We are implementing volume encryption using ESSIV mode, as discussed in Section 9.4.2. Which of the following statements are true about the implementation? Select all that apply.
Group of answer choices
a) The mode uses sector numbers to vary the information in the ciphertext.
d) The decryption process never uses block decryption.
b) Different initialization vectors are stored in different disk sectors.
c) All sectors use the same block cipher key.
e) Sectors are vulnerable to bit-flipping attacks.

Respuesta :

The sentence that is true about the implementation is Different initialization vectors are stored in different disk sectors. Thus, option (b) is correct.

What is encryption?

The technique of encoding information is known as encryption. The original representation of the information, known as plaintext, is converted into an alternate form known as ciphertext throughout this process.

Only authorized parties should be able to decrypt ciphertext into plaintext and retrieve the initial information.

Distinct initialization vectors are saved in different disk sectors when volume encryption is used in ESSIV mode. Therefore, it can be concluded that  option (b) is correct.
