Is it Possible about embedded tcp stack???

P: 12
Hi, All
I want have a project related to network security. is my given supposition is right.
I put my programmed "Device" with my computer, and on each packet receive event by "Device", I wrap a udp packet around the received packets after encryption. forward this udp packet to my second programmed "Device" which then gets data of udp packet decrypt that and put that packet on the wire which is attached with to the second computer.
Actually I want to encrypt all traffic and pass through public links to a specific point(e.g. specific switch).So, that public users across the way cannot access the actual packet from computer a to computer b.
Example:
if my computer wants to send VoIP packet to a pc(on a specific switch).I get the packet bytes XOR them with a byte(encrypt) and send this packet using udp to the my another programmed device which gets udp packet, decrypt that, gets original bytes of voip packet and send it on the wire.the underlined situation is possible?.
and what would be the other complications in it?
Kind Regards,
Jon.
