This paper concerns the fundamental problem of processing conjunctive queries that contain both keyword conditions and range conditions on public clouds in a privacy preserving manner. No prior Searchable Symmetric Encryption (SSE) based privacy-preserving conjunctive query processing scheme satisfies the three requirements of adaptive security, efficient query processing, and scalable index size...
The fast increasing location-dependent applications in mobile devices are manufacturing a plethora of geospatial data. Outsourcing geospatial data storage to a powerful cloud is an economical approach. However, safeguarding data users' location privacy against the untrusted cloud while providing efficient location-aware query processing over encrypted data are in conflict with each other. As a step...
In cloud computing, load balancing is a very important performance factor. Frequent addition and removal of Virtual Machines (VMs) can cause load imbalance across Host Machines (HMs). Therefore, redistribution of VMs to different HMs needs to be performed periodically. This is called VM load rebalancing (VMrB). Existing VMrB solutions consider either balancing across HMs (inter-HM) or balancing within...
Cloud computing denotes the latest trend in application development for parallel computing on massive data volumes. It relies on clouds of servers to handle tasks that used to be managed by an individual server. With cloud computing, software vendors can provide business intelligence and data analytic services for internet scale data sets. Many open source projects, such as Hadoop, offer various software...
Cloud computing is a promising technology having ability to influence the way of the provision of computing and storage resources through virtual machine (VM). VM Consolidation is an efficient way to improve power efficiency and quality guarantee for on-demand services. However, it is an integer programming problem and as well as a NP-hard problem to find optimal solutions within polynomial time....
Private health information once confined to local medical institutions is migrating onto the Internet as an Electronic Health Record (EHR) that is accessed by cloud computing. No matter where it is hosted, health data is subject to security breaches, privacy abuses, and access control violations. However, novel technologies have new vulnerabilities, and allow new mitigations. In this paper, we propose...
