Abstract: Communication is the basic process of exchanging information. The effectiveness of computer communication is mainly based on the security aspects whether it is through internet or any communication channel. The aim of this paper is based on analyzing the results given by Wiener’s, who says that if the private exponent d used in RSA cryptosystem is less than n^.292 than the system is insecure. We will focus on the result given by Weiner’s and try to increase the range of private exponent d up to n^0.5. As n is the product of p & q (which are the relative prime numbers). This paper also aims at considering the different factors that affects the performance of encryption algorithms so as to make our information more secure over the network.

Keywords: Conjunctive Normal Form (CNF), Cryptanalysis, RSA Algorithm, , SAT Solver tool.
