Abstract

This era is called the era of communications and the revolution of information technology. One of the most important things for which many accounts are counted is the protection of this information and the provision of a secure communication network for the transmission of information. At a time when information has become a commodity to be bought and sold, the more important the information, the higher its price. There was an increasing need to find a way to provide protection for this information.

    The science of cryptography or hiding information was not a product of the present. Rather, it has been used for several centuries, and it was called encryption or concealment, meaning that there was no difference between them as if it were one concept, but today this science has developed and expanded until it was classified and divided and put ways and means for it. Cryptography has become a field in itself, as well as concealment, and its applications have become extensive in the fields of e-commerce, medicine, the military field and other sciences.
