Suppose two plaintext samples P and Q are encrypted using a block cipher with the same secret key K and the same initialization vector IV (or nonce) for those modes that require it. Suppose each plaintext sample is divided into 100 blocks (including padding). If all the plaintext blocks of P and Q are the same, except for block 10, in which they differ by 1 bit, compare the corresponding ciphertext for each block cipher mode ECB
