Relay attacks are passive man-in-the-middle attacks that aim to extend the physical distance of devices involved in a transaction beyond their operating environment. In the field of smart cards, distance bounding protocols have been proposed in order to counter relay attacks. For smartphones, meanwhile, the natural ambient environment surrounding the devices has been proposed as a potential Pro...

Though the mountain lion (Puma concolor) has been considered extirpated in Michigan since the early 1900s, sightings of the big cats have persisted in both the Upper and Lower Peninsulas. Reports of mountain lions increased during the 1990s, and the Michigan Department of Natural Resources (DNR) does acknowledge the existence of this species within the state. However, State officials continue t...

Machine Learning as a Service (MLaaS) allows clients with limited resources to outsource their expensive ML tasks powerful servers. Despite the huge benefits, current MLaaS solutions still lack strong assurances on: 1) service correctness (i.e., whether works expected); 2) trustworthy accounting bill for resource consumption is correctly accounted); 3) fair payment client gets entire result bef...

Consumer trust of Internet vendors is a major factor influencing the success of e-commerce. To enhance consumer trust, many e-retailers are experimenting with various trust-building strategies, including participation in third-party assurance programs. This study presents a model describing the relationship between trust and online purchasing, as well as related relationships with antecedents t...

Among recent trends in Quality of Service (QoS) provisioning in the Internet is the Differentiated Services Architecture, termed DiffServ. The successful deployment of Diffserv to provide a premium QoS guarantees to network traffic requires an effective admission control mechanism, which needs to be scalable and relatively simple to implement. In this paper we present a QoS network framework wi...

Utility grid environments o er programmatic access to information technology (IT) resources for applications. There is a substantial literature regarding admission control, resource reservation, and scheduling in support of engineering and scienti c jobs for grids. Typically each job is associated with a duration and peak requirements for resources. In this paper we focus on techniques to suppo...

Contemporary cloud computing solutions that have proven beneficial in supporting the needs of enterprise applications do not readily carry over to supporting cyber physical system workflows. For example, existing cloud platforms do not yet provide the stringent assurances on multiple simultaneous quality of service (QoS) properties expected by CPS applications including timeliness, reliability ...
