Wang, Motorola, and Xerox are also developing LAN encryption products.
I'm familiar the Xerox Encryption Unit: 802.3; it plugs into the drop 
cable between the processor and the transceiver connection; encryption 
is done using a chip developed by Ultron (703)827-9405; the first 14
octets remain in-the-clear; the  XEU costs about 5K; Xerox contact 
is Frank Presson (703)442-6777.
