FEDERAL STANDARD
TELECOMMUNICATIONS: INTEROPERABILITY AND SECURITY REQUIREMENTS FOR USE
OF THE DATA ENCRYPTION STANDARD WITH CCITT GROUP 3 FACSIMILE EQUIPMENT
This standard is issued by the General Services Administration pursuant to the
Federal Property and Administrative Services Act of
1949, as amended.
1.Scope
1.1.
Description. 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.
1.2
Objectives
1.2.1 Interoperability. To facilitate the interoperation of Government facsimile
equipment that requires cryptographic protection using
the Data Encryption Standard (DES) algorithm.
1.2.2 Security. To prevent the disclosure of facsimile documents.
1.3Application. 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.
1.4
Definitions. Until Federal Standard 1037 is revised to ind ude encryption
terms, def initions of encryption-related terms may be found
in the National Communications Security (Glossary.
