odd spam in the system log? "kernel: wl0: random key value"

[Xruptor]

I have this spammed in my system log and I've been trying to track it down. Although I'm sure it's just a common feature and function of the router, I'm one of those curious types that likes to know where things are coming from.

Does anyone know what causes this type of spam in the system log?

"kernel: wl0: random key value"

It's not "spam", there's only 10 entries in 8 hours. It's just normal WiFi key renewal.

That was only just a small chunk of the log I posted. It's a lot more then what is shown, as I posted only an example. However thank you for the clarification on the function.
