Security for cloud computing data using a security cloud as a Third party auditor (TPA) A Survey

Abstract: Cloud computing is considered next generation architecture of IT Enterprise for co mputing. Cloud is nothing but the internet. Last 10 year ago peoples store their Credential data in data centre with firewall and used various security techniques used for protect the data but day by day the peoples data is increase and storing space is not enough for data storage since the data is stored anywhere across the global, the client organization have less control over the stored data. To build the trust for the growth of cloud co mputing the cloud providers must protect the user data fro m unauthorized access. For this one technique could be encrypting data on client side b efore store but in this technique burden for client is too much increase just like encrypting and decrypting data. Another techniques could be security services like co mputing hash, encryption/decryption service if provide for same cloud storage provider. We provide two cloud one for encryption and decryption namely Trusted third party which will provide security services and second one is for only storage. The software is only responsible for Encryption/decryption, computing/verifying Hash of data and does not store any data in trusted third party that is security cloud.

Keywords: Cloud co mputing, Encryption/decryption service (TPA), Hash service for Data verification and integrity check.
