KY-57 voice encryptor. Note fill port in center. A KYK-13 fill device. A fill device or key loader is a module used to load cryptographic keys into electronic encryption machines. Fill devices are usually hand held and electronic ones are battery operated.

Key management: getting keys securely to thousands of cipher devices in the field, perhaps the most difficult part of implementing an encryption system. One NSA goal is benign fill, a technology for distributing keys in a way that the humans never have access to plaintext key.

Key fillers are commonly used for the distribution of the Transmission Encryption Keys (TEK) and Transmission Security Keys (TSK), such as Frequency Hopping (FH) tables. The latter is also known as Electronic Counter Counter-Measures (ECCM).

The AN/PYQ-10 Simple Key Loader (SKL) is a ruggedized, portable, hand-held fill device, for securely receiving, storing, and transferring data between compatible cryptographic and communications equipment.

2023年2月10日 · While the term 'key' is used generally to refer to the entire effect of cutting and filling the hole, keys work according to two signals: a key signal and fill signal. The key signal (or alpha channel, same thing) is the signal that cuts the hole. The fill signal is what fills the hole (what you actually see, like a lower third).

A minimized, lightweight key loader replacement for legacy key fill devices that delivers next generation capabilities—including the ability to connect and load keys in seconds.

Although DS-102 has been superceeded by DS-101, many devices are still backwards compatible with DS-102, making it arguably the most popular KEY FILL interface. DS-102 is used on many popular FILL devices, such as the KYK-13 and KOI-18 .

Key Fill Device (KFD) The KFDtool software supports KFD features through the KFDtool hardware adapter (TWI/3WI/Three Wire Interface), as well as through a IP (UDP) connection (DLI/Data Link Independent interface).

DS-101 is the current interface standard for electronic transfer devices, or fill units, developed and endorsed by the US National Security Agency. It superceedes the older DS-102 standard and is supported by nearly all modern radio sets and encryption devices, although most equipment is still backward compatible with DS-102.

Standard Key Fill enables users to create AES or DES keys, either manually or automatically, and deploy them to the active or the inactive keysets in a radio. Standard Key Fill can also perform an inventory check of the keys in a radio and may be used to switch between active and inactive key sets. A KFD loaded with both standard and fast key ...
