NAEPASC: A novel and efficient public auditing mechanism for cloud data

NAEPASC: A novel and efficient public auditing mechanism for cloud data

Research objective: With the extensive depth of cloud computing, more and more users choose cloud to store data. The integrity of the data in the cloud is difficult to determine because the user may not be able to save any copies of the data locally. In addition, the same user may need to store multiple copies of data into the cloud, so simplifying key management is also a key issue. This paper attempts to design an identity-based data integrity verification mechanism that satisfies the cloud storage environment to detect the correctness of the data in the cloud.

Innovative points: Referring to identity-based signature mechanism, an identity-based data integrity verification model is proposed, including private key generation server, user, cloud storage server and third party audit. This mechanism can not only detect data integrity effectively, but also simplify user key management, including key recovery and key storage. In addition, the protocol uses the public key for the user to disclose information, such as mail.

Important conclusion: The verification mechanism designed in this paper can effectively detect violations of user data integrity in the cloud. By considering the user's identity information, the user's key management is simplified, and the audit burden of the third party auditor is reduced. Safety Proof and safety test show that NAEPASC is a safe and efficient integrity verification mechanism.
