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