Achieve reliable and confidential message using Pretty Good Privacy (PGP) algorithm

Abstract

The paper aims at verifying the reliability of the exchanged data and information. The study conducted using the Pretty Good Privacy (PGP) algorithm application within a network of computers. It proposed to provide a method to achieve reliability, using digital signatures and a suitable algorithm for pressing the data before sending it By information security and cryptography, the study assumes the possibility of achieving reliable and confidential information handled electronically. Algorithms using different pressing and digital signatures as well as giving a method for encryption . Enhance reliability algorithm being superior privacy and verification of confidentiality applied. The research has come to several conclusions, most notably: reduction of statistical information limiting the code analyst, reduce the size of the text to speed up the encryption process, access to the highest level of security; and synthesis applied to programs with ready-made structural language adopted in this area
