CEF-hosted DNS, that will be queried by the access point of the sending Member State. DNS entries will be created from the registration of SMPs: the SML, which is also centrally hosted by CEF.
eDelivery AS4 gateway	Data requestor and data transferor	This component – also referred to as eDelivery access point – handles the secure transfer of the data, including encryption and decryption as well as signing/sealing payloads and validating signatures/seals.
DE4A Connector	Data requestor and data transferor	The DE4A connector is the reference software that data requestors and data transferors can use to connect to the DE4A OOP TS. This eases the work by abstracting the communication with the components. The DE4A Connector already includes the Phase4 AS4 gateway for the Member States that do not want to have a separate gateway.
