An Approach to Provide Safety over cloud using Efficient Encryption

Abstract

Cloud computing is a technology, which enables you to store the data remotely instead of local machines and access the stored data over the internet. This technology is getting overwhelming response from various fields, such as IOT where security is one of major concerned area. So, when our data is exposed to the outside world via internet then security should be provided to protect from an unauthorized access to the data stored on cloud. To protect the data when it is in- transit or at-rest the best mechanism is to encrypt the data. So, I had considered two mechanisms to secure the data stored on cloud. I had used two methods, first is AES and the second is Elgamal Encryption. At the end of this paper we compare these two methods by performance graphs using different parameters.
