How much information can you recover by decrypting the corrupted file, if the encryption mode is ecb, and cbc, respectively?

1 answer:

8 0

In the ECB mode, only one block is affected when any problem in a cipher text happens; moreover, each block is decrypted independently. However, the corrupted bit of the 30th byte in cipher text block 8 bytes might spread to all n bits in plaintext block.

The Electronic Codebook (ecb) means the first generation of the AES. This is the most basic form of block cipher encryption. The Cipher Blocker Chaining (CBC) means the advanced form of block cipher encryption. With the Cipher Blocker Chaining mode encryption, each ciphertext block is dependent on all plaintext blocks processed up to that point.
