What is AS4? Intro A standard for reliable en secure message exchange using web services Payload agnostic (not being tied to any defined SOAP action or operation) Implementation guideline within ebMS 3.0 Starting points are: ebMS 3.0 as a bases requirements from AS2 just-enough design principle

What is AS4? Technical highlights November 22, 2018 What is AS4? Technical highlights Support for SOAP 1.1 and 1.2 enveloping structure Payload agnosticism Support for single or multiple payloads contained either within the SOAP body or as SOAP attachment(s) Support for payload compression (GZIP [RFC1925]) Support for message-level security including various combinations of XML Digital Signature and/or XML Encryption Support for X.509 security tokens and username/password tokens Support for business receipt of non-repudiation similar to the Message Disposition Notification (MDN) specified by [1] used by AS2 and specified as an XML schema by the ebXML BPSS group Support for the ebMS 3.0 One-Way/Push message exchange pattern with support for either synchronous or asynchronous responses Support for the ebMS 3.0 One-Way/Pull message exchange pattern which is beneficial for exchanging documents with non-addressable endpoints SOAP is de XML envelop die wordt gebruikt bij webservices. De webservice definities zijn berichttype onafhankelijk, dus geen berichttype specifieke services en operaties Toevoegen van bijlages aan een bericht, bijvoorbeeld PDF bij een XML factuur Compressie van de inhoud en bijlagen Extra beveiliging door het ondertekenen en/of onleesbaar maken van het bericht Authenticeren op basis van username / password tokens of X.509 (is sleutel) certificaten Bevestiging van ontvangst van het bericht en controle of het bericht ongewijzigd is ontvangen Het versturen van berichten met directe of indirecte ontvangstbevestiging Het ontvangen van berichten, middels het opvragen en dus niet actief ontvangen (geen webserver, vast IP adres, etc. nodig)

What is AS4? Differences with AS2 November 22, 2018 What is AS4? Differences with AS2 Compatibility with Web services standards. Message pulling capability.

November 22, 2018 What is AS4? Two profiles The two AS4 conformance profiles (CP) are defined below: The AS4 ebHandler CP. This conformance profile supports both Sending and Receiving roles, and for each role both message pushing and message pulling. The AS4 light Client CP. This conformance profile supports both Sending and Receiving roles, but only message pushing for Sending and message pulling for Receiving. In other words, it does not support incoming HTTP requests, and may have no IP address. Twee profilen: Server variant met vast IP adres, altijd online, etc. (leverancier) Klant variant die niet altijd online hoeft te zijn, geen vast IP adres, etc.
