Description & Purpose
The communication security (COMSEC) equipment description provides a description of a COMSEC equipment, device, or component; it describes in detail the equipment's functional, key and rekey, and transfer device interface design.
The principal uses of this DID are to provide the Government Office of Key Management input for equipment and/or system certification, and for determining equipment/system compatibility.
Application & Interrelationship
This Data Item Description (DID) contains the format and content preparation instructions for the data product generated by the specific and discrete task requirement as delineated in the contract.
This DID is applicable to the development and acquisition of COMSEC equipment.
The requirements contained herein are applicable to all COMSEC equipment development, modification, and product improvement contracts.
Preparation Instructions
10.1General.This COMSEC equipment description will document in detail the COMSEC equipment's design to show that its design meets the Government Office of Key Management's key architecture guidelines.
10.2Content requirements.The COMSEC equipment description shall contain the following information:
10.2.1Introductory Information.Introductory information shall state the purpose of the equipment, device, or component (i.e., encryption/decryption of teletype and data traffic).
10.2.2Functional description.Defines the functional capabilities of the equipment, device, or component.
10.2.3Compatible equipment list.Identifies and lists existing and/or developmental equipment that will have a compatible interface with this equipment, device, or component. Compatible fill/transfer devices shall be included in this list. It shall also state how this (these) interface(s) was (were) verified.
10.2.4Data rate.Defines all interface input and output data rates for this equipment, device, or component.
10.2.5Cryptonet size.Defines the cryptonet size for this equipment, device, or component. States whether this definition is proposed or approved, and if approved, identifies the approving authority.
10.2.6.1Equipment.States the classification of this equipment, device, or component. Defines whether this classification applies to a keyed and/or unkeyed equipment, device, or component.
10.2.6.2Data.Defines the highest classification level of data that can be stored and/or used in this equipment, device, or component.
10.2.7Algorithm.Defines the algorithm(s) used in this equipment, device, or component. Identifies whether this (these) algorithm(s) has (have) been approved for use in this equipment, device, or component, or whether approval is pending. If approved, identifies the approving authority who approved the use of this (these) algorithm(s).
10.2.8Cryptographic key.Defines the type(s), quantity(ies), size(s), bit pattern(s), cryptoperid(s), and storage capacity of cryptographic key proposed/approved for use in this equipment, device, or component. Identifies the approving authority for the application of this (these) key(s).
10.2.9Rekey capability.Defines the method(s) (i.e., SAVILLE Advanced/Remote Keying (SARK), automatic remote rekeying, manual remote rekeying, key update capability) of rekey for this equipment, device, or component.
10.2.10National Security Agency (NSA) Data Standard (DS) 100.Defines how DS-100 applies to and is used within this equipment, device, or component.
10.2.11National Security Agency (NSA) Data Standard (DS) 101.Defines how DS-101 was incorporated within this equipment, device, or component.
10.2.12Interface definition.Diagrams and defines all equipment interfaces. Specifies connectors and connector pins associated with key management functions (i.e., data input and output, rekey).
10.2.13Timing diagram.Diagrams and defines internal equipment processes associated with key management functions (i.e., data processing, key generation, key translation, rekey).
10.2.14Human interface.Separately specifies all operator actions and procedures associated with all key management functions (i.e., data processing, key generation, key translation, rekey). Defines operator actions in a step by step process.
