Data Security in Cloud for Medical Sciences using AES 512-bit Algorithm

Cloud computing is typically defined as a type of evaluation that relies on sharing computing resources to handle applications. There is a requirement to redesign the medical system to meet their better needs among the growing technologies .With the initiation of cloud computing the doctors can keep their information about the latest diseases, emergency cases and complex problems. However the privacy and security of data is extremely exigent. To guarantee privacy and security of data in cloud computing, we have proposed an effective approach for data security by the process of encrypting and decrypting the data through the concept of cryptography. In this paper the proposal is to prevent data access from cloud data storage centers by unauthorized access using AES-512 bit algorithm with key size and input block size of 512-bits that makes it more defiant to cryptanalysis.
