The Advanced Encryption Standard ( AES ), also known by its original name Rijndael ( Dutch pronunciation: [ˈrɛindaːl] ), [5] is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. [6]
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 ...
AES key schedule. The Advanced Encryption Standard uses a key schedule to expand a short key into a number of separate round keys. The three AES variants have a different number of rounds. Each variant requires a separate 128-bit round key for each round plus one more. [note 1] The key schedule produces the needed round keys from the initial key.
The other attack requires 2 116 known plaintexts and 2 121 memory but also requires 2 237.5 time. Serpent is a symmetric key block cipher that was a finalist in the Advanced Encryption Standard (AES) contest , in which it ranked second to Rijndael . [2]

A High Assurance Internet Protocol Encryptor ( HAIPE) is a Type 1 encryption device that complies with the National Security Agency 's HAIPE IS (formerly the HAIPIS, the High Assurance Internet Protocol Interoperability Specification). The cryptography used is Suite A and Suite B, also specified by the NSA as part of the Cryptographic ...
Advanced Encryption Standard process. The Advanced Encryption Standard (AES), the symmetric block cipher ratified as a standard by National Institute of Standards and Technology of the United States (NIST), was chosen using a process lasting from 1997 to 2000 that was markedly more open and transparent than its predecessor, the Data Encryption ...
CTR_DBRG typically uses AES. AES-CTR DRBG is often used as a random number generator in systems that use AES encryption. The NIST CTR_DRBG scheme erases the key after the requested randomness is output by running additional cycles. This is wasteful from a performance perspective, but does not immediately cause issues with forward secrecy.
