EDI 815 Cryptographic Service Message

Functional Group CS

X12C Communications and Controls Subcommittee

This standard provides the format and establishes the data contents of the Cryptographic Service Message Transaction set within the context of an Electronic Data Interchange (EDI) environment. The purpose of this standard is to provide the data format required for cryptographic key management including automated distribution and exchange of keys. The mechanism is based on existing ANSI X3 and X9 developed by the Accredited Standards Committee (ASCs) X9 and X12 standards and uses X12 structures and data formats. The standard provides an X12 format for key distribution and exchange. The Cryptographic Service Message (CSM) transaction conveys the pertinent keying material for use in the EDI environment. The business requirements addressed in this standard for the key management data encompass distribution and exchange of keying material in support of authentication and encryption.
