Definition
The service message AUTACK (Secure Authentication and Acknowledgement Message) enables the transmission of integrity and authenticity data for referenced data. The message is used to transport the digital signature and the related information needed by the recipient to verify the digital signature.
The secure authentication and acknowledgement message (AUTACK) may be used for both national and international trade. It is based on universal practice related to administration, commerce and transport, and is not dependent on the type of business or industry.
Principles
The applied security procedures shall be agreed to by trading partners and specified in an interchange agreement. The secure authentication and acknowledgement message (AUTACK) applies security services to other EDIFACT structures (messages, packages, groups or interchanges). It can be applied to combinations of EDIFACT structures that need to be secured between two parties.
The security services are provided by cryptographic mechanisms applied to the content of the original EDIFACT structures. The results of these mechanisms form the body of the AUTACK message, supplemented by relevant data such as references to the cryptographic methods used, the reference numbers for the EDIFACT structures and the date and time of the original structures.
The AUTACK message can apply to one or more messages, packages or groups from one or more interchanges.
An AUTACK message used as an authentication message shall be sent by the originator of one or more other EDIFACT structures, or by a party having authority to act on behalf of the originator. Its purpose is to facilitate the security services provided by electronic signatures, i.e., authenticity, integrity, and non-repudiation of origin of its associated EDIFACT structures.
