A number of modes of operation have been designed to combine secrecy and authentication in a single cryptographic primitive. Examples of such modes are , integrity-aware cipher block chaining (IACBC) , integrity-aware parallelizable mode (IAPM), OCB, EAX, CWC, CCM, and GCM. Authenticated encryption modes are classified as single-pass modes or double-pass modes. Some single-pass … WebNov 6, 2024 · Electronic Codebook (ECB) Mode Electronic Codebook mode encrypts each block separately with the key. This always encrypts the identical plaintext into identical ciphertext blocks, thereby not hiding patterns well. Thus, we don't use it for cryptographic protocols. Decryption is also equally vulnerable to replay attacks.
