Advanced Encryption Standard (AES): an encryption algorithm, selected by NIST after a public competition. In 2003, NSA certified AES for Type 1 use in some NSA-approved systems. Secure Hash Algorithm: a widely used family of hash algorithms developed by NSA based on earlier designs by Ron Rivest. Digital Signature Algorithm; Data Encryption ...
The vast majority of the National Security Agency's work on encryption is classified, but from time to time NSA participates in standards processes or otherwise publishes information about its cryptographic algorithms. The NSA has categorized encryption items into four product types, and algorithms into two suites.
NSA Suite B Cryptography was a set of cryptographic algorithms promulgated by the National Security Agency as part of its Cryptographic Modernization Program. It was to serve as an interoperable cryptographic base for both unclassified information and most classified information. Suite B was announced on 16 February 2005.
The Commercial National Security Algorithm Suite (CNSA) is a set of cryptographic algorithms promulgated by the National Security Agency as a replacement for NSA Suite B Cryptography algorithms. It serves as the cryptographic base to protect US National Security Systems information up to the top secret level, while the NSA plans for a ...
In cryptography, Skipjack is a block cipher—an algorithm for encryption—developed by the U.S. National Security Agency (NSA). Initially classified, it was originally intended for use in the controversial Clipper chip. Subsequently, the algorithm was declassified. [5]
The pad is generated via some algorithm, that expands one or more small values into a longer "one-time-pad". This applies equally to all algorithms, from insecure basic mathematical operations like square root decimal expansions, to complex, cryptographically secure pseudo-random random number generators (CSPRNGs).
The National Security Agency isn't just yearning for quantum computers that can break tough encryption -- it wants encryption that can protect against quantum computers, too. Officials have begun ...
Simon is a family of lightweight block ciphers publicly released by the National Security Agency (NSA) in June 2013. [5] [1] Simon has been optimized for performance in hardware implementations, while its sister algorithm, Speck, has been optimized for software implementations. [6] [7] The NSA began working on the Simon and Speck ciphers in 2011.
