Define “EKMS”
Electronic Key Management System (EKMS) - The logistics and accounting system
through which electronic key is accounted, distributed, generated, controlled, destroyed
and safeguarded. It also provides management of physical key and non-key COMSEC
related items.
Define “COMSEC”
Protective measures taken to deny unauthorized persons information derived from
telecommunications of the U.S. Government concerning National security; protective
measures taken to ensure the authenticity of such telecommunications.
Discuss the responsibilities of a Local Element (LE).
LE personnel are responsible to their Commanding Officer for the proper management
and security of all COMSEC material held by the command. LEs are responsible to the
parent or servicing account (or to the LE (Issuing)) for the proper accountability, security,
control, and disposition of COMSEC material issued to them.
Define “TPI”
Two Person Integrity (TPI) is a system of handling and storing, designed to prevent
single-person access to certain COMSEC material.
Describe TPI Handling.
TPI handling requires that at least two persons, authorized access to COMSEC keying
material, be in constant view of each other and the COMSEC material requiring TPI
whenever that material is accessed and handled.
Describe TPI Storage
TPI storage requires the use of two approved combination locks (each with a different
combination) with no one person authorized access to both combinations.
Define “CCI”
Controlled Cryptographic Item (CCI) A secure telecommunications or information
handling equipment, or associated cryptographic component, which is unclassified but
controlled.
Define “Physical Security”
Physical measures designed to safeguard COMSEC material or information from being
accessed or intercepted by unauthorized persons.
What are Practices Dangerous to Security (PDS)?
PDSs, while not reportable to the national level (NSA), are practices, which have the
potential to jeopardize the security of COMSEC material, if allowed to perpetuate.
Define “EAP” and “EDP” as it applies to communications
Emergency Action Plan (EAP); Emergency Destruction Plan (EDP)
What is an EAP?
A written emergency plan for safeguarding COMSEC or CCI in the event of an
emergency.
What is an EDP?
A written emergency plan for destroying COMSEC or CCI in the event of an emergency.
When must a command have an EAP or EDP?
Every command that holds classified COMSEC or CCI material must prepare and
maintain a current, written emergency plan for safeguarding such material in the event of
an emergency.
For commands located within the continental United States (CONUS), planning must
consider natural disasters (e.g. fire, flood, tornado, and earthquake) and hostile actions
(terrorist attack, rioting, or civil uprising).
For commands located outside of CONUS and deployable commands, planning must
consider both natural disasters and hostile actions and must also include Emergency
Destruction Procedures (EDPs).
Define “DTD” as it applies to communications.
Data Transfer Device
What is the purpose of a DTD?
The DTD is an integral component of the EKMS. The DTD provides cryptographic
security for the storage and transfer of all types of key and protective storage for
related data.
What is the primary DTD used by the Navy?
AN / CYZ-10.
Define “CIK” as it applies to communications.
Crypto Ignition Key
What is the purpose of the CIK?
The information contained in a key storage device (KSD) that is used to electrically lock
and unlock the secure mode of crypto equipment. When the KSD containing a CIK is
inserted in the DTD and the DTD is powered on, the cryptographic capabilities of the
DTD are unlocked to allow for the input/output and handling of key and other information.
What are the three categories of COMSEC incidents?
- Cryptographic
- Personnel
- Physical
Define “Supersession” as it applies to communications.
Supersession refers to a time when a particular item of COMSEC material is no longer
eligible for use.
Describe the three types of supersessions.
- Regular: Supersession based on a specific, pre-determined supersession date for
each edition of material - Irregular: Supersession that is not pre-determined but which occurs as a result of
use. Editions and individual segments af irregularly superseded
COMSEC material are to be destroyed after the material has been used
operationally, when the CONAUTH directs supersession, or, in the case
of maintenance key, it may be used until the key becomes unserviceable. - Emergency: An unplanned change of supersession, usually as the result of a
compromise.
Define “CEOI” as it applies to communications.
Communications-Electronics Operating Instructions
What is included in the CEOI?
The CEOI contains the technical guidance required to establish and maintain
communications support of operations.
1. Call sign assignments
2. Frequency assignments
3. Radio guard charts
4. Radio net identifiers
5. Telephone directory names and numbers
6. Identification and marking panel codes
7. Signal panel message instructions
8. Pyrotechnic and smoke codes
9. Ground-to-air signals
10. Sound warning signals
Define “EEFI” as applied to communications.
Essential Elements of Friendly Information - EEFIs are specific facts about friendly
intentions, capabilities, and activities needed by adversaries to plan and execute effective
operations against our forces.
