Broad term used to describe the measures and controls taken to deny unauthorized persons information derived from telecommunications and ensure the authenticity of such telecommunications.
CRYPTO – Marking or designator identifying all COMSEC key material used to secure or authenticate classified telecommunications
CRYPTO – Marking or designator identifying all COMSEC key material used to secure or authenticate classified telecommunications
Key Material – Sequence of random binary digits used to set up, and periodically change, operations performed by crypto equipment to encrypt, decrypt, and authenticate electronic telecommunications
(When written in all capital letters, CRYPTO has the meaning defined above. When written in lower case letters it’s an abbreviation for cryptographic)
Handled in 2 separate channels:
Handled in 2 separate channels:
1. COMSEC channel – is used to distribute items that are accountable by the COMSEC Custodian to the National Security Agency (NSA)
2. Administrative channels – are used to distribute other COMSEC information and material not accountable by the COMSEC Custodian but rather through the site’s Document Control system
When in doubt, contact the COMSEC Custodian
For purposes of this briefing, we’re concerned with the 1st channel: items that are accountable by the COMSEC Custodian to the NSA

The following minimum conditions must be met prior to granting access to CRYPTO:
The following minimum conditions must be met prior to granting access to CRYPTO:
Final Secret clearance or interim Top Secret
Need-to-Know determination
Receive Cryptographic Access Briefing from COMSEC Custodian, Alternate, or their written designated representative and input into EPSS
As a condition of access you must acknowledge:
As a condition of access you must acknowledge:
- that you may be subject to a non-lifestyle, counterintelligence scope polygraph exam only encompassing questions concerning espionage, sabotage, or unauthorized disclosure of classified information
-this examination will be administered in accordance with DoD Directive 5210.48 and applicable laws
CRYPTO Storage
CRYPTO Storage
All CRYPTO must be stored in a GSA approved safe that is either;
1. inside a Closed Area and
2. Under IDS control or covered by guard patrols every 4 hours
Do not use lockbar containers for storing CRYPTO
Keyed CCI & Classified Hardware Storage Requirements:
If being used, must be located in a Closed Area
If not being used, must be stored in a GSA safe
Storage of unkeyed CCI
May be stored like a high value item (e.g. within locked cabinet or storage room) but regularly sighted.
For STE, see COMSEC Custodian for briefing
Do NOT:
Do NOT:
store COMSEC safe combinations electronically (not even on a classified computing system)
place CRYPTO on any computer system (not even if the system is approved for it) until you’ve received written permission from the COMSEC Custodian
move any COMSEC equipment or CRYPTO (not even temporarily) to another location without the COMSEC Custodian’s prior written permission
Hand Receipt Items
Hand Receipt Items
Items Hand Receipted to you by the COMSEC Custodian become your personal responsibility and may never be transferred by you to another person or organization
To initiate transfer for any of your items, you must contact the COMSEC Custodian
Another properly cleared and briefed person may use your items but this does not relieve you of its responsibility
Key Disposition Record
Key Disposition Record
Completed by users as they load key material to ensure a continuous chain of accountability (Records are classified at least CONFIDENTIAL for CONFIDENTAL key and above. Unclassified key disposition Records are marked Unclassified/FOUO)
The following are the only disposition records you might have to use:
