Techniques for Efficiently Ensuring Data Storage Security in Cloud Computing

The Cloud Computing is the next generation architecture of IT Enterprise. It moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy. Here, focus is on cloud data storage security, an important aspect of quality of service. To ensure the correctness of users' data in the cloud, the authors propose an effective and flexible distributed scheme with two salient features. By utilizing the homomorphic token with distributed verification of erasure-coded data, the scheme achieves the integration of storage correctness and data error localization. The new scheme further supports secure and efficient dynamic operations on data blocks, including: data update, delete and append.
