    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.

  • NSIAD-86-7 Concerns Regarding the National Security Agency Secure Telephone Program
    1 II UNITED STATES GENE& ACCGWT~NGOFFICE WASHINGTON, D.C. 2Q548 NATIONAL SECURITY AND IMIERNATIONAL AFFAlRS DlVlS1ON OCf 15 1985 IIIll IIll,ll~~ B-220762 128229 The Honorable Glenn English Chairman, Subcommittee on Government Information, Justice, and Agriculture ' Committee on Government Operations House of Representatives Dear Mr. Chairman: Subject: Concerns Regarding the National Security Agency Secure Telephone Program (GAO/NSIAD-86-7) On September 24, 1984, you requested that we evaluate the use of TEMPEST and similar technologies--such as secure telephones-- for the protection of national security information. 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.
