A Comparative Analysis of Hybrid Encryption Technique for Images in the Cloud Environment

Cloud heralds a new era of computing. Cloud provides flexible, cost effective service. Cloud service is also referred as “On Demand Service” or “Pay as you go Service”. Mobile cloud computing is emerging branch of cloud computing which delivers services to mobile devices. As the smart phone usage has tremendously increased, the multimedia information such as pictures and video that is downloaded/uploaded from the cloud has also seen the rise. As our personal/sensitive information is with the third party, however, a significant question is, can we trust the cloud? There are many traditional security approaches are available to secure the data exchange between the users and the media cloud. But still there are instances of security breaches. This paper addresses the issues of security. Here we are proposing a hybrid encryption technique to secure the images. The scheme uses Elliptic Curve Cryptography to generate the secret key, which in turn used for DES and AES algorithms.
