993Secured Receipt or Acknowledgment

This X12 Transaction Set contains the format and establishes the data contents of the Secured Receipt or Acknowledgment Transaction Set (993) for use within the context of an Electronic Data Interchange (EDI) environment. The transaction set provides three distinct security services: the 993 provides security protocol error reporting, non-repudiation of receipt for X12.58 authenticated transaction sets or functional groups, and transmission of authentication independent of the document for which the authentication is rendered. When the 993 is used to pass a dis-embodied signature (non-repudiation of origin), both the transaction set and the 993 with the assurance for the transaction set may be transmitted completely independent of each other. A 993 may be generated as a 'trusted receipt' for a 993 that contained a dis-embodied signature.
