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. A DFS is deployed with GPU (Graphics Processing Unit) as an acceleration option to tackle with scalability issue further. Experimental results have demonstrated the effectiveness of the new DFS.
