device to the time it arrives at the receiver's device.
A. Tunnel
B. Transport

8. Chaskey is a lightweight cryptography method for signing
messages (MAC). It boasts a relatively undemanding
hardware implemen- tation (only ~3,333 gates required
at 1MHz clock rate) making it suitable for IoT
implementation.
9. 128 Chaskey has a key size of bits.
A. 256
B. 128
C. 80
10. salt A weakness of one-way hashing is that the same piece of
plaintext will result in the same ciphertext unless is
applied.
