The NSA headquarters includes a cafeteria, a credit union, ticket counters for airlines and entertainment, a barbershop, and a bank. The employees at the NSA headquarters reside in various places in the Baltimore-Washington area , including Annapolis , Baltimore, and Columbia in Maryland and the District of Columbia, including the Georgetown community.
Following a major power outage in , in and in follow-ups through , The Baltimore Sun reported that the NSA was at risk of electrical overload because of insufficient internal electrical infrastructure at Fort Meade to support the amount of equipment being installed. This problem was apparently recognized in the s but not made a priority, and "now the agency's ability to keep its operations going is threatened.
Meade in , and expected that an increase of 10 to 15 megawatts would be needed later that year. Meade was Maryland's largest consumer of power. NSA held a groundbreaking ceremony at Ft. NCSC was responsible for computer security throughout the federal government.
As of , NSA collected intelligence from four geostationary satellites. NSA had installations in several U. In , to protect its assets and access more electricity, NSA sought to decentralize and expand its existing facilities in Ft.
Meade and Menwith Hill,  the latter expansion expected to be completed by The Yakima Herald-Republic cited Bamford, saying that many of NSA's bases for its Echelon program were a legacy system , using outdated, s technology.
A NSA report indicates that the ECC is responsible for the "largest analysis and productivity in Europe" and focuses on various priorities, including Africa, Europe, the Middle East and counterterrorism operations.
Thailand is a "3rd party partner" of the NSA along with nine other nations. It presumably eavesdrops on foreign embassies, governmental communications, and other targets of opportunity.
Its mission was to eavesdrop on the radio traffic of Chinese army and air force units in southern China, especially in and around the city of Kunming in Yunnan Province. Back in the late s the base consisted only of a small CDAA antenna array that was remote-controlled via satellite from the NSA listening post at Kunia, Hawaii , and a small force of civilian contractors from Bendix Field Engineering Corp.
The base apparently fell into disrepair in the s as China and Vietnam became more friendly towards the US, and by archived satellite imagery showed that the PUSHER CDAA antenna had been torn down, perhaps indicating that the base had been closed. It is likely that the NSA presence at Khon Kaen is relatively small, and that most of the work is done by civilian contractors. NSA has been involved in debates about public policy, both indirectly as a behind-the-scenes adviser to other departments, and directly during and after Vice Admiral Bobby Ray Inman 's directorship.
NSA was a major player in the debates of the s regarding the export of cryptography in the United States. Restrictions on export were reduced but not eliminated in Its secure government communications work has involved the NSA in numerous technology areas, including the design of specialized communications hardware and software, production of dedicated semiconductors at the Ft. Meade chip fabrication plant , and advanced cryptography research.
For 50 years, NSA designed and built most of its computer equipment in-house, but from the s until about when the U. Congress curtailed the practice , the agency contracted with the private sector in the fields of research and equipment.
NSA was embroiled in some minor controversy concerning its involvement in the creation of the Data Encryption Standard DES , a standard and public block cipher algorithm used by the U. There was suspicion that these changes had weakened the algorithm sufficiently to enable the agency to eavesdrop if required, including speculation that a critical component—the so-called S-boxes —had been altered to insert a " backdoor " and that the reduction in key length might have made it feasible for NSA to discover DES keys using massive computing power.
It has since been observed that the S-boxes in DES are particularly resilient against differential cryptanalysis , a technique which was not publicly discovered until the late s but known to the IBM DES team. This small modification was suggested by NSA two years later, with no justification other than the fact that it provides additional security.
An attack for SHA-0 that does not apply to the revised algorithm was indeed found between and by academic cryptographers. Because of weaknesses and key length restrictions in SHA-1, NIST deprecates its use for digital signatures , and approves only the newer SHA-2 algorithms for such applications from on.
A new hash standard, SHA-3 , has recently been selected through the competition concluded October 2, with the selection of Keccak as the algorithm. The process to select SHA-3 was similar to the one held in choosing the AES, but some doubts have been cast over it,   since fundamental modifications have been made to Keccak in order to turn it into a standard.
National Institute of Standards and Technology 's guidelines. This led to speculation of a backdoor which would allow NSA access to data encrypted by systems using that pseudo random number generator. This is now deemed to be plausible based on the fact that output of next iterations of PRNG can provably be determined if relation between two internal elliptic curve points is known.
Because of concerns that widespread use of strong cryptography would hamper government use of wiretaps , NSA proposed the concept of key escrow in and introduced the Clipper chip that would offer stronger protection than DES but would allow access to encrypted data by authorized law enforcement officials.
NSA has the ability to file for a patent from the U. Patent and Trademark Office under gag order. Unlike normal patents, these are not revealed to the public and do not expire. However, if the Patent Office receives an application for an identical patent from a third party, they will reveal NSA's patent and officially grant it to NSA for the full term on that date. One of NSA's published patents describes a method of geographically locating an individual computer site in an Internet-like network, based on the latency of multiple network connections.
The heraldic insignia of NSA consists of an eagle inside a circle, grasping a key in its talons. Carter USA ordered the creation of a device to represent the agency.
