The vulnerability of a network may suffer tremendous economic losses. From the perspective of network nodes, network security depends not only on the behavior of a node but also on that of its neighbours. We propose a non-cooperative networking vaccination game with economic incentive mechanism under a susceptible-infected-susceptible (SIS) epidemic process. In the game each node individually decides...
The rapid development of cloud computing expands the scale of modern cloud data centers, resulting in growing challenges of energy consumption. Load balancing of virtual machines(VMs), for the purposes of improving the utilization of physical resources and reducing energy consumption, has become a research focus in recent years. However, the existing researches mostly focus on how to maximize resource...
We present ODLV: an on-demand lightweight virtualization mechanism to solve the "lying endpoint problem" in TCG-TNC. ODLV utilizes dynamic root of trust and virtualization technologies of new commodity processors from Intel and AMD to dynamically establish a chain of trust and to insert a Lightweight Virtual Machine Manager (LVMM) under commodity Operating System (OS). The LVMM protects...
Assisted by the so-called service-oriented architecture (SOA) technique, it is more convenient and efficient to integrate multiple web applications. SOA holds lots of advantages, but there are still some security problems challenging us repeatedly. As well known by almost every developer, the security is very important for almost all systems. When considering security problems from the global view,...
Support vector machine is a novel machine learning method in recent years, the SVM with RBF is widely used in pattern recognition because of its good learning properties. If Support vector machine is applied into risk assessment, it will get better assessment results. But the performance of RBF-SVM is influenced greatly by the parameter of C and sigma. The principle of SVM and the essence of kernel...
