Provable Dynamic Data in Cloud Computing Systems

Abstract

Steadily more and more companies are picking out outsourcing data to remote cloud service vendors (CSPs). Clients can appoint the CSPs storage infrastructure to store and get again close to endless amount of data through paying amount per month. On behalf of an improved level of scalability, availability, and sturdiness, some customers may want their data to be virtual on more than one servers throughout multiple data centers. The data owner stores the data in cloud service provider after the encryption. For securing the information Elliptic curve cryptography and Blowfish algorithms are used which is more secured than the advanced Encryption commonplace algorithm. By way of using at ease Hash Algorithm-1 owner can verify the integrity of the data. The data owner update probably the most copies from Cloud service provider and the rest data ought to be updated by using the Cloud service provider. By the way Message Authentication Code can be been up to date after which the client can send the request and receive the data from the Cloud service provider. With the aid of utilising the secure Hash Algorithm-1 the client can determine the integrity of the data, whether it is updated or not.
