تشفير البيانات الحية المنقولة بين نقطتي اتصال

Abstract EN

This research aims at designing a software system for communication and protecting a data and live information transmitted through a communication channel on both ends one is sender and the other is receptor by building a low-level software to deal with internal and external ports for data transfer.

In addition to design there is a software mechanism for the protection of this data and important information and confidentiality from spies using some encryption systems and decoding.

We implemented a method for programming the parallel port and then transported data to and from the processor and main memory, and vice versa for the purpose of processing.

We designing, building and implement a methods to process and the protect this data by using an encryption system of a collective of several different complexity encryption methods like additive, multiplicative, stream cipher and Nabsak by Markle-Hillman in a sent node (computer).

These methods are decoded after giving the public key and retrieving a clear information directly into the receiving node (computer).

The software system that has been designed and constructed is efficient, effective and easy to be used and it has the ability to transmit and store sent and received data and document them at high speed.
