Creating security in information by the aid of FEAL data coding algorithm through simulation & synthesis

Communications usually do not have enough security. One of the ways for making the data secure is using methods for coding the information in a special manner. In this article one of the algorithms of coding and decoding information has been reviewed and explained. Coding is converting information to the form of coded text and decoding is the operation of converting coded information to the original form. This algorithm can implement these two operations well with high confidence. Algorithm of coding data rapidly is called FEAL. All the parts of this algorithm such as themethod of the operations of this algorithm, method of producing key, method of producing accidental data and etc. have been reviewed. After the description of the general structure, method of its simulation by using the hardware description language VHDL have been reviewed and the results of its synthesis by another algorithm named DES in the framework of one comparison is being reviewed.
