Secure Cryptography with ngDH protocol along with RSA & AES Algorithm

Abstract—RSA cryptography is an asymmetric communication protocol, and, AES the most used symmetric-key both are facing cryptanalysis attacks.. The famous key exchange protocol Diffie-Hellman; but it has issue of Logjam attack that allows man-in-middle in Diffie-Hellman. Thus, we combine RSA, AES, and Diffie-Hellman algorithm to provide security on called next generationDH or ngDH. Our objective Algorithm. Therefore, ngDH does not share data publicly with intended party. Instead, encrypts all shareable time by encrypting using algorithm. uses RSA retrieves public avoid a man-in-the-middle attack. demonstrate how defeat various kinds attacks.
