'''VINSON''' is a family of voice encryption devices used by U.S. and allied military and law enforcement, based on the [[National Security Agency|NSA's]] classified [[NSA Suite A Cryptography|Suite A]] [[Saville (cipher)|SAVILLE]] [[encryption algorithm]] and 16&nbsp;kbit/s [[Continuously variable slope delta modulation|CVSD]] [[audio compression (data)|audio compression]]. It replaces the [[Vietnam War]]-era [[NESTOR (encryption)|NESTOR]] (KY-8/KY-28|28/KY-38|38) family.

These devices provide [[:wikt:tactical|tactical]] [[secure voice]] on [[Ultra High Frequency|UHF]] and [[Very High Frequency|VHF]] [[Line-of-sight propagation|line of sight]] (LOS), UHF SATCOM [[communication]] and tactical phone systems. These terminals are [[unclassified]] [[Controlled Cryptographic Item]]s (CCI) when unkeyed and classified to the keymat of the key when going secure. 

VINSON devices include:

* [[KY-68]] {{fact|date=January 2016}}
* [[KY-99a]] (MINTERM)
* KY-100 (AIRTERM)
* [[KYV-2]]
* [[FASCINATOR]]

VINSON is embedded into many modern military radios, such as [[SINCGARS]]. Many multi-algorithm [[COMSEC]] modules are also backwards-compatible with VINSON.{{Citation needed|date=February 2008}}
