This new attack, by Alex Biryukov, Orr Dunkelman, Nathan Keller, Dmitry Khovratovich, and Adi Shamir, is against AES-256 that uses only two related keys and 2 39 time to recover the complete 256-bit key of a 9-round version, or 2 45 time for a 10-round version with a stronger type of related subkey attack, or 2 70 time for an 11-round version ...
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.
An AES instruction set includes instructions for key expansion, encryption, and decryption using various key sizes (128-bit, 192-bit, and 256-bit). The instruction set is often implemented as a set of instructions that can perform a single round of AES along with a special version for the last round which has a slightly different method.
As of October 2012, CNSSP-15 [4] stated that the 256-bit elliptic curve (specified in FIPS 186-2), SHA-256, and AES with 128-bit keys are sufficient for protecting classified information up to the Secret level, while the 384-bit elliptic curve (specified in FIPS 186-2), SHA-384, and AES with 256-bit keys are necessary for the protection of Top ...

Key management takes place within the hard disk controller and encryption keys are 128 or 256 bit Advanced Encryption Standard (AES) keys. Authentication on power up of the drive must still take place within the CPU via either a software pre-boot authentication environment (i.e., with a software-based full disk encryption component - hybrid ...
Advanced Encryption Standard (AES) Symmetric block cipher for information protection FIPS PUB 197: Use 256-bit keys for all classification levels. Module-Lattice-Based Key-Encapsulation Mechanism Standard (ML-KEM aka CRYSTALS-Kyber) Asymmetric algorithm for key establishment FIPS PUB 203: Use ML-KEM-1024 parameter set for all classification levels.
Like other AES submissions, Serpent has a block size of 128 bits and supports a key size of 128, 192, or 256 bits. [4] The cipher is a 32-round substitution–permutation network operating on a block of four 32-bit words. Each round applies one of eight 4-bit to 4-bit S-boxes 32 times in parallel.
