A Lightweight Security Protocol For Nfc-Based Mobile Payments, Mohamad Badra, Rouba Borghol Badra Jan 2016

A Lightweight Security Protocol For Nfc-Based Mobile Payments, Mohamad Badra, Rouba Borghol Badra

All Works

© 2016 Published by Elsevier B.V. In this work, we describe a security solution that can be used to securely establish mobile payment transactions over the Near-Field Communication (NFC) radio interface. The proposed solution is very lightweight one; it uses symmetric cryptographic primitives on devices having memory and CPU resources limitations. We show that our approach maintains the security of NFC communications and we further demonstrate that our solution is simple, scalable, cost-effective, and incurs minimal computational processing overheads.

The uneven provisioning of ecosystem services has important policy implications; yet the spatial heterogeneity of tree canopy remains understudied. Private residential lands are important to the future of Philadelphia's urban forest because a majority of the existing and possible tree canopy is located on residential land uses. This article examines the spatial distribution of tree canopy in Philadelphia, PA and its social correlates. How are existing tree canopy and opportunities for additional tree canopy distributed across the city of Philadelphia and with respect to three explanations: (i) population density, (ii) the social stratification luxury effect, and 3) lifestyle characteristics of …

The Case For Prioritism: Part 1, Christopher R. Little

Great Commission Research Journal

The global evangelical missions movement has embraced holism or integral mission as a framework for engaging the nations. Many astute observers maintain that this development indicates that present-day evangelicals are following in the footsteps of ecumenicals and repeating the mistakes of the past. The matter of the relationship between proclamation and social action in the mission of the church must therefore be revisited for the sake of the world. The first installment of this article seeks to highlight why the debate is still necessary, clarify the fundamental differences between prioritism and holism, recount the road to evangelical holism, and address …

Although many small churches are declining, research presented in this article suggests that on almost every measure of vitality or effectiveness (including newcomers), smaller churches are doing as well, if not better, than larger churches. Of particular note is that people in smaller congregations tend to find it easier to make friends in the congregation and are more likely to seek to make new arrivals welcome. Indeed, small churches may have a number of strategic advantages that are discussed and identified as ways smaller churches can make a significant contribution to the fulfillment of the Great Commission.
