WPA2: What is the difference between AES and TKIP
AES mode support for FPGA (Xilinx, Altera, Microsemi Modes of AES - a short backgrounder. As stated previously, a "mode" is used to change the behaviour of the underlying block cipher (in this case AES), so that it has more useful properties. Modes are therefore a powerful way to enhance security, alter the behaviour of encryption in the face of data errors, or even to provide authentication Classic modes of operation for symmetric block ciphers Classic modes of operation for symmetric block ciphers¶. A block cipher uses a symmetric key to encrypt data of fixed and very short length (the block size), such as 16 bytes for AES.In order to cope with data of arbitrary length, the cipher must be combined with a mode of operation.. You create a cipher object with the new() function in the relevant module under Crypto.Cipher: How to choose between AES-CCM and AES-GCM for storage Performance costs 1 x AES operation and 1 x GHASH per block (GHASH generally faster than AES, so GCM is faster) Encrypt/decrypt of multiple blocks can be parallelized nicely GCM should be considered superior to CCM for most applications that require authenticated encryption.

Symmetric encryption — Cryptography 3.1.dev1 documentation
XTS mode is the most common if you are encoding a random accessible data (like a hard disk or RAM). OCB is by far the best mode, as it allows encryption and authentication in a single pass. However there are patents on it in USA. The only thing you really have to know is that ECB is not to be used unless you are only encrypting 1 block.

AES Encryption | Everything you need to know about AES
Special Publication 800-38F describes cryptographic methods that are approved for "key wrapping," i.e., the protection of the confidentiality and integrity of cryptographic keys. In addition to clarifying that some previously-approved methods are permitted for key wrapping, this publication specifies two deterministic authenticated-encryption modes of operation of the Advanced Encryption Standard (AES) algorithm: … (PDF) MODES OF OPERATION OF THE AES ALGORITHM AES is an algorithm for block encryption, which is in widespread use. Back in 2001, five modes of operation of the AES algorithm were standardized: ECB (Electronic Code Book), CBC (Cipher Block AES — PyCryptodome 3.9.8 documentation
