The VINSON
KY-58 is a secure voice
module primarily used to encrypt
radio communication
to and from military aircraft and other tactical vehicles. It is employed by U.S. Military Joint Services, NATO and some law enforcement agencies. It is designed to operate over bandwidth-restricted circuits such as UHF
and VHF
satellite access and wideband switched telephone systems. It uses the 16 kbit/s continuously variable slope delta modulation
(CVSD). The system was initially fielded as a replacement for the KG-36 and KG-34. The unit fits in a five inch cube and weighs about 5 pounds. Production ended in 1993.
VINSON
VINSON is a family of voice encryption devices used by U.S. and allied military and law enforcement, based on the SAVILLE encryption algorithm and 16 kbit/s CVSD audio compression. It replaces the Vietnam War-era NESTOR family....

Encryption
In cryptography, encryption is the process of transforming information using an algorithm to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information...

Communication
Communication is the activity of conveying meaningful information. Communication requires a sender, a message, and an intended recipient, although the receiver need not be present or aware of the sender's intent to communicate at the time of communication; thus communication can occur across vast...
