Step by step
Solved in 2 steps
- In terms of the number of encryption operations required to transfer a large file, compare cypher block chaining versus cypher feedback mode. How much more efficient is one than the other, and how much more efficient is one?In terms of the amount of encryption operations required to send a large file, compare cypher block chaining to cypher feedback mode. Which one is more efficient, and how much more efficient?Compare cypher block chaining versus cypher feedback mode in terms of the number of encryption operations necessary to deliver a large file. Which of the two is more efficient, and by how much?
- This may be used to explain why some block cypher modes of operation rely solely on encryption, while others combine encryption and decryption:In whole-disk encryption, what role does a TPM play?In modern encryption, plaintext is encoded in binary form. Each bit in a bit stream is encrypted into its matching ciphertext, while bits in a block stream are grouped together to create groups of bits prior to encryption.
