A Non-Conventional Scheme for Enhancing Security Level in Diffie Hellman Key Exchange Protocol
Customarily, secure encoded correspondence between two gatherings necessitated that they first trade keys by some protected physical channel, for example, paper key records moved by a confided in dispatch. The Diffie–Hellman key exchange strategy permits two gatherings that have no earlier information on one another to together set up a common mystery key over an uncertain channel. This key would then be able to be utilized to scramble resulting interchanges utilizing a symmetric key figure. However, the algorithm cannot be used for different key at both ends for key trade. One of the key threats is man in the middle. Herein lies the approach of key variability and we have studied different schemes of Diffie Hellman Key Exchange with variable key.
