WebYes, AES-CBC encryption still has to be done sequentially. AES-NI can only help with one encryption or decryption, but it still greatly increases the speed, because the encryption or decryption is the slowest part of CBC mode. (For the sake of completeness: You can use AES-NI for every encryption mode, not only CBC.)

WebApr 5, 2024 · Cipher block chaining or CBC is an advancement made on ECB since ECB compromises some security requirements. In CBC, the previous cipher block is given as input to the next encryption algorithm after XOR with the original plaintext block.

In cryptography, a cipher block chaining message authentication code (CBC-MAC) is a technique for constructing a message authentication code (MAC) from a block cipher. The message is encrypted with some block cipher algorithm in cipher block chaining (CBC) mode to create a chain of blocks such that each block depends on the proper encryption of the previous block.
