摘要：To support cloud storage effectively, a Distributed File System (DFS) should be well-rounded with excellent features in multiple major aspects and without significant drawbacks. The main design goals of a DFS in Clouds include security, reliability and scalability. Traditionally, cryptography, data duplication and powerful machines are common approaches to support DFS. However, the success of such a DFS will depend on cumbersome key management, large storage and costly infrastructure, respectively. This paper intends to revise Blakley’s secret sharing and apply it to a DFS for both security and reliability without sacrificing the scalability in performance too much. With such a DFS, data will be split into multiple shares without any exposure of data content. Such shares are spread them in a storage cluster for high throughput effect. Once sufficient shares are collected, the original data will be retrieved. Transformation between data and shares is another form of encryption/decryption transition without any required keys. Such DFS is implemented and deployed with GPU (Graphics Processing Unit) to accelerate data store and retrieval processes. Experimental results have demonstrated the effectiveness of the new DFS.
