MULTI KEY ALGORITHM FOR SECURITY ENHANCEMENT OF RSA ALGORITHM USING MATLAB

Abstract

In this paper, a new technique is deployed to afford a strong secure algorithm based on dynamic keysstrategy to enhance the security of network against cyber- attacks. The objective of this technique is to provideconfidentiality and authentication of data between any partners. The proposed technique takes Multiple keys pair(Public and Private) with RSA algorithm which every key pair used to ensure the security of one communicationsession. Where the proposed technique enhances the communication system by defining a set of ciphers such thatnot only the key but also the cipher changes on every new data transaction. Simulation results have been achievedusing MATLAB R2014a; Single Key RSA (SK- RSA) and proposed Multi Keys RSA (MK- RSA) are comparedanalysis is made on execution time and secrecy of the communication system. Hence, deploying the MK- RSAalgorithm is proving more secure than SK- RSA algorithm
