In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, Cloud Computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy [3]. This unique attribute however, poses many new security challenges which have not been well understood. In this we focus on cloud data storage security, which has always been an important aspect of quality of service. To provide the correctness of users’ data in the cloud, we propose an effective and flexible distributed scheme with two salient features, opposing to its predecessors. By utilizing the homomorphic token with distributed verification of erasure‐coded data, our scheme achieves the integration of storage correctness insurance and data error localization, i.e., the identification of misbehaving server(s). Unlike most prior works, the new scheme further supports secure and efficient dynamic operations on data blocks, including: data update, delete and append. Extensive security and performance analysis shows that the proposed scheme is highly efficient and resilient against Byzantine failure, malicious data modification attack, and even server colluding attacks. Index Terms: Cloud Computing, Cloud Service Provider, Cloud data storage, Error localization 1. Introduction integrity of their data [2]. From the perspective of data Organizations today are increasingly looking towards security, which has always been an important aspect Cloud Computing as a new revolutionary technology of quality of service,. Considering various kinds of data promising to cut the cost of development and for each user stored in the cloud and the demand of maintenance and still achieve highly reliable and long term continuous assurance of their data safety, elastic services. The Cloud technology is a growing the problem of verifying correctness of data storage in trend and is still undergoing lots of experiments. Cloud the cloud becomes even more challenging. The data promises huge cost benefits, agility and scalability to stored in the cloud may be frequently updated by the the business. All business data and software are users, including insertion, deletion, modification, stored on servers at a remote location referred to as appending, reordering, etc. To ensure storage Data centers [1].

Users can now subscribe high quality paramount importance [3]. services from data and software that reside solely on remote data centers. The pioneers of Cloud 2. Problem Statement Computing Vendors are Amazon Simple Storage The proposed system has three important entities.

As a result, users are at the mercy of the live Cloud computing systems. their cloud service providers for the availability and International Journal of Science, Engineering and Technology 3 | Page Volume 1 | Issue 1 | October‐ November 2013 Third Party Auditor (TPA): TPA has expertise and capabilities that users may not have, is trusted to assess, audit and expose risk of cloud storage services on behalf of the users upon request from the users. A special entity is considered to ensure the security and dependability of the Cloud Server referred to as Adversary Model. The adversary is interested in Figure 1.1: Cloud data storage architecture continuously corrupting the user’s data files stored on individual servers. Once a server is comprised, an A.

As a complementary approach, System researchers have also proposed distributed protocols From the perspective of data security, which has for ensuring storage correctness across multiple always been an important aspect of quality of service, servers or peers. Again, none of these distributed Cloud Computing inevitably poses new challenging schemes is aware of dynamic data operations.

Therefore, verification of correct In this paper, we propose an effective and flexible data storage in the cloud must be conducted without distributed scheme with explicit dynamic data support explicit knowledge of the whole data.
