AS2
AS2 (Applicability Statement 2) is a specification developed as part of EDI communication or other business-to-business data over the Internet using HTTP. AS2 provides security for the transport payload through digital signatures and data encryption and ensures reliable delivery and non-repudiation through the use of message disposition acknowledgements (MDN's). AS2 client software interoperability certification testing is performed by the Drummond Group. Both EDI and Non-EDI files (binary files such as PDF) can be routed via this connectivity method.
