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.

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.

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).

Feb 10, 2023 · 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.

KYK-13 is a portable battery-powered device for the distribution of cryptographic key material — in particular Transmission Encryption Keys (TEKs) — introduced in 1976 by the US National Security Agency (NSA). The device is suitable for keys with a maximum length of 128 bits and follows the NSA'a DS-102 key transfer protocol.

The user-friendly, ruggedized, depot repairable RASKL device is the low cost, modern, Type 1 key fill solution. The ReAlly Simple Key Loader is the leader in next-generation key loading. It implements a one button key squirt to fill your secure communication equipment.

fill At the rear left corner of the CYZ-10 is a 6-pin U-229 connector (actually a U-283/U). By means of a fill cable, this receptacle can be connected to a crypto device, to a key transfer device like the KYK-13 , or to another CYZ-10.

The KIK-30 "Really Simple Key loader" (RASKL) is a fill device made by Sypris Electronics and approved by the US National Security Agency for the distribution of NSA Type 1 cryptographic keys.
