An OTP Integrated Optimal Key RSA Based Secure Data Communication

Abstract

System security is a basic aspect of data sharing. Aspires have been made to exhaust particular defects over the web. For this, different creative usage and security methods have been made. The measure of information exchange isn't a factor. The major factor is, how much it's secure, the channel gives while transmitting information. Cryptography is one such structure, which grants secure information transmission without losing its protection and uprightness. In light of the key circulation, cryptography is also assembled into two critical forms Symmetric Key Cryptography as well as Asymmetric Key Cryptography. RSA is one of the best conspicuous public-key cryptography based algorithms is unequivocally utilized for encryption/decryption. It's far based on the logical arrangement of factorization of strongly enormous whole numbers which is a compute-intensive way. In this paper, we have provided a novel, secure and profitable information communication system dependent on the RSA algorithm. Mystery updating signal dealing with systems have been proposed in the exploration for the two data transmission and the channel estimation stages. The proposed one facilitates the advantages of both RSA calculation and One Time Password (OTP) produced by the sender and got just by the endorsed customer. Despite that not at all like conventional RSA algorithm, in this work we embrace perfect key assurance by particle swarm optimization (PSO) during both encryption and decryption. The use of PSO for perfect key decision makes the general technique proficient by extending the security level and making the computation procedure very easy.
