Abstract
The confidentiality and integrity are the most important issues in cloud storage system. We address
the privacy issue of decentralized cloud storage system using threshold cryptography. Once the user
uploads his data and deletes the local copy, he might lost the full control of the data. The major
challenges of designing this cloud storage system are to provide a better privacy guarantee and ensure
the integrity of data at untrusted servers in distributed cloud storage system. To achieve this goal, we
propose a threshold encryption scheme and integrate it with a secure decentralized erasure code to
form a secure cloud storage system, where the user generates a secret parameter participated in
system encryption and decryption of plaintext blocks in the combine process. So our systems can
prevent cloud storage servers from modifying data by providing remote data check and meets the
requirements of data robustness, confidentiality and integrity.
