The Suite B algorithms have been replaced by Commercial National Security Algorithm (CNSA) Suite algorithms: [7] Advanced Encryption Standard (AES), per FIPS 197, using 256 bit keys to protect up to TOP SECRET; Elliptic Curve Diffie-Hellman (ECDH) Key Exchange, per FIPS SP 800-56A, using Curve P-384 to protect up to TOP SECRET.
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 ...

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.
Algorithm Function Specification Parameters Advanced Encryption Standard (AES) Symmetric block cipher for information protection FIPS PUB 197: Use 256-bit keys for all classification levels. Elliptic Curve Diffie-Hellman (ECDH) Key Exchange Asymmetric algorithm for key establishment NIST SP 800-56A: Use Curve P-384 for all classification levels.
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.
