modes—the Electronic Codebook (ECB) Cipher Block Chaining (CBC) Cipher Feedback (CFB) Output Feedback (OFB) and Counter (CTR) modes—can provide data confidentiality Two FIPS publications already approve confidentiality modes of operation for two particular block cipher algorithms
The traditional block cipher modes (CBC ECB CFB ) were defined a long time ago and do not adequately address some practical problems For example CBC is perfectly fine if the data is in multiples of the block size Unfortunately the commonly used padding together with CBC
