Encryption and Decryption of Data by Using Geffe Algorithm

In this modern world of communications, cryptography has an important role in the security of data transmission and is the best method of data protection against passive and active fraud. In this paper, the authors used the stream cipher which is the best way with the algorithm Geffe generator with a specific length to encryption the information from plain text in the first compute. This has been sent via the cable which called RS-232 standard interface, which connected between the two computers, and receiving the cipher text in the second computer, and then it will be decryption by added the same algorithm to the cipher text to return to the plain text.
