摘要：Cloud computing has been envisioned as the paramount solution to the rising storage device costs of IT Enterprises. With the high costs of data storage devices as well as the rapid rate at which data is being generated it proves expensive for enterprises or individual users to frequently update their hardware. Apart from reduction in storage costs data outsourcing to the cloud also helps in reducing the maintenance. Cloud storage moves the user's data to large data centers, which are remotely located, on which user does not have any control. However, this unique feature of the cloud rises many new security challenges which need to be clearly understood and resolved. One of the important concerns that need to be addressed is to assure the data integrity to customer. i.e. correctness of his data in the cloud. As the data is physically not accessible to the user the cloud should provide a way for the user to check if the integrity of his data is maintained or is compromised. In this paper a scheme is proposed which gives a proof of data integrity in the cloud which the customer can employ to check the correctness of his data in the cloud. This proof can be agreed upon by both the cloud and the customer and can be incorporated in the Service level agreement (SLA). This scheme ensures that the storage at the client side is minimal which will be beneficial for the organization.
