Secure communication protocol using embedded devices based on FPGA

This paper will describe a novel and secure communication protocol based on a hybrid System On Chip (FPGA Programmable Logic, plus Dual Core ARM Processing System) embedded architecture. Due to this System On Chip feature, the tasks for each component can be easily delimited, implemented and controllable. Taking in account the destination of the protocol: security and communication (which implies that computational speed is an important factor), this paper will deal with both security and speed aspects. The wide usage of this protocol can be applied beneath the presented one - simple instant messenger (chat) facility. Once the principles are understood, the embedded device can be used for a lot more types of communication.
