Cipher Block Chaining

Counter

Galois/Counter Mode

Simplest

Divide plaintext into blocks, encrypts blocks using same key

Not recommended

Uses an IV for randomness when encrypting the first block

Combines each block with the previous using XOR

Suffers from pipeline delays as encryption is dependent on encrypting every previous block

Coverts a block cipher to a stream sipher

Combines an IV with a counter, uses results to encrypt each plaintext block

Each block uses the same IV but CTM combines it with the counter resulting in a different encryption for each block

Multiprocessor systems can encrypt/decrypt multiple blocks at the same time

Respected secure mode of operation

Represented as CTR or CM

Used by many block ciphers

Combines counter with galois method of authentication

Provides authenticity/integrity and confidentiality

includes hashing techniques for integrity

Widely used due to it's efficiency
