AES speed at 128, 192 and 256-bit key sizes. [clarification needed] [citation needed]Rijndael is free for any use public or private, commercial or non-commercial. [1] The authors of Rijndael used to provide a homepage [2] for the algorithm.
AES-NI (or the Intel Advanced Encryption Standard New Instructions; AES-NI) was the first major implementation. AES-NI is an extension to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008. [2] A wider version of AES-NI, AVX-512 Vector AES instructions (VAES), is found in AVX-512. [3]
ChaCha20-Poly1305 is an authenticated encryption with associated data (AEAD) algorithm, that combines the ChaCha20 stream cipher with the Poly1305 message authentication code. [1] It has fast software performance, and without hardware acceleration, is usually faster than AES-GCM .
AES is based on a design principle known as a substitution–permutation network, and is efficient in both software and hardware. [11] Unlike its predecessor DES, AES does not use a Feistel network. AES is a variant of Rijndael, with a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits.
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 .
A Type 1 Product refers to an NSA endorsed classified or controlled cryptographic item for classified or sensitive U.S. government information, including cryptographic equipment, assembly or component classified or certified by NSA for encrypting and decrypting classified and sensitive national security information when appropriately keyed.
The X86 architecture, as a CISC (Complex Instruction Set Computer) Architecture, typically implements complex algorithms in hardware. [10] Cryptographic algorithms are no exception. The x86 architecture implements significant components of the AES (Advanced Encryption Standard) algorithm, [1] which can be used by the NSA for Top Secret ...
The publication approves the XTS-AES mode of the AES algorithm by reference to the IEEE Std 1619-2007, subject to one additional requirement, which limits the maximum size of each encrypted data unit (typically a sector or disk block) to 2 20 AES blocks. According to SP 800-38E, "In the absence of authentication or access control, XTS-AES ...
