摘要：Cloud computing has enabled clients to outsource their data to cloud and reap advantages such as low-cost, location independence, and scalability. After outsourcing data the clients may not be able to hold up to date data in the local storage. It does mean that the clients have to trust the cloud service provider for the security of their data. In order to know that the data is not tampered with by third parties, auditing services can help. These services can ensure the availability of data. One of the cryptographic techniques is known as Provable Data Possession (PDP) which is used to verify the integrity of outsourced data in cloud server. Zhu et al. presented a protocol which is interactive in nature for achieving zero knowledge proof system. The effective mechanism proposed by them for efficient probabilistic query processing and periodic verification could reduce the cost of verification. In this paper we implement the PDP protocol by building a prototype application that will ensure efficient audit services.
