COMSEC
Objective 5a. Identify relationship of basic facts and state general principles about requirements for Communication Security (COMSEC) materials.
Comsec
COMSEC-The discipline under Information Assurance (IA) that results from measures and controls taken to deny unauthorized persons information derived from telecommunications and to ensure the authenticity of such telecommunications.
COMSEC
COMSEC TERMS
Everyone is responsible for ensuring the security of military communication. Knowing your role is vital to mission success.
COMSEC Terms
An occurrence involving failure to follow established COMSEC instructions, procedures or standards.
COMSEC Deviation
The individual within an office or area responsible for COMSEC material.
COMSEC Responsible Officer (CRO)
The individual responsible for managing the COMSEC resources of a COMSEC account
COMSEC Manager
The part of COMSEC that results from using all physical measures necessary to safeguard COMSEC material from access by unauthorized persons
Physical Security
Physical Security is part of COMSEC
All COMSEC material must be handled in accordance with specific guidelines.
The principle of safeguarding and accounting for all COMSEC material must be strictly adhered to in order to ensure COMSEC material does not fall into the wrong hands.
Safeguarding our information
SF 153
The SF 153 is used for the transfer, inventory, destruction, or hand-receipt for COMSEC material.
Standard Form 153
AFCOMSEC Form 16
is used to inventory the contents of your security container.
AFCOMSEC Form 16
SF 702
The SF 702 is used to annotate the opening and closing of the secure storage container.
Standard Form 702
SF 704
Secret Cover Sheet (Red)
Standard Form 704
Overnight Registered mail ONLY. It would cause serious damage to national security if it ever was intercepted.
SF 705
Confidential Cover Sheet (Blue)
Standard Form 705
Confidential material is subject to the same mailing procedures as Secret material, with the following exception: confidential material may be sent by U.S. Certified mail rather than by U.S. Registered mail. Under all circumstances, the outer envelope should be marked "Do Not Forward. Return to Sender."
AF Form 144
Top Secret Cover Sheet (Orange)
Air Force Form 144
Never Mailed! Would cause exceptionally grave danger to
national security if it was ever intercepted.
Destruction
There are several methods the Air Force authorizes to officially destroy classified material.
Most of the material you will use is in the form of paper products and will be destroyed by burning, pulping, or using a crosscut shredder.
Destruction of COMSEC
What must be done...
COMSEC must be destroyed within 12 hours after the expiration date listed on the classified document.
A minimum of two individuals are required to destroy COMSEC material:
1. Destruction official
2. Witness
NOTE: The SF 153 & AFCOMSEC Form 16 will be updated and signed upon completion of destruction of the material.
Cryptology
Cryptology, as is explained in the provided video, is used in many applications both civilian and military. Of course, the processes and equipment may differ, but the concepts and reasons are the same.
Crypto
Encryption/Decryption
Encryption is: an algorithmic schemes that encode plain text into a non-readable form also known as cipher text.
Decryption is: the authorized use of cryptographic systems to return encrypted information to its original, readable form.
Encryption/Decryption
Encryption Types
There are two main types of encryption: symmetric and asymmetric
Encryption types
Voice Encryption
Voice encryption telephone devices are designed to operate reliably as both ordinary telephones and secure telephones over the public telephone network. i.e. STE
Voice Encryption
Data Encryption
- Data Encryption Standard (DES)
- Triple DES (3DES)
- Advanced Encryption Standard (AES)
Data Encryption
Data Encryption Types
Just like other forms of technology, data encryption has evolved to meet the needs of today's digital environment. To the right are a few of the data encryption types used by the USAF.
Data Encryption
DES
• Based on secret-key cryptography
• publicly known cryptographic algorithm that converts plaintext into cipher text
• 64 bit key length (56 bit key length + 8 bit parity check)
DES
3DES
• Countermeasure for DES shortfalls
• Three-fold compound operation for encryption/decryption
• 192 bit key length (168 bit key length + 24 bit parity check)
Triple Des (3DES)
AES
Advanced Encryption Standard
• Countermeasure for DES shortfalls
• Three-fold compound operation for encryption/decryption • 192 bit key length (168 bit key length + 24 bit parity check)
What makes one algorithm better than another?
•The algorithm’s key length
•More possible keys, the harder it is to break
•Means more secure
The Answer:
where the encryption takes place
- Voice encryption takes place before it leaves the device or source
- Data encryption takes place in a device separate from the source
*Now, what is the difference between voice and data encryption?

Secure Telephone Equipment (STE)
STE
-STE is designed to use Integrated Services Digital Network (ISDN) telephone lines which offer higher speeds of up to 128k bits per second and are digital.
-The STE sets look like ordinary high-end office desk telephones and can place unsecured calls to anywhere on the public switched telephone network (PSTN).
-The STE cryptographic engine is on a removable Fortezza PC Card that is provided separately.
