| 1- Exchange pre-shared key: CKN + CAK | CKN or Connectivity Association Name |
| (same bot end) | CAK or Connectivity Association Key |
| >> Secure channel created for exchange of the SAK | |
| One will become the Key-server | use the MKA Macsec Key Agreement Protocol |
| 2- key-server will send the SAK | SAK or Security Association key |
| Will create 2 channels: Tx and Rx | |
