A Hybrid Algorithm For Enhancement of the Data Security during Network Transmission Based on RSA and DH

Abstract

Due to the tremendous technological transformation, more technologies and internet of things (IoT) devices are employed in today's digital world. The majority of these technologies are linked through a network. They produce enormous amounts of information at incredible speeds, leading to zillions of digital data moving via network connections. Maintaining comprehensive and high security for any exchangeable data is vital. Networked data need security and privacy. Multiple cryptographic techniques are currently available to maintain sending messages and data security. Regardless of its simplicity, private key cryptography is unproductive for authorization. As it often covers all of the components of information security, asymmetric cryptography is much more secure than private key encryption, but it takes much longer. The purpose of this paper is to demonstrate the few encryption techniques that are used on an insecure network to encrypt data. To encrypt the data, this paper proposes a new hybrid encryption technique. The suggested approach, MRSADH, encrypts and decrypts the data using Rivest, Shamir, and Adleman (RSA) and Diffie Hellman (DH) and produces the encoded data using the XOR function to be sent to the recipient in the shortest time and with high-security complexity compared to other methods in terms of performance and avalanche effect. The proposed study examines the two most widely used cryptographic algorithms, RSA and Diffie Hellman, and how they work and impact security and speed when integrated into a unified hybrid (MRSADH) computation with necessary adjustments. The study also presents a method that uses Asymmetric and Symmetric key encryption to improve data security while reducing the number of mathematical equations, which tends to result in a quicker execution time.
