Block cipher mode of operation - Wikipedia
The simplest of the encryption modes is the electronic codebook (ECB) mode (named after conventional physical codebooks [19]). The message is divided into blocks, and each block is encrypted separately.

Electronic Code Book (ECB) in Cryptography - GeeksforGeeks
2024年5月8日 · Electronic Code Book (ECB) is the simplest AES block cipher mode. A block cipher takes a fixed-size block of text (b bits) and a key and outputs a block of b-bit encrypted text. If the number of plaintexts to be encrypted is greater than b bits, then the block cipher can still be used by breaking the plaintext into b-bit blocks.
ECB Mode vs CBC Mode in Cryptography - GeeksforGeeks
2024年5月8日 · How Does ECB Mode in Cryptography Work? The Electronic Code Book (ECB) mode is one of the easiest and most effective algorithms to use as a simple replacement technique. The input plaintext is divided into blocks and encrypted separately with the key. This enables the decryption of each encrypted block independently.
