SAVILLE
SAVILLE is a classified NSA Type 1 encryption algorithm, developed in the late 1960s, jointly by the Government Communications Headquarters (GCHQ) in the UK and the National Security Agency (NSA) in the US. It is used broadly, often for voice encryption, and implemented in many encryption devices. Little is known publicly about the algorithm itself due to its classified nature and inclusion in the NSA's Suite A. Some documentation related to the KYK-13 fill device and statements made by military officials confirm that SAVILLE has a 128-bit key, which consists of 120 key bits and an 8-bit checksum. Furthermore, it is known that SAVILLE has two modes of operation: Autonomous Mode (also known as Key-Auto-KEY or KAK) and Autoclave Mode (also known as Cipher-Text Auto Key or CTAK). On the AIM microchip, it runs at 4% of the clock rate (compare DES at 76% and BATON at 129%). The Cypris chip mentions two modes; specifications for Windster and Indictor specify that they provide ...

APCO Project 25
Project 25 (P25 or APCO-25) is a suite of standards for interoperable digital two-way radio products. P25 was developed by public safety professionals in North America and has gained acceptance for public safety, security, public service, and commercial applications worldwide. P25 radios are a direct replacement for analog UHF (typically FM) radios, but add the ability to transfer data as well as voice, allowing for more natural implementations of encryption and text messaging. P25 radios are commonly implemented by dispatch organizations, such as police, fire, ambulance and emergency rescue service, using vehicle-mounted radios combined with repeaters and handheld walkie-talkie use. Starting around 2012, products became available with the newer phase 2 modulation protocol, the older protocol known as P25 became P25 phase 1. P25 phase 2 products use the more advanced AMBE2+ vocoder, which allows audio to pass through a more compressed bitstream and provides two TDMA voice chann ...

VINSON
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 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 Items (CCI) when unkeyed and classified to the keymat of the key when going secure. VINSON devices include: * KY-57 * KY-58 * KY-68 * KY-99a (MINTERM) * KY-100 (AIRTERM) * KYV-2 * FASCINATOR VINSON is embedded into many modern military radios, such as SINCGARS. Many ...

National Security Agency
The National Security Agency (NSA) is a national-level intelligence agency of the United States Department of Defense, under the authority of the Director of National Intelligence (DNI). The NSA is responsible for global monitoring, collection, and processing of information and data for foreign and domestic intelligence and counterintelligence purposes, specializing in a discipline known as signals intelligence (SIGINT). The NSA is also tasked with the protection of U.S. communications networks and information systems. The NSA relies on a variety of measures to accomplish its mission, the majority of which are clandestine. The existence of the NSA was not revealed until 1975. The NSA has roughly 32,000 employees. Originating as a unit to decipher coded communications in World War II, it was officially formed as the NSA by President Harry S. Truman in 1952. Between then and the end of the Cold War, it became the largest of the U.S. intelligence organizations in terms of pers ...

Presidio (microchip)
A presidio ( en, jail, fortification) was a fortified base established by the Spanish Empire around between 16th and 18th centuries in areas in condition of their control or influence. The presidios of Spanish Philippines in particular, were centers where the martial art of Arnis de Mano was developed from Spanish cut-and-thrust fencing style. The term is derived from the Latin word ''praesidium'' meaning ''protection'' or ''defense''. In the Mediterranean and the Philippines, the presidios were outposts of Christian defense against Islamic raids. In the Americas, the fortresses were built to protect against raid of pirates, rival colonists, as well as Native Americans. Later in western North America, with independence, the Mexicans garrisoned the Spanish presidios on the northern frontier and followed the same pattern in unsettled frontier regions such as the Presidio de Sonoma, at Sonoma, California, and the Presidio de Calabasas, in Arizona. In western North America, a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
