In NSA terminology, this stream of bits is called the key.

In NSA terminology, a Type 3 product is a device for use with Sensitive, But Unclassified ( SBU ) information on non-national security systems.

In cryptography, a Type 1 product is a device or system certified by the National Security Agency ( NSA ) for use in cryptographically securing classified U. S. Government information.

For a historically oriented list of NSA encryption products ( most of them Type 1 ), see NSA encryption systems.

Type 1 products contain approved NSA algorithms.

In cryptography, Type 2 products are unclassified cryptographic equipment, assemblies, or components, endorsed by the National Security Agency ( NSA ), for use in telecommunications and automated information systems for the protection of national security information.

Type 2 products may not be used for classified information, but contain classified NSA algorithms ( e. g. CORDOBA ) that distinguish them from products containing unclassified algorithms like DES.

: is representative of a family of encryption algorithms developed in 1980 as part of the NSA suite of " Type I " algorithms ... Skipjack was designed using building blocks and techniques that date back more than forty years.

Most STU-III units were built for use with what NSA calls Type 1 encryption.

Little is publicly known about the algorithms NSA has developed for protecting classified information, what NSA calls Type 1 algorithms.

In 2003, for the first time in its history, NSA approved two published algorithms, Skipjack and AES for Type 1 use in NSA approved systems.

In 2003, NSA certified AES for Type 1 use in some NSA-approved systems.

SAVILLE is an NSA Type 1 encryption algorithm.

* Type 1 key-( NSA ) keys used to protect classified information.

* Type 2 key-( NSA ) keys used to protect sensitive but unclassified ( SBU ) information.

A Type 1 Product refers to an NSA endorsed classified or controlled cryptographic item for classified or sensitive U. S. government information, including cryptographic equipment, assembly or component classified or certified by NSA for encrypting and decrypting classified and sensitive national security information when appropriately keyed.

In October, 2005 the New York Times reported that Robert J. Hanyok, a historian for the U. S. National Security Agency, had concluded that the NSA deliberately distorted the intelligence reports that it had passed on to policy-makers regarding the August 4, 1964 incident.

Reviewing the NSA's archives, Mr. Hanyok concluded that the NSA had initially misinterpreted North Vietnamese intercepts, believing there was an attack on August 4.

" Polarized Neutron Studies on Antiferromagnetic Single Crystals: Technical Report No. 4 ", Massachusetts Institute of Technology ( MIT ), Brookhaven National Laboratory, United States Department of Energy ( through predecessor agency the Atomic Energy Commission ), National Security Agency ( NSA ), Air Force Office of Scientific Research ( AFOSR ), ( Nov. 26, 1958 ).

The Skipjack algorithm was declassified and published by NSA on June 24, 1998.

In cryptography, Skipjack is a block cipher — an algorithm for encryption — developed by the U. S. National Security Agency ( NSA ).

Some accusations were made that the NSA had pressured the original designers into crippling CMEA, but the NSA has denied any role in the design or selection of the algorithm.

It contains an NSA approved security microprocessor called Capstone ( MYK-80 ) that implements the Skipjack encryption algorithm.

The information needed to initialize the algorithm, what most cryptographers today would call the key, NSA calls a cryptovariable.

In response, the NSA had modifications made to other units in the field, presumably changing the crypto algorithm in some way, perhaps by changing the shift register feedback taps.

NSA's certification of the unclassified NIST-selected AES algorithm for classified use " in NSA approved systems " suggests that, in the future, NSA may use more non-classified algorithms.

* generating key material for FIREFLY ( an NSA algorithm based on public key cryptography )

AES is available in many different encryption packages, and is the first publicly accessible and open cipher approved by the National Security Agency ( NSA ) for top secret information when used in an NSA approved cryptographic module ( see Security of AES, below ).

According to its website, the US National Security Agency ( NSA ) is " a high technology organization ... on the frontiers of communications and data processing ".

According to the article cited, the still classified NSA report is incorrect based on the CIA documents that were declassified which show that Powers ' account of being shot down at altitude was accurate.

The National Security Agency ( NSA ) is a cryptologic intelligence agency of the United States Department of Defense responsible for the collection and analysis of foreign communications and foreign signals intelligence, as well as protecting U. S. government communications and information systems, which involves information security and cryptanalysis / cryptography.

The NSA is directed by at least a lieutenant general or vice admiral.

NSA is a key component of the U. S. Intelligence Community, which is headed by the Director of National Intelligence.

The Central Security Service is a co-located agency created to coordinate intelligence activities and co-operation between NSA and other U. S. military cryptanalysis agencies.

By law, NSA's intelligence gathering is limited to foreign communications, although domestic incidents such as the NSA warrantless surveillance controversy have occurred.

It is located at NSA headquarters.

The scale of the operations at the NSA is hard to determine from unclassified data ; some 18, 000 parking spaces are visible in photos of the site.

General Donovan might have copied the papers before returning them the following January, but there is no record of Arlington Hall's receiving them, and CIA and NSA archives have no surviving copies.

The National Speakers Association ( NSA ) is a professional speakers ' organization that supports the pursuit of public speaking as a business.

** The AFSA ( predecessor of the NSA ) is established.

The SP3D protocol specification was published by NIST, but designed by the Secure Data Network System project of the National Security Agency ( NSA ), IPsec AH is derived in part from previous IETF standards work for authentication of the Simple Network Management Protocol ( SNMP ).

The Assistant to the President for National Security Affairs, commonly referred to as the National Security Advisor ( abbreviated NSA, or sometimes APNSA or ANSA to avoid confusion with the abbreviation of the National Security Agency ), is a senior official in the Executive Office of the President who serves as the chief advisor, stationed in the White House, to the President of the United States on national security issues.

NSA has been trying to replace this method with a more secure electronic key management system ( EKMS ), but paper tape is apparently still being employed.

:" NSA Security-enhanced Linux is a set of patches to the Linux kernel and some utilities to incorporate a strong, flexible mandatory access control ( MAC ) architecture into the major subsystems of the kernel.

DSA is covered by, filed July 26, 1991, and attributed to David W. Kravitz, a former NSA employee.

Louisiana Tech is one of only 35 comprehensive research universities in the nation and the only university in Louisiana to be designated as a National Center of Academic Excellence in Information Assurance Education and Research by the National Security Agency ( NSA ) and the United States Department of Homeland Security ( DHS ).

Ramsey is also the man the NSA sends out to retrieve Frank when the Ex-Seal makes unscheduled disappearances from the base.
