Layer 2 crypto device needed.

Hello, list

There are 2 remote offices and 2 links betwen them: fiber-optic and
twisted pair. And there are 2 separate VLANs in both offices, that's why
remote offices communicate on Layer 2 (Ethernet frame, especially
802.1q). The "primary" line is fibe-optic.
I want to create backup line for fiber-optic using twisted pair.
Fiber-optic link is terminated on switch, so I think that best way to
set-up backup line is to terminate twisted pair (using Ethernet bridges)
on the same switch and use STP for backup. But I think it's not secure sending Ethernet frames through twisted pair.

So the question is: does anyone know Layer 2 devices (like Ethernet bridges) with any crypto algs (with pre-shred key or smart card or anything else). I googled some time, but didn't find anything.

Thanks for all advises.
