A nascent application enabled by such fog/edge computing model is that of community-based collaboration, where members pool personal resources together to accomplish a task, and data moves across edge resources. In such an environment, nodes that produce, store, and process data are often ephemeral, owned by different individuals, and distributed across multiple local networks. This poses new challenges at the network layer: how to automatically configure a network connecting distributed personal devices of social peers end-to-end, while enforcing privacy in communication among edge devices? We present PerSoNet, a novel virtual private network (VPN) that 1) automatically creates and manages private, authenticated overlay links across personal devices of social network peers, and 2) automatically manages software-defined networking (SDN) rules in software switches for packet forwarding, name resolution and mapping (for IP addresses and DNS names), and device network access control. PerSoNet abstracts away complexities, self-organizing a VPN that exposes IP/Ethernet network semantics, thereby enabling existing applications and middleware to be used in community-based fog/edge systems. In this work we describe the PerSoNet design and a prototype implementation based on SDN/OpenFlow and an open-source overlay. A prototype smart-task overlay application has also been built on top of PerSoNet to demonstrate its applicability and to evaluate key performance metrics of the system.","PeriodicalId":365939,"journal":{"name":"2018 IEEE International Conference on Cloud Computing Technology and Science (CloudCom)","volume":"35 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132834788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Memory forensics tools can offer a deployment-ready solution as compared to automated semantics derivation techniques, in the form of an integrated VMI-memory forensics architecture. A pending issue concerns the appropriate points in time at which to execute memory analysis routines. Analysis is required to execute in a manner not to overwhelm virtual machines but neither to lose out on short-lived in-memory data structures. This paper presents an on-going study to address what we call the 'event semantic gap', or rather the lost semantics of software-level events associated with the monitored behaviour. As opposed to deriving these events directly from the hardware level, we argue that translating them at the software level to recognizable events at the hardware level is more pragmatic, thus providing a fully integrated VMI-memory forensics architecture. Dynamic binary instrumentation (DBI) is a key enabler and promising results are demonstrated for the Xen hypervisor.","PeriodicalId":365939,"journal":{"name":"2018 IEEE International Conference on Cloud Computing Technology and Science (CloudCom)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128157803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the hypervisor's reliability, hypervisor device drivers must handle hardware failures appropriately. Our goal is to allow cloud vendors to test closed-source hypervisor device drivers against failures of their real hardware. Previous studies either require source code, can only test against virtual hardware, or cannot be applied to hypervisors. In this paper, we propose FaultVisor2, a hypervisor device driver testing framework that combines fault injection and nested virtualization. To test closed-source hypervisor device drivers, we inject pseudo faults to the I/O data returned from hardware to hypervisor device drivers. To test against real hardware, we allow the target hypervisors pass-through access to the physical hardware and manipulate I/O data of the target devices by intercepting I/O access. To apply to hypervisors, we exploit nested virtualization and run a small hypervisor underneath the target hypervisor to inject pseudo faults. We omit some nested virtualization functions, including nested paging virtualization, to achieve a close to real execution environment and reduce runtime overhead. In our experiment using the VMWare ESXi hypervisor, we found three types of errors which led to critical system failures.","PeriodicalId":365939,"journal":{"name":"2018 IEEE International Conference on Cloud Computing Technology and Science (CloudCom)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122428453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efficacy of healthcare remedies such as functional foods and dietary supplements usually spreads by subjective word of mouth. Though regular clinical trials could be employed, it requires significant cost in time and budget. We expect crowdsourcing can be an effective and efficient alternative to the costly clinical trials to achieve objective evaluation on healthcare remedies. The blockchain technology can alleviate the problem of information quality in most of crowdsourcing systems. Properly designed reward distribution schemes can motivate voluntary participants to provide with credible information. The distributed replication of blockchains can increase the information credibility by prohibiting malicious forgery. We also utilize the Amazon cloud system to enhance availability and scalability. To our knowledge, CORUS is the first system to utilize crowdsourcing, blockchains, and cloud computing for healthcare remedy evaluation.
