NSA has to deal with many factors in ensuring the security of communication and information (COMSEC and INFOSEC in NSA jargon): Confidentiality: making sure messages cannot be read by unauthorized parties. Authentication: the validation of the source of transmitted messages. Nonrepudiation: making sure that transmitted messages cannot be forged.
