Secure Data Transfer using Key Exchange Protocol based on Cloud

Abstract

The cloud is a very useful platform that is used to provide dynamic resources, which helps in virtualization and high availability. Since cloud computing rests on the internet, security issues like privacy, data security, confidentiality, and authentication are encountered. In order to get rid of the same, various encryption algorithms and mechanisms are used in different combinations. In similar terms, we chose to use multilevel encryption with the help of hybrid cryptographic algorithms to enhance the security of data on the cloud. We aimed at developing a web system which facilitates the text to be communicated to users securely by using Diffie-Hellman key exchange to exchange key to facilitate the exchange of the private key which is used to encrypt the data at the sender end and hence the same key will be used at the receiver end.
