Distributed Authentication for Federated Clouds in Secure Cloud Data Storage

Objective: The main objective of our approach is to define federative cloud environment set up and define security considerations of each user independently in a multi-cloud data storage. Methods/Statistical Analysis: For secure data outsourcing in cloud data storage, we propose to use (KASE) Key Aggregate Searchable Encryption for aggregate key based data sharing in the cloud. But KASE is the single key based policy for data sharing in single cloud. We extend KASE to multi cloud storage with Reliable Reasoning Power (RRP) for protection of the federative cloud environment. Findings: By applying above two methods in cloud setup, we find two basic parameters as advantages, i.e. 1. Aggregate Key based data sharing in the cloud with efficient and reliable data security. 2. Data storage and security for single user in federative cloud environment. Applications/Improvement: Our proposed methodology achieves following applications when compare to conventional methodology (i.e. KASE) i.e., 1. With respect to time RRP performs effective file uploading when compare to KASE. 2. Security and Data storage in RRP is efficient (whenever we consider server performance).
