Tunnel
Remember, with tunnel mode, encryption does not happen until just before it leaves the local network. Traffic
likely remains unencrypted between the end user device and the local network boundary.
A security analyst on a local network using monitoring tools is likely to only be able to read contents of traffic
encrypted using IPSec ______ mode.
A. Tunnel
B. Transport
C. Trusted
Chaskey
_____ is a lightweight cryptography method for signing messages (MAC). It boasts a relatively undemanding
hardware implementation (only ~3,333 gates required at 1MHz clock rate) making it suitable for IoT
implementation.
