CEF eDelivery Factsheet Now Available

European Commission, 2017

The European Commission is happy to announce the publication of the Connecting Europe Facility (CEF) eDelivery building block factsheet.

The  factsheet is an easy read for absolute beginners on AS4 and the eDelivery building block. It provides the basic information on eDelivery's key concepts, use cases, benefits and how to get started

The CEF eDelivery Building Block helps users to exchange electronic data and documents with one another in a reliable and trusted way.

CEF eDelivery is based on a distributed model called the “4-corner model”. In this model, the back-end systems of the users don’t exchange data directly with each other but do this through Access Points. These Access Points are conformant to the same technical specifications and therefore capable of communicating with each other. As a result of this, users adopting CEF eDelivery can easily and safely exchange data even if their IT systems were developed independently from each other.

The eDelivery Building Block of the Connecting Europe Facility proposes the use of the AS4 messaging protocol to create a secure channel for the transmission of documents and data by electronic means, over the internet or via a private network. AS4 both provides evidence relating to the handling of the transmitted data as well as protecting it against the risk of loss, theſt, damage or any unauthorised alterations

To help realise the Digital Single Market, the Connecting Europe Facility (CEF) programme funds a set of generic and reusable Digital Service Infrastructures (DSI), also known as building blocks. The CEF building blocks offer basic capabilities that can be reused in any European project to facilitate the delivery of digital public services across borders and sectors. Currently, there are five building blocks: eDelivery, eInvoicing, eID, eSignature and eTranslation. Visit CEF Digital 2018 to find out more: ec.europa.eu/cefdigital
