![]() Hence, it provides more robust encryption as compared to ECB mode,īut it is a bit slower as compared to ECB mode. Plain text blocks are encrypted into dissimilar cipher text blocks. It requires IV to make each message unique meaning the identical The input plain text will be divided into blocks and each block will beĮncrypted with the key provided and hence identical plain text blocks are encrypted intoĬBC(Cipher Block Chaining) mode is highly recommended, and it is an advanced form of block cipher encryption. ![]() Different Modes of AES EncryptionĪES offers 2 different modes of encryption - ECB and CBC modes.ĮCB(Electronic Code Book) is the simplest encryption mode and does not require IVįor encryption.
