Ensuring data storage security through a novel third party auditor scheme in cloud computing

摘要

Cloud computing technology has been looked upon as the next-generation architecture of IT solution. It enables the users to move their data and application software to the network which is different from traditional solutions. Due to this IT services are not under logical, physical and users' controls, it brings many new different security challenges. Ensuring data storage security is one more urgent of them. The representative network architecture for cloud data storage includes a third party auditor which affords trustful authentication for user to operate their data security in cloud. In this paper, we study the problem of data storage security in cloud computing. A novel third party auditor scheme is proposed. The obvious advantage of our scheme is the cloud service provider can offer the functions which were provided by the traditional third party auditor and make it trustful. So it indeed reduces the constitution's complexity in Cloud Computing.
