The SDD provides protection for facsimiles, e-mail, and computer communications. The "keying stream" is a polymorphic regenerating mathematic algorithm which takes a initialization key and mathematically morphs it into a bit stream pattern.
A portion of the "keying stream" are then mixed back into to the original key, and process repeated. The results is a pseudo-random bit stream that if properly implemented is extremely difficult but not impossible to decrypt.
Even the most sophisticated cryptographic algorithm can be easily expressed in the form of a simple equation in boolean algebra, with the "initialization keys" being used to define the initial key generator settings, and to provide morphing back to the equation. While STU-III audio quality could be better, conversations can take place at a distance over an insecure phone system that would otherwise require a face to face meeting.
While the quality can be improved by using a purely digital STE, the communications infrastructure is rarely able to support their widespread usage.

The unit can be controlled directly or remotely from a PC or computer terminal. Unauthorized calls are terminated without compromising information. Normally factory stock and available for immediate shipment. With a push of a button, the phone call is protected by Bell Labs high grade cryptographic algorithm and public key encryption. The CSD generates and distributes keys using negotiated public key encryption. With public key technology, manual key loading and maintenance is not necessary, thus enabling immediate communications protection.
Every time the secure button is pushed, the CSD generates a new key. This key is unique to the session and to the two communicating CSD s. To further secure the call, random variables derived from the unique key are displayed. By comparing the variables, the sender and receiver can detect if the public key negotiation is being tampered with or spoofed. Connection to the Handset of a Typical Telephone By snapping select modules into the rear of the CSD , universal telephone compatibility is achieved.
Users can keep the phone of their choice and operate with analog and digital telephone lines and switches. Voice clarity during the encrypted call provides speaker recognition.

We strongly recommend you to use a trusted Wi-Fi network for all internet connections.
When the device connects to the Internet tap the Next button to continue. Was this article helpful? Yes No. The display is critical because each party uses it to authenticate the distant party. For this reason, the identification information is also referred to as "authentication data. The Command Authority defines the DAO description, which specifies the terminal user's parent department, agency, or organization. The DAO description may be one or two lines:.
This line is displayed on the terminal of the distant party throughout a secure call. It is displayed briefly to the distant user during the secure call setup. The User Representative next enters the second part of the user identification: the Additional Identification Data, or "free form" information.
The STU-III user determines this information, such as a specific location, section, position title , or project, even the user's name, and notifies the User Representative. In all, three lines are available for authentication data. If the Command Authority has already specified a two-line DAO description, then there can be only one line of free form information:. See inside back cover for further information. You'll find some obvious differences, such as price, and others that are more subtle.
Certify your facility's eligibility to the vendor and provide the following:. Tailor the SPP to your specific operation. Remember that although the user will be briefed on the use of the STU-III and the security precautions for the unit, the user's primary source of information will be the SPP. To get you started, the contents might include:. If there is any difficulty, call the EKMS immediately at Take delivery of the additional KSDAs, if any, that you ordered from a vendor.
No special protection requirements apply to these blank devices, which will become CIKs. Once they become CIKs, however, they are locally accountable items. Just follow the directions the vendor provides. Attach the handset cord to the handset and main unit. Then insert the telephone cord into an RJ jack household telephone jack. Finally, supply the power plug the unit into a V wall outlet. That's all there is to it. Specific data port and computer security requirements are provided by DIS.
To test the nonsecure operation of each unit, place a nonsecure call. Once you start the keying sequence you will have from three to ten minutes to complete the sequence and make your first CIK. If this occurs, you will lose your seed key. Remember, there is ample time to complete the keying process.
Do not rush. After checking the nonsecure operation of the unit s to be filled, load operational key s , if any, into the appropriate STU-III s. For each keyset to be established within the STU-III terminal, follow the same procedures provided for loading seed key.
While it is not necessary to call the EKMS rekey number , you are urged to do so. When using the yellow card, ensure that both sides are completed. Local CIK account-ability records must be retained until the terminal s is zeroized. Destruction reports will seldom be required. Protect each keyed STU-III unit that contains key and that has a CIK inserted in it at the highest security level of the information that the operational key can protect. The briefing must cover at least the following:.
Substantial amounts of classified and sensitive unclassified information have leaked to our adversaries over nonsecure telecommunications circuits.
