博士 / 國立交通大學 / 資訊科學與工程研究所 / 98 / A cloud storage system consisting of a collection of storage servers provides storage services over the Internet for long-term storage. A user can store data into the system and access data from anywhere at any time via the Internet access. However, storing data in a third party's cloud system brings a serious concern on the data confidentiality. We consider a cloud storage system model that has no central authority. A tight integration of public key encryption schemes and random erasure codes is developed. By using this integration, we present a secure cloud storage system, which guarantees the data confidentiality and robustness and supports the secure data forwarding functionality. Hence, in our storage system, a user can not only securely store data but also forward data to other user in a confidential way.
