Abstract

Information security is the biggest and most complex problem at present because of its great impact on modern software in all fields. Therefore, many researchers are working to develop modern methods of protecting data from modification or theft or even accessing it in one way or another. As dealing with data is a very sensitive matter in terms of sending this data from one party to another through the Internet or social media. The protection of that data requires the use of algorithms to encrypt or conceal the data with the proposed and used algorithms, and these algorithms work based on the proposed key exchange principle, so many of these algorithms need a key generator to work with other than the key is public or private for encryption or decryption the blade. Our proposed developed a key generation sub-system, as this system consists of two parts, the first part aimed to generate the first key (the first 64-bit subkey), while the second part (the second subsystem) will generate the second key (the second subkey is 64-bit). As the two sub-systems work to generate keys in different ways, the first system uses the principle of electronic gates to generate the keys randomly, while the second system uses binary text and LFSR. The idea in these sub-systems is that they work together in encrypting and decrypting data, requiring that the sender and receiver have the keys to complete the process. The results obtained from the two subsystems show the power in protecting data from reading or decoding its code, as the message consists of only a part of the key and the second part is at the receiver, and this gives stronger immunity in this encrypted data.
