Is HomePlug Powerline a low security way to transmit converted ethernet over ac powerlines?

Ethernet is encoded and put on the powerlines of a hotel lets say.

Then in the h otel rooms a device is used to get the encoded signal off the powerline and converted back to ethernet again.

But this signal is a signal that radiates as compared to a signal like VDSL that rides on the telephone lines of a hotel.

Both VDSL and HomePlug Powerline are two different ways to get ethernet to a hotel room.

But I'm suspicious about the security of the HomePlug powerline.

I believe it uses frequencies from around 4 MHz to around 10 Mhz? I might be off some on those frequencies. But they radiate.

As such someone could pick them up on a shortwave receiver and maybe decode them.

So while they might be a low cost way to get ethernet to a hotel room, it sure seems very low security to me.

Unless there is some special encryption going on.

Maybe someone can tell me how this works and if it is low security.

Thanks
