Analysis of Secure Privacy Data Sharing in Cloud Computing

Cloud computing is an emerging technology which relies on sharing of computing resources. Sharing of data in the group is not secure as the cloud provider cannot be trusted. The fundamental difficulties in distributed computing of cloud suppliers are Data security Resource scheduling and Energy consumption. Key aggregate cryptosystem is used to secure private/public data in the cloud. This key is consistent size aggregate for adaptable decisions of ciphertext in cloud storage. One time password approach (OTP) is secrete and secure password which is valid for one time sign-in. Virtual Machines (VMs) provisioning is effectively empowered the cloud suppliers to efficiently use their accessible resources and get higher benefits. To share data resources among the individuals from the group in distributed storage is secure flexible and efficient. Any data stored in different cloud data centers are corrupted recover using regenerative coding. Security is provided too many techniques like Forwarding security backward security Key-Aggregate cryptosystem Encryption and Re-encryption etc. The energy is reduced using Energy-Efficient VM’s Scheduling in Multi-Tenant Data Centers.
