What is the difference between control channel and data channel when they describe what type of encryption they have?
Sorry for my reply. I'm also only F-Secure user (their home solutions).
Just as temporary suggestion (before good normal clarification/explanation from F-Secure):
Maybe such names as "Control" and "Data" channels with main meanings about design.
And based on article ... difference probably with view that "Control" can be much more important firstly.
Maybe also possible to re-check about "IKE" (for iOS) which there as "Control channel" (?!) - since it possible to find with 'direct' explanation.
I'm not friendly with VPN, but probably "Control channel" (and encryption) is something about certain 'protection' for VPN itself (as checks/improves for security status and usage).
And "Data channel" (and encryption) about certain data/traffic.
