The National Security Agency (NSA) is the United States's cryptologic organization. An agency within the Department of Defense, it is believed to be the largest U.S. government intelligence gathering agency.

Responsible for the collection and analysis of foreign communications, it coordinates, directs, and performs highly specialized activities to produce foreign signals intelligence information. This involves a significant amount of cryptanalysis. It's also responsible for protecting U.S. government information systems and communications from similar agencies elsewhere, which involves a significant amount of cryptography.

Its eavesdropping mission includes radio broadcasting, both from various organizations and individuals, the Internet, telephone calls, and other intercepted forms of communication. Its secure communications mission includes military, diplomatic, and all other sensitive, confidential or secret government communications.

NSA employs the country's premier codemakers and codebreakers. It is said to be the largest employer of mathematicians in the United States and perhaps the world. Its mathematicians contribute directly to the two missions of the Agency: designing cipher systems that will protect the integrity of U.S. information systems and searching for weaknesses in adversaries' systems and codes.
