Cloud computing has been envisioned as the next-generation architecture of IT enterprise. The application software and databases are moved to the centralized large data centers, where managing the data and services may not be completely reliable. This paper studies the problem of ensuring the integrity and security of data storage in Cloud computing. The authors consider a scheme called threshold proxy re-encryption and secure erasure code, to verify the integrity and enhance server-side security of the dynamic data stored in the cloud. In the previous works, ensuring remote data reliability often lacks the support of either public audit ability or dynamic data transactions, this paper achieves both.
