Fraction of Data in a Secure Client-Server Communication Method Using Key Exchange

Secure communication is an interesting issue nowadays. While the fame of chat applications expands, this notoriety carries some security problems with it. An assortment of authentication mechanisms and encryption strategies recommended and applied between to limit the expanding security issues. Numerous analysts pick the best they found and use it in various mix to give security to the chat application. On the comparable terms, we have utilized a combination of key exchange calculation mixed with an encryption algorithm. This blend is alluded to as “Three-way system” since it guarantees all the three-protection plan of verification, data security and authentication, simultaneously. In this paper, we actualize a best in class client server hybrid model encryption framework utilizing DH algorithm combined with (AES) Advanced Encryption Standard encryption algorithm. Regardless of whether the key in transmission is cracked, the concept of Diffie Helman key exchange makes it futile, since key in transmission is of no utilization without client's private key, which is kept uniquely to the real client. This proposed design of three-way component makes it difficult for hackers to exploit the security framework, thereby securing the chat application.
