Secure Data Storage Security in Public Cloud

Project Abstract / Summary : To protect outsourced data in cloud storage against corruptions, adding fault tolerance to cloud storage together with data integrity checking and failure reparation becomes critical. Recently, regenerating codes have gained popularity due to their lower repair bandwidth while providing fault tolerance. Existing remote checking methods for regenerating-coded data only provide private auditing, requiring data owners to always stay online and handle auditing, as well as repairing, which is sometimes impractical. In this paper, we propose a public auditing scheme for the regenerating-code-based cloud storage. To solve the regeneration problem of failed authenticators in the absence of data owners, we introduce a proxy, which is privileged to regenerate the authenticators, into the traditional public auditing system model. Moreover, we design a novel public verifiable authenticator, which is generated by a couple of keys and can be regenerated using partial keys. Thus, our scheme can completely release data owners from online burden. In addition, we randomize the encode coefficients with a pseudorandom function to preserve data privacy. Extensive security analysis shows that our scheme is provable secure under random oracle model and experimental evaluation indicates that our scheme is highly efficient and can be feasibly integrated into the regenerating-code-based cloud storage.

Why did you choose to work on this project topic : To protect our data's from out sources and keeping secure our data's in public cloud .in this project we using Encrypting and Decryption methodology when we were uploading and downloading our files in public cloud, for uploading and downloading files there OTP will be created by real time cloud(DropBox) .The data's will be splitting into three or four types while storing in cloud.

Project Highlights : I my project different one think so , using the mechanism Encryption and Decryption on both uploading and downloading the form cloud. For everything there is a Secret key will be generated by real time cloud(OTP-One Time password).
