This paper argues for the utility of back-end driven onloading to the edge as a way to address bandwidth use and latency challenges for future device-cloud interactions. Supporting such edge functions (EFs) requires solutions that can provide (i) fast and scalable EF provisioning and (ii) strong guarantees for the integrity of the EF execution and confidentiality of the state stored at the edge. In...
Modern virtualization technologies provides an optimal use of underused hardware resources by sharing them among virtual machines hosted on the same physical machine. These technologies hence have been broadly adopted in many areas, such as server consolidation, virtualized network test beds, etc. A large-scale network test bed is considered one of the useful tools for evaluating or verifying advanced...
F5 is an information hiding algorithm based on frequency domain. It has been widely used because of its high-capacity and robustness. In recent years, many scholars have engaged in the field. In this paper, It is proposed for a extential steganalysis of information hiding for F5(ESF). By cropping IPEG image more times along the oblique direction, ESF can deal effectively with abnormal data and get...
