With the rapid growth of large graphs, we cannot assume that graphs can still be fully loaded into memory, thus the disk-based graph operation is inevitable. In this paper, we take the shortest path discovery as an example to investigate the technique issues when leveraging existing infrastructure of relational database (RDB) in the graph data management.(More)
With the advent of cloud computing, it becomes desirable to utilize cloud computing to efficiently process complex operations on large graphs without compromising their sensitive information. This paper studies shortest distance computing in the cloud, which aims at the following goals: i) preventing outsourced graphs from neighborhood attack, ii)(More)
With the advent of cloud computing, it becomes desirable to outsource graphs into cloud servers to efficiently perform complex operations without compromising their sensitive information. In this paper, we take the shortest distance computation as a case to investigate the technique issues in outsourcing graph operations. We first propose a parameter-free,(More)
