Security algorithm on Cloud Storage System

The cloud computing basic idea was given by 1960 by Professor John, "The future computers will be just like, the telephone services and according to requirement we use their services" and this computer idea has been play a vital role in industry". The combination of distributed, grid computing and virtualization is known as cloud computing, and these systems are interconnected group of systems and dynamically provision and offering the one or more unified cloud-computing resources. SLA is known as service level agreement and playing a vital role between clients and service provider. The SLA service level agreement is a negotiation between the users and cloud provider. The cloud service provider's objective is to provide their services, to clients qualitative, more secure, abrupt, scalable, more responsive, cost-efficient, on demand and automatically provisioned services just like: storage services, computation services, network system etc. Cloud services are geographically dispersed everywhere throughout the world in a transparent way and help to improve business execution by making a commitment to decrease the expense of conveying IT assets to any association. Cloud services implementation helping to reduce in a organization is controlling IT resources the cost. These cloud services demands are day by day rapidly increase as financial model applied in cloud computing is "Pay-per-Use".
