scope:

This standard specifies interoperability and security related requirements for the use of encryption with CCITT (i.e., International Telegraph and Telephone Consultative Committee) Group 3-type facsimile equipment. The algorithm used for encryption is the Data Encryption Standard (DES), described in Federal Information Processing Standards Publication 46. Requirements contained in section 3 below relate to the interoperation of DES Cryptographic Equipment, or their operation with associated CCITT Group 3 facsimile equipment. Additional security requirements, not directly relating to interoperability, are contained in Federal Standard 1027.

To facilitate the interoperation of Government facsimile equipment that requires Cryptographic protection using the Data Encryption Standard (DES) algorithm

To prevent the disclosure of facsimile documents

This standard applies to all DES cryptographic components, equipment, systems, and services procured or leased by Federal departments and agencies for the encryption, using the Data Encryption Standard (DES) algorithm, of documents transmitted by CCITT Group 3-type facsimile equipment. Guidance to facilitate the application of this standard, with respect to degradation of security by improper implementation or use, will be provided for in a revision to Federal Information Resources Management Regulation 201-7.

Until Federal Standard 1037 is revised to include encryption terms, definitions of encryption-related terms may be found in the National Communications Security Glossary.
