Abstract:

Cloud Computing is evolving and considered next generation architecture for computing. Typically cloud computing is a combination of computing recourses accessible via internet. However in cloud computing, since the data is stored anywhere across the globe, the client organizations have less control over the stored data. One technique could be encrypting the data on client side before storing it in cloud storage, A trusted 3rd party cloud provider be used to provide security services, while the other cloud provider would be data storage provider. The trusted 3rd party security service provider would not store any data at its end, and its only confined to providing security service. The application or software will provide data integrity verification by using hashing algorithm like SHA-1,provide encryption/decryption using symmetric algorithm like AES, and defining band of people who can access the shared data securely can be achieved by defining access list. The encrypted data along and original data hash are stored in Separate Cloud (Security Cloud), therefore even if the storage cloud system administrator has access user data, since the data is encrypted it will be difficult for the system administrator to understand the encrypted data. While the user downloads the data from Storage Cloud, it is decrypted first and then new hash is calculated which is then compared with hash of original data stored in Security Cloud. Finally, this software/application provides the user with the ability to store the encrypted data in Storage cloud and hash and encryption/decryption keys in security cloud service, and no single cloud service provider has access to both.

Keywords:

Cloud computing; Hash service; encryption and decryption service; data protection
and integrity.
