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 Chaining), CFB (Cipher FeedBack), OFB (Output FeedBack) and CTR (Counter).

ECB versus CBC Mode AES encryption The Advanced Encryption Standard (AES), is a block cipher adopted as an encryption standard by the U.S. government for military and government use. ECB (Electronic Codebook) is essentially the first generation of the AES. It is the most basic form of block cipher encryption.

Authenticated encryption - Wikipedia Six different authenticated encryption modes (namely OCB 2.0, Key Wrap, CCM, EAX, Encrypt-then-MAC (EtM), and GCM) have been standardized in ISO/IEC 19772:2009. More authenticated encryption methods were developed in response to NIST solicitation. Sponge functions can be used in duplex mode to provide authenticated encryption. The Advanced Encryption Standard and its modes of Even if AES behaves like an ideal block cipher, i.e., as a pseudo-random permutation on the 128-bit blocks on which the AES encryption function (also called the forward cipher function) acts -which would imply that AES is highly secure-, ECB mode, for example, is considered insecure. In this mode, if a message or block is repeatedly encrypted How to choose an Authenticated Encryption mode – A Few May 19, 2012
