Chapter 5 Pair Button and Reset Button 5.1 Pair (Secure with 128 bits-AES)
The Homeplug AV standard uses 128-bit AES (Advanced Encryption Standard) to safely transmit data
between powerline dvices. For the powerline devices to communicate with each other, they all need to
use the same Network Membership Key (NMK). Otherwise, they cannot unscramble the encrypted data
sent in the powerline network.
The Pair button allows you to set up a secure powerline connection with other HomePlug AV compliant
powerline devices which also support the Pair feature. Here takes TP-LINK powerline devices for
example (TL-WPA4220 for device A, TL-PA4010 for device B and C).
