Security Model for Securing Data on Cloud

Data storage is transitioning from physical servers to “cloud” storage because cloud service providers deliver the resources through the Internet when required. Cloud computing is a successful and rapidly evolving technology. With new features and capabilities released regularly, companies can move to the cloud on a “pay as you go” model. The most prominent feature of pay as you go model on the cloud is that it is cost-effective, however, this makes the cloud platform vulnerable to cyber attacks. This is the reason, the safety of such information has become a concern. This paper provides a security framework that secures cloud storage from unauthorized individuals by using user identification and authorization. We have used dual encryption by using Advance encryption standard (AES) & Ecliptic Curve Cryptography (ECC). The double encryption makes the cloud environment resilient against different security attacks. The experimental results show that the proposed model has low computing costs.
