NAS or supplicant?  a supplicant never talks to the RADIUS - its all done
via the NAS. 

there are plenty of options to you - you already have thought about one
method - use a VPN (DTLS/IPsec based...up to you) to tunnel the RADIUS though.

or , if the NAS can do it, think about RADSEC - FreeRADIUS 3 supports 
RADSEC and its the way to go unless you want to forget RADIUS and use DIAMETER
instead.
