5.x Ghz encryption

For our wireless backhaul what is the most efficient security protocal for speed and safety? As well as how to setup security in RouterOS 2.9 Winbox? Thanks for the assist.

read carefully, pay attention to configuration examples:

It shows how to set it BUT I do not see where it shows what is considered to be the MOST EFFICIENT protocal. I want security to be set for the wireless backhaul bridges that are WDS bridged.

isnt WDS a MT only thing like Nstream?

if it is then does it really need to be secured?
