EDI 815 Cryptographic Service Message

Functional Group CS

X12C Communications and Controls Subcommittee

This Draft Standard for Trial Use contains the format and establishes the data contents of the Cryptographic Service Message Transaction Set (815) for use within the context of an Electronic Data Interchange (EDI) environment. The transaction set can be used 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.

  2. To indicate the beginning of a Cryptographic Service Message (CSM) Transaction Set and to provide both the class or type of the CSM and the cryptographic end parties to the transaction

  3. To provide a mechanism for carrying a field tag and its associated contents from an ANSI X9.17 cryptographic service message (CSM) in an X12 format

  4. To indicate the end of the transaction set and provide the count of the transmitted segments (including the beginning (ST) and ending (SE) segments)
