Data Encryption Using a Microcontroller

Abstract

Encryption technology is the art of protecting information by converting it into specific symbols illegible texts called encrypted, and can not be solved only through a secret key is to break the encryption and converts it to plain text unreadable . . Purpose of encryption is to ensure the conservation of privacy and not to allow anyone to tamper with or viewed as either confidential or very special, no one can understand the substance of that information or messages, only to have its own secret key and that is through a process of decoding or data to the re-original form as plain text and require both encryption and decryption processes use some of the secret instructions commonly referred to as private keys and encryption techniques used by some of the key itself in the two processes, while those keys vary from one operation to another in the techniques of other advanced economies. This research touched on the History of encryption and the different types and has had a Caesar encryption method using the microcontroller, and the work program and a special chamber program. . The world is witnessing more attention to systems and encryption techniques in order to obtain safe systems to ensure information.
