—With the proliferation of hybrid clouds in both cost-saving and effectiveness, a growing number of users are building their own private cloud. However, private cloud can only provide limited resource, and always resorts to public cloud in order to meet elastic service requirements. Generally, public cloud is operated by commercial service providers (CSPs)(More)
In the dynamic, complex and unbounded Grid systems, failures of Grid resources caused by malicious attacks and hardware failures are inevitable and can have an adverse effect on the execution of applications. Therefore it becomes an important and difficult issue to guarantee that the applications execute normally in Grid environment. To alleviate this(More)
—Random Number Generators play a critical role in a number of important applications. In practice, statistical testing is employed to gather evidence that a generator indeed produces numbers that appear to be random. In this paper, we reports on the studies that were conducted on the compressed data using 8 compression algorithms or compressors. The test(More)
—Anonymous communication is a challenging task in resource constrained wireless sensor networks (WSN). However, anonymity is important for many sensor networks, in which we want to conceal the location and identify of important nodes (such as source nodes and base stations) from attackers. Existing WSN anonymous protocols either cannot achieve complete(More)

Nodes in wireless ad hoc networks depend on others for forwarding packets hop by hop. However, nodes may behave selfishly and do not forward packets for saving their limited resources. Approaches based on Vickrey, Clarke and Groves (VCG) pay to the intermediate nodes a premium over their actual costs to stimulate cooperation for their forwarding services(More)
In the Internet of Things a code resolution service provides a discovery mechanism for a requester to obtain the information resources associated with a particular product code immediately. In large scale application scenarios a code resolution service faces some serious issues involving heterogeneity, big data and data ownership. A code resolution service(More)
