PP-CSA: A Privacy-Preserving Cloud Storage Auditing Scheme for Data Sharing

IEEE BASE PAPER ABSTRACT:

Data sharing is one important service provided by cloud storage. In order to share data conveniently and securely, Shen et al. proposed a cloud storage auditing scheme for data sharing, which uses the sanitizable signature to hide sensitive information. However, it may cause unauthorized access to the data, since anyone can access the data stored on the cloud server. This article proposes a privacy-preserving cloud storage auditing (PP-CSA) scheme for data sharing, where only authorized users can access the data. Furthermore, PP-CSA adopts the Diffie–Hellman protocol to avoid the secure channel between the data owner and the sanitizer. Finally, the security analysis and the experimental results prove that the security and efficiency of PP-CSA can be accepted.

PROJECT OUTPUT VIDEO:

EXISTING SYSTEM:

Shacham and Waters proposed a compact PoR based on BLS signature, which can support public integrity auditing. Furthermore, for cloud storage auditing, the security of the key is becoming increasingly important. Therefore, such as key-exposure resilience and key escrow have been proposed successively in the cloud storage auditing.
Zhao et al. proposed a privacy-preserving cloud storage auditing scheme, which uses a security out-sourcing algorithm to assist the DO to generate authenticators.
Han et al. proposed a lightweight privacy-preserving cloud storage auditing, which does not need bilinear pairing operations in the auditing phase.

DISADVANTAGES OF EXISTING SYSTEM:

The existing schemes have complex certificate management problems because they are based on public key infrastructure.
The existing system schemes have the DO’s sensitive information can be accessed in the above-mentioned cloud storage auditing schemes for data sharing.
In the existing system any users can access the sharing data in the scheme, which may cause the data abuse. Also, this scheme needs a secure channel between the DO and the sanitizer.

PROPOSED SYSTEM:

This system proposes a PP-CSA scheme for data sharing, where only the authorized user can access the data. This system makes a secure request when the DO sends auditing authenticators to the sanitizer. And there is no need to establish a secure channel between the DO and the sanitizer in PP-CSA. We give the security analysis, which proves that PP-CSA is a secure cloud storage auditing scheme with authorized access. Moreover, the experiment results show that PPCSA achieves desirable efficiency.
In this model, the DO first sends the ID to the KGC for registration, the KGC distributes private key for the DO. Then, the DO blinds the sensitive information in the data and generates authenticators. Finally, the DO sends blinded data and authenticators to the sanitizer. After receiving it, the sanitizer sanitizes the data and transfers corresponding authenticators. Afterward, the sanitized data and corresponding authenticators are uploaded to the CS for storage and sharing. When the user needs to use the data, a sharing request is sent to the sanitizer. The sanitizer generates authorization based on the DO’s warrant and sends it to the CS together with the sharing request. After passing the verification of the CS, the user can access the data.

ADVANTAGES OF PROPOSED SYSTEM:

Additional security is made in-extra with the user name and password for the Data owner, such that only if the KGC approves, the private key is sent to the Data owner, only if the private key is available, the data owner can login, which is an additional layer security to the system to prevent unauthorized logins.
Data Owner files are more secured.
Auditing proof gives more confident for the data owners about their file security.
No overloads.
More enhanced security for the cloud files.
