Classified and sensitive communications over unsecured telephone systems alone represent such a lucrative and easy source of intelligence that NSA has undertaken a bold new approach to counter this threat. (U) Each of NSA's past efforts to develop and distribute COMSEC equipments to the field has taken many years to complete. To reduce this time signifi­ cantly NSA decided to tap the knowledge and resources of major commercial manufacturers of telecommunications equipment in a program called The Future Secure Voice System (FSVS) whereby NSA provides the cryptologic expertise and contractors provide technical, manufacturing, and marketing know-how. The goal is to design and produce a secure telephone the size of a conventional office deskset which will plug into a modular jack, cost less than 145, which directs that all U.S. Government systems $2,000, and be simple to operate. carrying classified information be secured, including telephone.

    Ky-57 Vinson

    KY-57 VINSON Homepage Crypto KY-57 (VINSON) Index Voice encryption unit Enigma The KY-57 was a wide-band voice encryption unit that was developed in the USA during the 1970s as a replacement of the NESTOR cryptographic products, such as the KY-38. It was suitable for use with a Hagelin wide range of military radios and telehone lines. As part of the VINSON family of devices, it was the main Fialka crypto 'workhorse' of the US Army during the 1980s. Even today, many radios and voice encryption devices are still backwards compatible with the KY-57, that is also known as the TSEC/KY-57. The Siemens airborne version of the KY-57 is called the KY-58. Philips The KY-57 uses the NSA-developed Type-1 KY-57 voice encryption unit Nema SAVILLE cryptographic algorithm. When used in combination with a radio transceiver, such as the Racal SINCGARS non-ICOM RT-1439/VRC, the KY-57 STK allows signal fades or losses for up to 12 seconds without losing synchronization. Transvertex The KY-57 was eventually superceeded by the KY- Gretag 99 that offered newer - more advanced - Telsy cryptographic algorithms, but that was still backwards compatible with the KY-57. Later Tadiran SINCGARS ICOM radios, such as the RT-1523, had built-in KY-57 (VINSON) compatibility. USA USSR Both voice and data can be encrypted with the KY-57. Voice data is digitized using Continuous Variable Slope Delta modulation (CVSD), similar to other voice crypto systems of the same era, such as the UK Philips Spendex-10 , the Spendex 50 and the Telsy TS-500.

    KY-58 (Vinson) The KY-57/58 is a member of the VINSON family. The VINSON family consists of wideband secure voice (WBSV) units developed by the National Security Agency to provide line of sight half-duplex voice and data encryption at 16 Kbps. The KY-57/58 provides security for AM/FM, VHF, UHF, half-duplex PTT combat net radios and tactical wireline systems when used with the HYX-57. Also used by non-tactical users for high-level communications in the local wideband telephone networks and wideband satellite terminals. The KY-57 is the manpack/vehicular model and the KY-58 is the airborne/shipborne version. The KY-57/58 is certified to pass data up to TOP SECRET and accepts key from the family of Common Fill Devices and also incorporates remote keying. KY-57/58 production was completed in 1993. No further production is planned. KY-58 photo by Tim Tyler Tim Tyler comments."The photo above depicts the KY-58 unit inside a USCG HH-65C 'Dolphin' helicopter taken in September 2008. It is currently configured just for use on their 225-400MHz aircraft band radio. Supposedly, they're in the process of upgrading the HH-65 helos into an MH-65 (Special Ops capable) configuration which will have APCO P-25 compliant radios (with AES crypto, for talking to other DHS agencies) as well as ANDVT / KY-100 type crypto for communicating with the military-side of USCG ops".

    Message from the Director, NSA The National Security Agency’s rich legacy of cryptologic success serves not only as a reminder of our past triumphs, but also as an inspiration for our future. Harry Truman, the man responsible for signing the legislation that brought our Agency into existence, was once quoted as saying, “There is nothing new in the world except the history you do not know.” Like all truisms, it is only partially accurate. Each generation of Americans must at some point deal with unforeseen problems and issues that transcend the status quo. Most would agree that the challenges faced by NSA in today’s war against terrorism are far different from those of World War II, Vietnam, or Desert Storm. Even so, President Truman was correct in his assertion that there is much to be learned from the past. The history of the National Security Agency has in many respects been based on and characterized by feats of intellectual brilliance. Pioneers like William Friedman, Frank Rowlett, Dr. Louis Tordella, and Agnes Meyer Driscoll, to name but a few, were able to build on past successes and do whatever was necessary to meet the challenges of their time. We should not forget, however, that NSA’s success is due not just to the efforts of the well- known legends of the cryptologic past, but also to the dedicated work of thousands of men and women whose names will never be noted in any history book. History tells us that both genius and hard work are required to ensure success.

    Encryption of Voice, Data and Video (Vdv) for Secure Terrestrial and Satellite Communications

    Dimov Stojce Ilcev / International Journal of New Technologies in Science and Engineering Vol. 2, Issue. 4,October 2015, ISSN 2349-0780 ENCRYPTION OF VOICE, DATA AND VIDEO (VDV) FOR SECURE TERRESTRIAL AND SATELLITE COMMUNICATIONS Stojce Dimov Ilcev Durban University of Technology (DUT), 133 Bencorrum, 183 Prince Street, Durban, South Africa Abstract: This paper introduces the Voice, Data and Video (VDV) encryption as protection shield for secure terrestrial and satellite communication systems deploying special hardware and software scrambling solutions against government or private surveillance and spying. The encryption covers fixed, personal and mobile (cellular) solutions including computer, fax and telex messaging modes for commercial and military applications. Keywords: Encryption, VDV/NSA, DES/AES, RSA/IBE I. INTRODUCTION Secure communication is when two entities are communicating and do not want a third party to listen in or to communicate in a way not susceptible to eavesdropping or interception. It includes means by which people can share mutual information with varying degrees of certainty that third parties cannot intercept what was said, heard, sent and saw. Other than spoken face-to-face communication with no possible eavesdropper, it is probably safe to say that no communication is guaranteed secure in this sense, although practical obstacles such as legislation, resources, technical issues (interception and encryption), and the sheer volume of communication serve to limit surveillance. In cryptography, encryption is the process of encoding voice (speech and fax), data (messages or text) and video (TV, videoconference and images) in such a way that only authorized parties can listen, read or see it properly. Encryption does not of itself prevent interception, but denies the speech, message and image content to the interceptor.

As requested by your office on July 26, 1985, this letter identifies the major issues regarding secure telephones that we have identified to date. The STU-II is the secure telephone in use today. These telephones are to be replaced by lower cost STU-III telephones. Development contracts for the STU-III telephones were awarded 'in March 1985 to AT&T, Motorola, and RCA to develop an easy to use, low cost (target price about $2,000) secure telephone, deliverable by early 1987. Current plans are to award production contracts to all three contractors (if they successfully develop a product) in March 1986, with deliveries to begin in April 1987. The number of units awarded to each contractor will depend on their price and degree of success in performance tests. A contract has also been awarded to GTE Sylvania for systems integration and testing. The total cost to the government for this developmental effort is about $82 million. This program is very unique because, in addition to having applicability to national security information, this secure telephone will also have a commercial market, that is, banks, brokerage firms, and other businesses interested in securing (395037) B-220762 their communications.
