Diffie–Hellman Key Exchange Protocols Enhanced

Abstract

ABSTRACT
Conversation is the crucial element in any type of network for making it viable to transfer data from one node to another. Conversation needs first-rate and security for higher performance and for acceptance of users and customer organizations. Value is dependent on length and some different elements of network but protection is very concern parameter in network as it is independent of network size and complexity. Security has come to be more important to non-public laptop customers, companies, and the army. Security became a major subject with the arrival of net and the history of protection allows a higher expertise of the emergence of safety generation. Ensuring secure communication over internet is extremely challenging because of the dynamic nature of the network and the lack of centralized management. The net shape itself allowed for many security threats to arise. The changed architecture of the internet can lessen the viable attacks that may be dispatched across the community. Understanding the assault methods, allows for the correct safety to emerge. records integrity is quite a difficulty in safety and to keep that integrity we tends to improve as to provides the better encryption processes for security. For this reason, Diffie–Hellman key agreement protocol is delivered for secure communique over community, but Diffie–Hellman key settlement protocol implementations have been plagued with the aid of severe protection flaws. The attacks may be very subtle and, more often than not, have not been taken into account by protocol designers. In our proposed work, we provide harder encryption with more desirable public key encryption protocol for safety, and proposed work may be carried out into any network to provide better protection. We have better the hardness in safety through improving the Diffie–Hellman encryption set of rules by adding some extra protection codes in cutting-edge set of rules. In our work discuss, both theoretical attacks against the Diffie–Hellman key agreement protocol and attacks based on implementation details and also, we have used a random parameter to make this algorithm more efficient. The random parameter generates new shared keys for each message that is exchanged between sender and receiver. So, different cipher text will be produced each time even for the same message. Thus, systems using this scheme will become more tolerant to various attacks.
