10. Cipher Block Chaining prevents: (a) Cipher-text only attacks in Block ciphers. (b) Large number of rounds in Block ciphers. (c) Producing exactly same cipher-text block for two same plain-text blocks in Block ciphers. (d) All of the above.

Step 1
CBC is a mode of operation for block ciphers that combines each plaintext block with the previous ciphertext block before encryption. This ensures that identical plaintext blocks will produce different ciphertext blocks. Show more…
