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.

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.

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.

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.

The operation of a cipher usually depends on a piece of auxiliary information, called a key ( or, in traditional NSA parlance, a cryptovariable ).

There was speculation at the time, however, that the NSA has deliberately reduced the key size from the original value of 112 bits ( in IBM's Lucifer cipher ) or 64 bits ( in one of the versions of what was adopted as DES ) so as to limit the strength of encryption available to non-US users.

Controversies arose out of classified design elements, a relatively short key length of the symmetric-key block cipher design, and the involvement of the NSA, nourishing suspicions about a backdoor.

There was some criticism from various parties, including from public-key cryptography pioneers Martin Hellman and Whitfield Diffie, citing a shortened key length and the mysterious " S-boxes " as evidence of improper interference from the NSA.

At the RSA Conference 2005, the National Security Agency ( NSA ) announced Suite B which exclusively uses ECC for digital signature generation and key exchange.

Hellman addresses the National Security Agency ’ s ( NSA ) early efforts to contain and discourage academic work in the field, the Department of Commerce ’ s encryption export restrictions, and key escrow ( the so-called Clipper chip ).

Section 508 § 1194. 3 General exceptions describe exceptions for national security ( e. g., most of the primary systems used by the National Security Agency ( NSA )), incidental items not procured as work products, individual requests for non-public access, fundamental alteration of a product's key requirements, or maintenance access.

The NSA established the EKMS program to supply electronic key to COMSEC devices in securely and timely manner, and to provide COMSEC managers with an automated system capable of ordering, generation, production, distribution, storage, security accounting, and access control.

Under an agreement with the US government, Lotus was allowed to start exporting 64 bit keys, so long as 24 bits of each key were recoverable using a special key issued by Lotus to the NSA.

( US export regulations were changed in 2001, so current versions of Lotus products are able to use longer keys and they no longer provide NSA with access to any key bits.

Fernandes published his discovery, touching off a flurry of speculation and conspiracy theories ; such as the second key, owned by the United States National Security Agency ( the NSA ), could allow the intelligence agency to subvert any Windows user's security.

It is maintained and safeguarded by Microsoft, and we have not shared this key with the NSA or any other party.

" Microsoft said that the key's symbol was " _NSAKEY " because the NSA is the technical review authority for U. S. export controls, and the key ensures compliance with U. S. export laws.

On the other hand, if Microsoft failed to think about the consequences of key loss and created a first key without using secret splitting ( and did so in secure hardware which doesn't allow protection to be weakened after key generation ), and the NSA pointed out this problem as part of the review process, it might explain why Microsoft weakened their scheme with a second key and why the new one was called _NSAKEY.

Microsoft denied that the NSA has access to the _NSAKEY secret key.

Because of the way the crypto verification occurs, users can easily eliminate or replace the NSA key from the operating system without modifying any of Microsoft's original

Since the NSA key is easily replaced, it means that non-US companies are free to install " strong " crypto services into Windows, without Microsoft's or the NSA's approval.

A demonstration program that replaces the NSA key can be found on Cryptonym's website.

Using the encryption key, the NSA discovers that Nikoladze has been using a network of unconventional relays to communicate with the Georgian military cells.

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.

The National Security Agency ( NSA ) defines a trusted system or component as one " whose failure can break the security policy ", and a trustworthy system or component as one " that will not fail ".
